25.01.2022 We now have Momoi PINK 300lb mono in stock.

24.01.2022 I have been doing a few quick videos like this for private well moderated groups on things like, floats, slip tips, breakaway rigs, etc & they have been well received. I thought why not discuss the difference between ballasting for recoil & ballasting to prevent rotation on this page also. Mass is great for reducing recoil, but there are some places on a stock to put it which is better than others. There is also a compromise to be made, as we move mass forward to reduce muzzle flip we also make the gun more difficult to track. The choice is manoeuvrability or accuracy.

24.01.2022 Halloween candy!

24.01.2022 "Goodness gracious, bait balls on fire!" I had a wonderful experience this week jumping into balls of bait which had been pushed to the surface by striped marlin & sharks. The action on the surface was also spectacular as seals were harassing the bait from above & also trying to beat the marlin to the fish they had stunned with their bills as they crashed through the balls. I took the first fish I saw, which at 38kg isnt a huge one, but I was very happy. Throughout the day f...ish three times larger were encountered, & literally jumping onto the top of these fish as they worked the bait balls was like scenes from "the blue planet". I used a four rubber "Capricorn" with a 11/32 spear (turned down for a 5/16 Mori slip tip) & did need every meter of its range as I held just on the fishes back line & slightly in front of my target point when shooting as the fish sped past from my left. It was very satisfying watching the spear connect just behind the peck fin & then feeling the pressure start to build up on the bungie & rig line, the guys in the boat tell me it jumped a few times, but I didnt get to see that. I did use a breakaway rig clipped straight to the bungie & along with the slip tip there was going to be little chance the fish would throw the spear from jumping. The fight was short & uneventful, it towed me briefly as I hung onto the floats, before starting to pull back & clip off the rig rope. As I came to the six meter bungie & cliped it off I could see the fish was already upside down. By clipping off rig rope like this, it means we have all that useful rope to use again if & when needed. In this case i used that line to dive down & tail rope the fish, if I had needed to second shoot the fish I would have used this to clip the second gun to. Once tail roped, it was pretty much over. I doubt it took more than five minutes from shooting to boating the fish. I was using the "Green NV" rubber & I will be honest about my experience with it, it is great, however it isnt quite as progressive as the Salvimar I have used but it is progressive with lots more power. I am using slightly longer rubbers than the Salvimar & still feel it may be more than I need for this 11/32 spear. Maybe dropping down to three from four rubbers will give me just what I am looking for in regards to recoil & energy/range. Appologies to all those who have been trying to get one of these "Capricorns" recently, we are out of stock but they are the very next batch of guns which will be made. There isnt going to be any changes to their design or ballast as we are more than happy with how they shoot (particularly at that 7-8m range). We may offer them with some new trigger choices to make them even more flexible, i.e. euro & Aust/US spears on the same gun. When one like this is ready we will post something about it.

23.01.2022 Its fun to bang on about spearguns, however its the spear which gets the job done. We have talked about sectional density & the importance of not overpowering spears before & today we will try to explain why heavy shafts are preferred by many who chase larger fish. This matrix combines spear weight, diameter & the speed of the spear (72kph in this example to keep things simple ) to try to qualify why heavier spears which make a bigger hole, punch harder & put more hurt on fish than lighter spears when the brain or spine hasnt been hit. This is not designed to be the absolute authority ( for example we havent squared the speed which we could if we were chasing extra fractions), but rather give an example & a way to express the punch factor.

21.01.2022 I am still constantly asked about enclosed tracks on spearguns and why we dont use them. The simple answer is they arent necessary to prevent spear whip & can cause more problems and difficulties than they are believed by some to solve. Enclosed tracks will help stabilise spears in guns which are hogged the wrong way, but you will still have a bad gun. If the gun is made correctly the spear should always push or bend down into the track when fired. The gun should have the mass to resist the downwards force and prevent a large bend in the spear, thus making an enclosed track redundant. It really is just that simple & something we have been doing this way for more than a quarter century.

18.01.2022 These are the guns, still without a name, based upon the gun in the Cool Runnings post from December. They are exactly the same length stock as the Tasman but are deeper in the belly & weigh an extra 500 grams (2.4 kg total) & a bit more costly being proper teak. We did a small run using the best Burmese teak ( not plantation) we could source, there are five vertical laminations in the stock & one unidirectional laminate of carbon fibre between the belly & the stock. Ever...ybody on the team has grabbed one of these but we still have a couple left. I think they are really versatile & can shoot a 1.8m 7mm spear with one or two rubbers & a single loop of mono, up to a 11/32 spear with double loop of mono & breakaway set up as an entry level gun for Bluewater. The guns are finished in 2 pack & have an American trigger ( although some people do use euro spears in these guns, it works but we arent recommending it). I also know that a couple of our Tasman guns were finished in this run & although the web page reads out of stock there are two available now ( send a pm if you are interested in either model ). The big Capricorn gun is out of stock ,but is our most popular model & the timbers for the next run are being sourced, most likely all rosewood ATM, but we have a bit of purple hart, Qld beech & a few other timbers in stock if anyone wants to discuss something special for themselves.

16.01.2022 I need to go here! We have an amazing amount of resources now to help us find fish. This shot is from the Bureau of Meteorology. It explains the presence of the cold green water off Pt Stephens & also where the best water is. I expect, like the majority of years the current will touch the Sydney Coast around the Australia Day weekend bringing great diving & fish. I cant wait that long. Its work, honestly! We have new guns to test & I must go!

16.01.2022 Mid handled guns? What are a few of the advantages? The first photo is a 1300mm beside an 1100mm. Both these guns are the same to track through the water & have the same amount of rotation at the moment of inertia, however the mid handle gun pictured shoots a 200mm longer spear with all the extra accuracy & range a correctly set up longer spear provides. In the second photo are rear & mid handled 1300s & rear & mid handled 1100s for comparison. Not only does the mid handle offer an advantage for tracking & reducing the rotation when firing, it has great utility in dirty water & in caves. How many people have tried this type of gun?

16.01.2022 There is a great deal of choice in speargun rubbers, that is a good thing. Correct information will hopefully allow you to make the best choice for your own needs. I understand that 14mm rubber is easier to stretch than thicker options & in many cases this gives an advantage. If the thicker rubbers of the same composition are stretched to the same percentage as the 14mm then they will be equally as efficient, it is just it requires more strength to do so. I also believe tha...t 14mm rubber is gaining a good reputation because it is lower in power than the thicker options. Many spearguns are overloaded & under ballasted so dropping from two 16mm rubbers to two 14mm rubbers improves their accuracy by reducing the energy & recoil by 25%. Also if the 14mm rubbers are progressive instead of reactive & are stretched a wee bit more than you would do with a heavier rubber then that extra stretch increases efficiency, & the spears velocity may be similar to that from the thicker longer rubber. Thinner rubber is believed by some to be better because most people can stretch it further, if your speargun is ballasted well & you can load the thicker rubbers to 350% stretch they may still be the best choice for you. This video is a very quick look at the cross section of rubber to qualify the above comments. It shows some of our heavily ballasted test guns which allow us to compare different rubbers without recoil being too much of a factor. Hooks law cant be applied to rubber like other springs & we have found the best way to judge rubbers is empirically. Simply, we use a point blank method and see where the spears land on target using a variety of different rubbers. I dont put much authority on just putting the rubbers on a set of scales & stretching them, it doesnt measure the snap or efficiency. See more

15.01.2022 The question which seems to be asked daily by people is what is the best speargun? Like everyone else I have an opinion & bias, but hopefully this will help people to make their own informed decisions. I always suggest that people start with thinking about the locations they fish with the speargun & the species that they are likely to encounter, & then decide upon the best spear length & diameter for the task before deciding upon the gun. The best choice should be the...Continue reading

15.01.2022 It may seem a bit quiet but we have been busy. We thought it was about time to make a fully composite speargun. First it involved making a plug/ pattern so as to produce a mold, & then of course the mold & tooling for infills. Then finally some guns. Its been about five months from deciding to go that way to having those two prototypes ready to really test. The heavy blue gun has been shot by several people experienced with large Bluewater type guns & the feedback has been v...ery encouraging. The guns are hand laid using several composite materials including Kevlar & carbon fibre. We werent using the carbon to reduce weight, but for rigidity & the Kevlar is to make the stock much more impervious to heavy bumps, we expect several generations to appreciate these guns if we can still go spearfishing. The bare stocks are close to four kilo & will be made heavier or lighter depending on the chosen spear set up. These are the colours I personally like, but we are looking at different spray choices & options going forward using the best marine 2 pac paints. I doubt many would want a 5.2 kilo ( total weight) two rubber gun with a 7.5 mm spear, but that cool runnings gun is a bit of a test for us to really try to quantify recoil & test a few other theories. It is weightless in the water being totally neutral & balanced with that spear. For interest the weight of the blue gun is just over 7 kg in that set up. I still wouldnt recommend shooting it one handed as it is. Thank you everyone for maintaining & showing an interest in these guns, I expect we will have more feedback on their performance soon.

13.01.2022 We moved the infills around a bit in the big mould to produce this carbon finished gun. Its the same length & bandstretch as the Pacific model but 1.8kg heavier in the stock & the mid handle is closer to the trigger mech. Having the handle further back we feel may make it easier for those used to euro guns to transition up to bigger bluewater guns. The carbon look is also interesting & feed back on this finish has been positive from a few. The photo shows the size difference between the big composite guns & an 1100 tube gun for comparison. Pink is featured here, however, band lifters & loading pads can be made to choice & handles can be sourced in a variety of styles & colours also.

13.01.2022 Most of the content we post here is generated from questions we receive. This post is another one to clarify a question about spear penetration. When the speed of two different spears is equal, then the longer spear will penetrate further ( & also travel further in range). It makes no difference if the spear is 10mm or 6.5 mm, if they are the same length, material & starting at the same speed, then they will have the same sectional density. The myth that a thinner spear pene...trates more is just that, a myth. See the matrix on sectional density in this post, I havent bothered to fill out the other spear diameters because they are all the same as the 3/8 spear. We have posted the relative index on punch factor again because this is another important piece of spear & spear point selection. The matrix above is just for straight shafts, (not prangers & points greater in diameter than the spear, these will have different factors , & also change the sectional density). The old adage about putting the cart in front of the horse is very relevant to spears & spearguns. Just remember that its the spear which hits the fish, the gun is important, but should be second to the spear & type of point selected when designing a piece of kit for a particular fish & situation. Once the spear & point is determined, only then should the design of the gun best suited to deliver the best accuracy, reliability & utility be considered. We will be posting more on these topics going forward. See more

12.01.2022 Very pleased that the improvements in accuracy from adding extra mass to a speargun correctly is being so well received.

12.01.2022 We had a plug & moulds made for ballasts on some 1300mm & 1400mm multiple rubber timber & carbon guns. We also couldnt help ourselves, & just had to fit a set to a little 1100mm mid handle gun. These ballasts add another 650 grams to almost any timber gun without changing the buoyancy. In clear water, range & accuracy is much more important than a minor loss in tracking speed, & these ballasts will certainly improve accuracy on guns with multiple rubbers & are easily retro fitted, for people looking for these improvements.

12.01.2022 Almost daily we have been having people asking about their rig lines & floats for bluewater. This is how we go about setting up a breakaway, others will most likely have different ideas, but we can confidently say this has worked for us. Firstly, the floats are important. As we are 99.9% diving out of a boat & usually making multiple exits & entry to & from the boat, managing the rig cord & preventing tangles is important & with two or three divers its much more critical. Th...e shape of the floats above are the best. These floats can be left in the water between drifts & towed behind the boat saving a lot of hassles. The other shapes & types are not as good in this area & often blow out & cause tangles. The main reason I have a few sets is for when a friend turns up with another shape we can prevent any anxiety by using my spares. I also only have the second float about 500mm behind the first if using two, there is no point in having several meters between them. The main line in the photo is just 8mm ski rope, spliced with a Brummell. Its about 23m long, (I never have a flasher deeper than 16m but thats another post). There is a large hard shark clip ( they come in heavy & light gauge) on the front followed by the small yellow float. The float keeps the shark clip out of the way of the gun & breakaway setup. The end has a loop which a shark clip on the first float takes. This is all I use over coral for tuna, no bungee on coral ( usually). If I am looking for top water fish like wahoo & marlin I like to add 6m of bungee at the front of the rig ( straight to the breakaway). Again I have a float here to keep the shark clip out of the way. Six meter of bungee is fine for me, I have lost a couple of bungees over the years when people have borrowed them & clipped off to them in the middle, dont do this. When fighting a fish I can still pull it up & clip off on the ski rope as I gain ground & that last 6m isnt so important. Plus its nice to have that bungee working even at the very end of the fight. About breakaways, I really only use one to stop the fish using my heavy gun as leverage to its advantage during the fight, its not so I dont loose my gun. So much is happening during those first few seconds after landing the shot that the gun is just another problem to deal with. If you are not targeting really large fish or using a several kilo gun, not using a breakaway set up can be a good thing to consider. Again, this post covers only one set up which works, there are other ways to achieve the same results. Just remember to always try to keep it safe & simple. See more

05.01.2022 There has been a bit of discussion going on in regards to which spears & points travel & penetrate further. Below is a matrix using sectional density to explain the physics. The top matrix is just a bare stainless steel spear ( no points or flopper). Below are examples of what happens to the sectional density of our spear when we fit a Riffe slip tip (11mm) & a 5/16 Mori slip tip (9.5mm). The conclusion to take from this is if you are going to use a 3/8 slip tip, use a 3/8 spear, if you are prepared to turn down a 11/32 shaft to 5/16 for the first couple of Inches a 5/16 slip tip like the Mori gives excellent results.

04.01.2022 What do you think of this lineup?

04.01.2022 We receive quite a few messages & questions sometimes both, especially about our large molded carbon composite speargun. They go something like this I thought carbon was too light for a big gun, it must recoil a lot?! These type of messages & also lots of comments on social media about many different guns has made me realise that a lot of spearos haven’t heard of Archimedes or his principle the force of uplift on a submerged object is equal to the weight of the water dis...placed by it. When you read or hear a comment about a speargun being too heavy or too light, look at its mass, volume & displacement before accepting those opinions. The second photo is a 4.3kg composite stock floating in water. It floats, is that stock too heavy because it is 4.3kg when on dry land? That stock is displacing about 5kg of water & is weightless until all it’s hardware & the spear is added. Will it be too heavy to use? No, it feels no heavier than a small gun & that 4.3kg mass helps to prevent recoil & muzzle flip. The forth photo shows a few prototypes with wing kits fitted for testing all sorts of theories from muzzle flip, recoil, rigging, & especially the rotation & moment of inertia when fired. Those wings have mass, they have weight on land however in the water they are essentially weightless. They however still have mass & this mass prevents recoil & muzzle flip. The fifth photo is another ballast, one which is easily retrofitted to any tube gun. This again adds mass & will increase a spearguns weight on land, it’s weight will be neutral in the water, however the extra mass will soak up recoil & muzzle flip. Please think of this the next time you hear an opinion about something being too heavy, think about how much volume it has & how much water it will displace before forming your own opinion. If it helps think of old Archimedes himself sitting in his bath tub formulating the principle & shouting Eureka! See more

03.01.2022 Why do we sometimes miss? Let’s assume that it’s not the spearguns fault this time & we look at ourselves. As we are lining up on a fish there is a lot of visual information that our brains have to process. We are in a different medium to air we are moving three dimensionally & so is our target. Our brains will sometimes take shortcuts & try to guess the future & base its interpretations on the information it guesses is more important. So what does this all mean? I’m sure... a lot of us have heard the story about a driver having a micro sleep to be awoke when the car leaves the road & then steer into the only tree or pole rather than away from it. This is the brain focusing on what it considers a more important object instead of the empty space. Fatigue, stress, urgency, etc are all contributing factors when subconscious decisions override our conscious ones or cause us to also have visual illusions. A typical visual illusion with spearguns is the brain telling us to shoot when the rubbers are lined up on the target & not the spear. Yes it happens & you will shoot high. Having the rubbers closer to parallel with the spear does a great deal to eliminate this. I believe preventing visual illusions like this is far more important than any gain in reducing muzzle flip. Simply change your muzzles or fit some band lifters to fix this, with added benefits. Your sighting picture now, it’s great to say you shoot instinctively but your brain is still processing huge amounts of visual information. If you don’t have good reference points such as the spear tip the brain is much more likely to guess & the guess is often going to be based upon the strongest visual information ( or distraction) rather than a consistent or accurate one like the spear tip. This is why spear length & overhang is so important for our brains accuracy ( not so much the guns) the spear length & tip should be a consistent & also visually important reference or our brain will focus on something else. If you are making changes remember it takes a minimum of two hundred shots with those changes for muscle memory & instinctive memory to learn. #octosub #thecompletespearo
