  • New Gear!

    Thanks for the nice review shred, glad the wetsuit size was right. Remember that threading the belt through conventional weights will make it shorter. If you haven't done so already put weights on it and try it on, you may not need to make more holes.

  • gun care

    Depends on the existing finish. I can't remember if the JBLs have a coating over the wood, probably they do, you should be able to tell. If so all the gun needs is a good rinse after use. No oil for the trigger mechanism or anything like that. If you're not going to use the gun often, take the bands off and put them in the fridge, they will not deteriorate like that.

  • mako and rabitech likeness

    I just got an email that I found interesting and entertaining, from a Taiwanese diver now living in Florida, who reads the forum and was interested in Pursuit gear. He gave me permission to post the part of it pertaining to Rabitech and Daniel Hu.

  • homemade polespear

    Mike, I can't give you any numbers, but the JBL hollow alum polespear wall diameter is a fraction of your alum pipe. It's less than the thickness of a dime. And it's plenty rigid to stay straight with a very strong band.

    Quote from Mr paul

    Tell Jill we'll buy them if they're not ridiculously overpriced like everything else they sell.

    c'mon man, it's cryptic <img src= " class="smiley" srcset="https://spearfishing.world/forum/images/smilies/emojione/1f606@2x.png 2x" height="23" width="23" loading="eager" data-tooltip="biggrin" aria-label="biggrin">

  • new dive mask

    A really well fitting mask can be worn with the strap completely loose. Normally the strap should not be very tight.

  • Speardiver C90 or C100 carbon fins?

    In Speardiver carbon fins the 90 and 100 designations refer to the total fin length (blade + foot pocket), from the front edge of the blade to the heel of the foot pocket. C90 fins are 90cm total length, C100 fins are 100cm total length. The length of the blade in C90 fins is 78cm, the length of the blade in C100 fins is 88cm. The length difference between C90 fins and C100 fins is 10cm.


    It is true that the longer fins provide a little more propulsion, but at the expense of maneuverability. To offset the reduced maneuverability Speardiver C100 fins use a round cut for the front edge. The round cut offers a little less surface area, and no corners so less chance of the fin catching on structure.


    I intended to market the Speardiver C100 fins for non-spearfishing freedivers, because theoretically they don't need to break form as much as we do when spearfishing. Think how we scramble on the bottom to look in a hole, or turn around fast to shoot a fish. Also in response to current market trends, because other manufacturers are offering the longer fins exclusively, and many divers are now convinced it's the only way to go without really understanding the longer fins.


    This is how I explain the performance difference between the C90 and C100 fins. When you kick the blade pushes against the water and flexes, storing energy. Carbon wants to straighten out very fast and release this stored energy, resulting in your forward propulsion. It takes the longer fin (C100) more time to straighten/release its energy. So what you get is a slightly delayed action, the fin continues moving you for a little longer after you finish your kick, so you get more for your kick. I know it sounds appealing, but as with everything when you exaggerate one aspect of the fins performance you lose in another area. You can't subject C100 fins to your whim as you would with the C90, you can't accelerate as fast from a complete stop. The longer fins dictate your pace. Having stronger legs/kicking harder and faster doesn't really change anything here. You have to adjust yourself to the fin and let it do its work. The majority of divers who use the longer blades don't have the experience to understand the advantages and disadvantages, they simply bought into them. Still there are a few very experienced spearos who prefer the longer blades.


    Obviously there's a limit to how long a fin can be while still being effective. If longer is always better then why not a 110cm fin, and then why not 120cm etc. You must conclude then that at a certain point the fin will become too long. Different people put that number in different places. The trend now in freediving fins is around 85cm for the blade, and I believe it's too long for me and %99 of freedive spearfishermen. Yet due to smart marketing the 85cm length blade is becoming the standard, and the 78cm blade is sometimes called "short". 90cm fins are not short! 10 years ago they were the original "long fins". I think 90cm total length (78cm bladed) is the ideal length for a spearfishing fin, and is what I and most guys use, you can't go wrong with it. But I acknowledge that divers who hunt in certain conditions and/or have a specific diving style, may benefit from using a 100cm fin.


    The same logic applies to the fins angle BTW, the ideal angle being 25º. DiveR took the angle to an extreme 35º, with the end result of easier surface swimming but poor power return on an ascent.

  • Some of my personal art

    I received the yola and marlin prints from Pucho today, they're absolutely beautiful. There's color and details that don't come through the online pictures. The framing is flawless. Thank you very much Pucho.
