Figured this would have already been done by now, but someone's got a patent on a two-spear speargun:

Picasso has had a double spear gun out for a few years. Although, it is an "over and under" rather than a "side by side".

LOL- those pics are great- love the 60s era frogman holding the gun.

Looks like the patent is expired- '92 or so?

The patent was issued Jan. 21, 1997

John W. Schmidt III from Palm Harbor is one of the inventors, I wonder if this is screen name?

The inventor is a good guy and his prototype has killed alot of fish. There was talks not to long ago about mass producing them to some degree but the cost was to high.

Miakka, I like your user title.

Do you guys think they're that effective for freedivers? I've never done it with a double barrel but every time I shoot a fish everything scatters, if anything sticks around the other shaft could be stuck on the bottom making it difficult to maneouver the gun, same thing if one of them little pelagics is on one of the spears and his buddies are sticking around.

What I've been wondering about is why there isn't a double-barrel pneumatic? All the bands and such seem to make a double-barrel gun complex (and honestly, I'd be worried about the 2nd spear getting the reverse-accelleration if it got caught on loose bands from the first (the over-and-under might be better to avoid this).

But a double-barreled farter should be easy- duct-tape two of 'em together? Don't we have a patent lawyer on here somewhere? I thought of it first! :circle:

I'm thinking for two fish... one for the one I spot, the next one for his buddy who comes to look..

Yes, the answer is 'load another shaft', but pulling a second trigger is faster- and we've all had the "I wish I had another shaft loaded" moment.

most double barrels are designed to be free shaft guns so i think that would ilievate (sp) your problems speareasy. And it deffinatly is faster to pull the trigger again on a second inquisitive fish than it is to reload. The double barrel pnuematic does sound interesting though.

The picasso is the most well known double, I really didn't know of any others except for a 4 spear cartridge powered gun. There was a discussion on the picasso on SB where I basically said the same thing and also that I think it's a POS. But it is designed for freedivers because it's a chest loader and freedivers don't freeshaft.

Hows this for an idea
A double barrel with one shaft on a float line and one lined to the gun.
Or you could have one free shaft and one float line.
or two floatlines.

I own a double barrel over and under, cant remember the name right now but it is factory made, the stock is rectangular aluminum, have not looked at it for a few years, it's in my storage unit, burried.

It has two separate triggerguards and separate safety.

One shaft is on a shooting line and the other is a freeshaft.

It's pretty cool and well made.

I will dig it out and try to get a picture, but I don.t know how to post it.

It went under water in Wilma and I kinda lost interest in alot of stuff.

My old buddy, Jerry Kerns who is 79 now used to build alot of guns for his diving buddies and he told me of a few over and unders he built using Sea Hornet mechs, one with the trigger on top, the other with the trigger on the bottom.

I have never seen one.

I do have a couple of guns he made in the 80's, I'll try to take a couple pics of those also. Really basic freeshaft guns.

Well, I found the gun and took some low res photos, but I can't figure out how to post them.

Can somebody give me some help.

Thanks

I have an ultimate double gun they were manufactured in fla in the 90's
alum body over and under top shaft extremely accurate

Make a normal post then click on go advanced. This will take you to another page. Scroll down a little and you will see a button called mange attachments. Click on that and it will let you browse your pc to find the file. When you find the file click on it and then click upload. Close the manage attachments window and click on submit post. Looking forward to seeing it.

hope this works, looks like it did

The gun is neat, top shaft is longer than the one on bottom, upper trigger is for top shaft, there is a safety you squeeze with third finger for top shaft, bottom trigger has a slide safety.

Handle is cast aluminum, gun is made by ULTIMATE DIVE PRODUCTS INC.,
DOUBLE BARREL is embossed on each side.

It would make a nice collectors item for a spearfishing dive store.

Went to Jerry's to get more info on the doubles he had made.

He joined SPUC in 1961 and made at least 6 doubles between 1964 and 1970.

The first he made for himself so he would have a small advantage since he said he was the worst diver on his team.

Other guys saw it and wanted one, so he made them for them. He said Ray Odor would remember his guns.

He said he had one in his shop that he had robbed the mechs out of.
He let me take it to show you guys.

He left about 1/2 inch in the center of the stock, cut on an angle so the part where the spear goes in would be in the center of the track groove on each side.

Then he put a Jerry handle on each side. Pretty cool.

To use you shoot one shaft then turn gun over and you are ready to go again.

The other two are mine, that I got from the guys he made them for.
