Just wondering if you are very carefull is it ok to dry fire a speargun say from in your boat when a big fish comes past?I just know that some people say to never dom it but i cant see the harm if your being very carefull and not being an idiot about it.Also would there be a danger in the band coming back and hitting me in the face or can i damage the spear or speargun?Im only using a smallish this speargun.
Asking for trouble IMO. I don't know why you would want/need to fire a speargun out of the water. Might be time to buy a bow and arrow instead <img src='http://www.squidfish.net/forums/public/style_emoticons/<#EMO_DIR#>/wink.gif' class='bbc_emoticon' alt='

Spearguns are meant to be used in/under the water....what next?
Slingshots, firecrackers or fire arms?
Just stirring....the pot.
Blue.
The reason why im asking about dry firing is because i have been on boats where a big fish has swam by the boat and i wished i had a speargun or bow and arrow to catch that fish.I mentioned just the speargun as i have just bought one off ebay and i was curious if it would be a good thing as i am more likely to hit that fish with a speargun than a bow and arrow which i dont own anyway.I just want to know if its dangerous to myself as i am not stupid enough to be silly with it(aiming at people or anywhere but the water).Or if i can damage the speargun or spear in anyway by dryfiring.
I think that there is a possibility of damaging the spear gun rubber, as they are designed to be stretched while underwater. Leaving the gun loaded while dry would likely reduce the rubber's lifespan.
Another problem you will face is the problem of water refraction - hitting a fish in the water, that you are looking at from above the water, is very difficult due to refraction (bending of light by the surface of the water). You would not have this problem if aiming at a fish, while you are also underwater.

If you are interested, Snell's Law describes the relationship between the angles of incidence (what you see) and refraction (the true position of the fish).

Jazman, You are a 'gun' hahaha.
No really I remember how long it took for me to get the hang of that Snell's law fact when you took me floundering.
