High power pneumatic speargun?

[Marulken]

Hi

Im new to Spearfishing but had been doing hunting for many years.

When it comes to pneumatic Spearguns the main pressure camber is 20-25 bar on air.
Does anybody know why there is no CO2 Gun?
A CO2 Gun have usually 60 bar, seems that one could easy gett more pressure.
Does anybody know anything about this?

I don’t know much about C02 guns but I know they are very susceptible to temperature change and as some gas is discharged on ever shot the powered source has to be replaced quite often.
There must be other good reasons as well, in the U.K. they would have to be lincenced as the Co2 weapons are considered as fire arms.
Also... a modern, dry barrel air gun is a very powerful gun with little recoil and good reliability.

I have looked att dry/vacum barrel pneumatic Guns and they operate on 20-25bar.
To Exchange a cartridge after one shot is not that big of a deal, only a cost.
The russians have underwater Gun for millitary, that work upp to 20m.
To make a gas propelled gun with same effect would be sweet.
Maybe there is no need for extra Power....

There have most definitely been production C02 guns produced in the past, for what ever reasons they have obviously not proven popular.
Hopefully someone who knows about these things will chime in...

Dude... what are you planning to shot @ 20m range? Whales?

Where are you planning to shoot whatever you plan to shoot? Viz needs to be more than great. Not to mention you have to be helluva shot to shoot a moving target at distance uv.

Ohh... and spearguns (all fun ones at least) are prohibited here in grey, dull ol Sweden.
Yay! [emoji1236][emoji1236][emoji1236]

Well I was more thinking max 5-10m but having extra power could not harm Look the faster the spear shoots the less ahead lead and elevation will be needed. So speed is not a bad thing.
Questions is maybe such a gun would be require a licence And therefore is doomd..

And about sweden Well you can have a Spearguns but you need to get licens from the police and you cant fish with a Speargun. So yes your right.

 

[foxfish]

@popgun pete will probably know something about C02 powered guns.

Well, good luck with that. Maybe if you’re a cop you could write yourself a license, but other than that, forget about it! I know there are a few guys that have a license from waaaaaay back, like decades ago, but other than those very few I have not heard of anyone getting a license in the later years. When I applied the cops more or less laughed out loud.

You can own a gun, and you don’t need a license. But the gun can have only 1 band and the distance from the muzzle to the notch can be no more than 50cm. And you can’t shoot fish with it. And the effective range is like max 2m so you’ve gotta be pretty stealthy!

But, you know, rules are meant to be broken. Especially stupid ones. I’ve seen a few YT vids of spearfishing in Sweden, so you go ahead and do as you wish! And post the results while you’re at it! [emoji16][emoji823]

Carbon Dioxide spearguns are expellable gas open cycle weapons whereas pneumatic spearguns are non-consumptive of gas because they are closed cycle weapons. When seeking a definition to separate spearguns from say air rifles the key attribute has been whether the projectile is shot out of the gun by a spring or is blown out with a large quantity of gas following behind it. Expellable gas spearguns are usually weapons controlled by the State where restrictions and permits apply, but fortunately for us there are no restrictions on pneumatic spearguns because they fall outside the scope of the regulations. As they are not limited by the operator’s strength in loading them carbon dioxide spearguns are banned virtually everywhere.

Yes you can own one single rubber Speargun under 50cm but you cant fish with it, that would be illegal to do.
Do my Spearfishing in norway where it is legal to Spearfish.

So thank you for your explanation, so the reasons are clear.
No high power Spearguns due to licensing.

 

[popgun pete]

There are high power spearguns that don't infringe on the rules because they are non-consumptive of gas, but operate way beyond the pressures usually associated with pneumatic spearguns and that is the hydropumped hydropneumatic spearguns. The grandfather of such guns is the Alcedo “Hydra” which is discussed here: -

Not too long ago, there was still a co2 gun in production. It's called the Maco2. Look it up.
CO2 guns are great for spearos who for one reason or the other can't load a gun the traditional way (e.g. being injured or disabled) but still want to spearfish.

The Maco2 is basically a revamped Pelletier CO2 speargun, however its use was limited to France’s overseas dominions (colonies) as it was illegal to use the Pelletier speargun in France. Hence like the Pelletier the Maco2 is very limited by rules formulated many years ago, but which have very little likelihood of ever being changed. Countries such as the USA have a much more liberal attitude to weapons and firearms, therefore someone in the USA could buy one and use it. The guy who runs the Maco2 enterprise would like things to change, however his ongoing campaign pretty much falls on deaf ears. You could use the Maco2 on land as it functions like any firearm, whereas most spearguns on land will destroy themselves after only a few shots, hence they tend to be self-limiting.

 

[Diving Gecko]

I can't recall who it was but a US spearo did indeed buy one as he had a shoulder injury and couldn't use a regular gun. He might have posted about it here but definitely posted about it over on spearboard. I have a feeling his shoulder heeled up and he might be back to bandguns now.

I actually saw one of these in, of all places, Sri Lanka.

Here are some of the Maco2 spearguns that I stored photos of a few years ago.

 

[popgun pete]

And here is the Pelletier that the Maco2 is derived from.

 

[popgun pete]

The Pelletier spearguns tended to be anodized in red as can be seen here; prototype guns are finished in grey and probably painted.
