Yes. My business name is now Speardiver International. trademark is Speardiver.

I'd try the edge of a folded piece of sandpaper. Depending of course how much you need to reduce the edges of the notch.

Great story John. Those head collisions are tooth shattering and particularly painful. Maybe because you're fairly relaxed and completely not expecting it, combined with the momentum of planning to go through the area where the obstacle decided to be. Until now I only felt this hitting the bottom of the boat. Barnacles must be delightful. And that happened through the hood?

What gun were you using for that cobia?

PS I need a pic of the brown suit for the store but the two bleedin' heads pic may be a little too rough for the internetz

Sniper! Finally I get to see the gopro sling rig. Those are some healthy fish

It's possible. Please contact me through the store, I don't catch all the posts in the forum, and don't want it to look like I'm ignoring you if I miss your post.

Pathos run normal as far as I'm concerned. I had a few guys say they're nice and wide. They're definitely not narrow.

:thereyougo:

Forgot to add that IMO foot pocket tendon add to the water channeling effect which stabilizes the blade. I can't offer anything to support this other than my hunch, having tried these tendon-less foot pocket fins.

I'll post a pic of what two wraps over the line release looks like.

The weights of the blades and foot pockts are listed in their respective threads, blade specs are also listed in the store Speardiver C90 Fin Blades - Speardiver. You can add them up to get a weight for the complete fin. However blade volume and feel, which is something you can only know by handling it, means more to me than a weight measurement.

Phil, I owned only one pair DiveR blades, but I've seen a few come through my shop. I consider DiveR to be strong blades and only used Charlie's story to support my idea that foot pockets without tendons are not a valid option. But if you want to discuss them at depth; I don't think much of DiveR fiberglass blades with their overdone 30 degree toe angle, no water channeling rails to stabilize the blade, and overall cumbersome feel. My fiberglass blades are simply better in all those aspects, when I finally do make them available.

I disagree with you about manufacturing, easier said than done. It takes a specific set up, materials, and manufacturing methods to produce good blades. Never mind with consistency. Vacuum bagging doesn't cut it.

I've seen and tried many many blades because that's what I do. IMO if there's one blade that will last in foot pockets without tendons it'll be one like the old flat Waterway blades. As you may know they're not laid up to create a flex pattern. The flex is created by machining layers off one side of the blade that's one thickness throughout to begin with. Done properly this allows for much more precise tuning of flex than layering. But even so this will be a relatively heavy fiberglass blade. IMO with layering you will never produce a usable carbon blade that will withstand lack of tendon support. It's just a dream, that's why no one sells them and no one ever will. The company would go broke from replacing broken blades.

In theory yes but practically no. There's a practical limit to how many layers you can use and how you can arrange them, and still have a light reactive fin. A uniform blade with an as you say parabolic flex pattern hasn't even entered my considerations. I don't know if you've used DiveR blades, they're as strong as it gets as far as backbone, so much so that I find them too heavy and uncomfortable, and they still broke. Barring a manufacturing defect which is always possible, this really demonstrates the problem with lack of blade support. If this happens with fiberglass it should be clear that carbon doesn't stand a chance. If the blade is going to be so thick in the back that it doesn't break, the fin will be too stiff to use. Otherwise there will always be a point of transition in thickness where the stress will be focused, and the blade will break there.

You don't mean the other way around?

What you just noticed it LOL it's been a week. I guess that's a good sign, I was worried some may find it distracting. If anyone doesn't like it let me know here because I'm undecided. Later I was going to add fish you can shoot at <img src= " height="23" srcset="https://spearfishing.world/forum/images/smilies/emojione/1f606@2x.png 2x">

300lb mono no problem. 400lb a little tight but works fine. Either way myself and others who are better divers than me agree that for this length gun two wraps is a waste of time.

depends on the shaft and notches. Some have smoother notches than others. If it's a stainless steel shaft you can make the notches nice and smooth. Avoiding sawing the dyneema over the notch when loading also goes a long way towards maintaining the Dyneema. Using replaceable wishbones also takes the worry out of it.

Quote from Chuckd

So do you believe the softer tenons allow better flex of the entire blade?

I believe tendons should be of moderate stiffness. Enough to give the blade some support (which very soft tendons don't, just like the tendonless foot pockets), but not so stiff that they don't allow the blade to flex at all.

Blades take an amazing amount of stress pushing us forward, we usually don't think about it and just expect them to work. And we want them to be light and reactive at the same time. It's too much to ask when using a foot pocket that doesn't offer good support.

For me the process is a little different:
1. I see a beer cap with the sharp edge pointing up lying on the boat deck.
2. A heat flash goes through my head and the word "assholes" resonates.
3. For a split second I consider picking it up, then decide against it.
4. Next thought is that if when I find out who tossed the cap and shove it up his ass, he'll be much less likely to do it again. On second thought yelling at him will suffice.
5. Although I know from experience that guys who do such things are careless ~`~`~`~`ers who I probably don't care to dive with, there are others in the middle who I don't want to put in an uncomfortable position, so I try to stay calm and explain the obvious.
6. Boat nazi about sums it up but I don't care. I've seen accidents and I'd rather be in one piece than be the nice guy.

Lunkerbuster is not "lankybuster" even by a stretch. He's a big guy all around. Maybe you're thinking of yourself in high school Judah.

Gerald, if you're in the area you're welcome to come and try.

You got it Don.

Used Canon SD1000 camera and waterproof housing $80. 4GB SD card included. The cost of camera and housing new was over $400. The camera and housing are in like new condition so I'm posting stock photos only. The video function of the camera is not working, the files it produces appear to be corrupted. Everything else works perfectly. $6 shipping or pick up in Fort Lauderdale.

This camera served me well, here are some pics I took.
