It's good to see 'retrosubs' group will be growing .

You know Ive even heard that some make their own guns!!!
Can you believe that?

forget the laser sight, what about guided spear? Solves the problems all in once...

Maybe someone could make a rail for the spear to travel on while in the gun?

[Murat]

that would be great.

I will inform you first, and put to the top of the list when i produced one.

you can make a laser sight for a speargun easy enough. just buy a bb gun laser sight (daisy makes one thats more than good enough for speargun range) and enclose it an a miniature o-ring sealed glass tube (similar to the housing unit for underwater cameras). if you have a pneumatic gun you can attach it to the top of your gun, if your gun is band powered then you will either have to mount it on the very front of the gun (tricky), on the side(s), on the trigger mech, or come up with something very creative. either way, i would view it more as a training tool than as a permanent hunting device...but who knows. let us know how it turns out.

As one who doesn't even take a scoped rifle when he goes to Africa, I find this thread a little outre'. What are we headed to, GPS guided arrows on deer? Though I have great admiration for technology, some of its uses are a bit fluffy-headed, IMO. The next thing will be "Why don't we build a fishing lure that goes down and grabs onto the fish, then hauls it up into the boat and fillets it right there?" Grump, grump, grump!

I find it hard to take this thread seriously, but I can't resist one comment.

Many spearguns don't shoot where they are aimed. A stock Riffe Island, for instance, shoots very low because the gun has insufficient mass for the weight of the shaft and the thickness of the bands that it uses. So it recoils, the gun rotates around the handle where the shooter is resisting the recoil, the muzzle rises and pushes the rear of the shaft upward, causing it to be low right out of the gun, even before the effect of gravity.

If the laser sight was aimed right down the axis of the gun, you would miss. I guess you could crank in some elevation in the sight, but how much for which range?

I dont think the light would work but damn if yall havent once again figured out whats acceptable and whats not....you should all use pointy sticks because slings and polespears are too much tech. Dont even get me started on your fancy smancy teak guns with extreme triggers able to hold hundreds of pounds of fish impaling force....

Pointy sticks, eh? Maybe for you, Mr. Modern-age. I'll just stick to sharpening my fingernails.

Also, I prefer to close my eyes and use the Force.

while we're taking all the fun and challenge out of spearfishing, maybe we should have lazer sights, and electrical shafts that stun the fish even if you miss, how bout hunting on scuba too, Oooo Oooo or CCR's!!

yeah, because their is sport in that

a mask, fins and a conventional speargun/pole spear kill fish just fine and make it sporting. why screw with a good thing?

[Mattedhead]

I'll stick w/ my jon-boat, a case of cold Budweiser, and a sackful of dynamite...

If it requires batteries...it better take a damn nice picture, or shine a little light on a bug, otherwise leave it in the boat!!!

I think the laser sight idea is a cool one if it would work. Its main problem would be tracking moving fish .. as you need to 'lead' or aim ahead of the fish and your reliance on the visual dot would then be a hinderance. But even better is the suggestion of a torch. I have recently ditched wearing sockies in an effort to reduce the amount of kit and kitting up i find myself doing lately so having a separate torch for under ledges and in caves would be a definate no no.

I have freedived with competition divers in deep dirty water who have tied a small torch to their mask straps which comes on with increasing water pressure and goes off again with decreasing water pressure. No fancy pressure switches though. They unscrew the torch head until the globe contact only just stops making contact with the battery. At some depth the water pressure pushes the torch face inwards against the O ring and contact is restored and the light comes on. Considering the time spent under water a few batteries should last easily the day.
No switches and auto on and off. A simple bracket and fix to the underside front of the gun and it illuminates and possibly shoots where you shine. Alternatively leave it on the mask strap and it shines where you look.

This must work.

Ok...A few years ago underwater red laser pointers were for sale on ebay for £10..

I strapped one to an Cressi SL100 and went out into the water at dusk with great hopes and anticipation...Oh how wrong I was! A laser sight on a spear gun is about as much use as a cat flap in an elephant house.

To point things out to students, now thats a different thing but for hunting I would just stop watching the films and get back to the real world. Spears dont fly true, a red dot is bloody hard to see in kelp or weed and the last thing I need is another usless toy! And thats my two cents.

useless gizmo, but I'm sure some rookie will get sucked into buying one

I'll 2nd that. And add that practice on shooting skeet with a shotgun, out of the water, is an effective way of getting better shooting moving targets.

I have a green laser pointer and a friend has just suggested to make it waterproof. I think it is stoopid. We dont need/want all this extra kit.
If he does do it I will let you know.
BTW anyone speared in Gran Canaria??? I need info!
