Welcome

Amazing gun, such perfect dimensions. Will you put bands on it before sending it off? id be curious how the bands lay on it when loaded. Anyways beautiful craftsmanship as always.

Lol so whats you guys' favorite spearfishing video?

So you don't think that a 6.5mm spear shaft will have a higher initial velocity than a 7.5mm spear shaft? A heavier object takes more force to get it going, but once it's going it retains more energy for a longer period of time.
But we are talking about two same size spears.

I would never trust a penetration test. The only reason being that I always find myself saying either "I cant believe the spear went clear through that fish" or "I cant believe the flopper didn't even get through". I realize a foam pad and a fish are different but the same rules apply.
A chronograph is the only way to get a definite result. As someone just said on here "two spears with the same mass, the faster one has more power " Simple as that.

I am in Orange Beach AL. If there is someone close by with a roller gun we can shoot it over a chronograph. And the chrono is conclusive. If you have two projectiles of the same mass and form (spears), the one that has the fastest muzzle velocity will have the most energy. This equals flatter trajectory and more penetration. Penetration comes from momentum, or the remaining energy when it reaches the target. If you want to prove it to yourself, go to any ballistics program, select a bullet, then run the program with two different muzzle velocities using the same projectile. The one with the higher muzzle velocity will shoot flatter and retain more energy downrange. Whether you are shooting bullets, arrows or spears the science that predicts performance is called ballistics and is a function of the mass and form of the projectile and the amount of energy that is used to launch the projectile.
No matter which method you use to test the theory, (chronograph, Go-Pro, or penetration test) you need to make sure the butt end of the guns are supported in a manner (such as against the pool wall, perhaps with a foam cushion between the gun and wall) so that differences in recoil due to differences in the mass of the guns will not affect the results.
If the roller guns provide a smoother power curve and deliver less recoil, they may seem more accurate to some users for that reason. I think this is one of those - "If it floats your boat, then use it!" scenarios. Personally, I like to keep it simple so I will continue using a conventional style. If you like the roller guns, then that is good.

Congrats for being the most level headed person in this discussion. We have a member MIGHTYKC in your area, but I'm not sure if he has any rollerguns. He may though, if I recall correctly he has a lot of different spearguns.

Awesome. And many more coming

They do appear to go off simultaneously. How'd u pull that off?

Raw is good. I ate 5 lbs of poke in the last three weeks with two trips to Hawaii. This may have been posted before but what's a good recipe for Shoyu (soy) poke? I'll use fricken tilapia. That stuff is so good.
And Marco, hows the diving in Panama? Have you been in the Pacific yet?
Hank while in Hawaii have u ever gotten poke from tamuras in Kailua near Kaneohe/ lanikai. Insane good. Lots of ahi poke the soy kind and the mayo kind (sunrise I think it's called). Also tako salad with some seaweeds in it I've never had anywhere else. Man probably the best food I think I'll ever have
-
The sauce looks boss
-
One that I cannot wrap my mind around is how in the southeast mainland we consider Chubs the ultimate trash fish. In Hawaii, though, chubs (nuenue) are considered a score and even eaten raw in poke
I've never tried it nor known anyone who has, but heard the meat looks and smells bad. When I see pictures of it on the hawaaiin pages and forums it looks dark and mushy but not as bad as floridians had described it to me
-
Wooo, that's the good stuff.
-
That said the video you posted is pretty cool George. Never seen dogtooths in that setting before

I can't choose a Broderick Whittaker video I like best to post lol. He made a bunch of videos shore diving and kayak diving and Jetski diving in south Afrika in dirty water with bad sharks, they are great but really old school
-
You're all horribly misguided. Brod whittackers videos are the best. And that one from New Zealand of the giant tuna behind the fishing boat. Those actually make you feel something .
-
Hard diving guys. I been watchin their vids since you told me about them
-
Maybe not, a Michael Jordan is a Michael Jordan [emoji6] also think about the fish guys shoot in the Bahamas with polespears... but give those same guys a good gun in the same spots and see what happens! Right?
No way you lost me there. I can't even watch Bahamas videos . How do you miss a 40lb fish in 15 feet of water?

They come up all the time in these discussions, Barry is an abnormal human and doesn't belong in a conversation with mortals. Man dives with a 1950's mask! The pipe gub and flopper is space age for that dude! But the guys who are that good, and CAN land fish because they are that good with gear that is less capable are not a argument.
Don't put them that high up on a pedestal georgey! There is something going on there though , poison spears maybe.
-
I feel like the greatest argument against the need for heavy duty gear are the paxmans. One could argue, though, that they dive where the fish have never even heard of people before.
