Reinventing the underwater gun

[iknowmy3tables]

Early spear guns were powered w/co2
small diameter barrel to fit spear snug
one spear w/line and barb then 'drivers' shot after that to subdue large fish
Hans Hass was the guy who wrote book.I read it in many years ago.

there still are CO2 spear guns I've heard that their awesome

Oops...

FYI, pressure increases by One Atmosphere for every 33 feet of seawater (FSW). so, at the surface you have one atmosphere, in 33 FSW you have two atmospheres, in 66 FSW three atmospheres etc..

Wow! Does James Bond know of this?

The navy SEALs use a similar gun....

8) I love cool guns....

[SpudUke5]

I only can understand so many words.

I understood some of it becuase some of the words are the same as in Ukrainian.

I did get the names though

But anyway, its a very nice gun.

This one

That's some of the most vicious looking ammunition I've ever seen. I do know how they work and all, I'd just never actually seen a picture of them before. There's just something mildly amusing about seeing someone load large metal darts into a rifle clip

That's some of the most vicious looking ammunition I've ever seen.

Rifling the projectile is useless when firing through such a dense medium as water, hence the need for long drag stabilised projectiles.

[Jared Haehnel]

I once read an article about these guns and some thing about the fact the object is long and straight and moving at the high speed, helps to keep the projectile on course. But Jack' explanation sounds better...

Kind of sucks that it is factory reloaded...
