hau is right in that not all muzzles fit all guns. Beyond the tube diameter it's a matter of how well the track on the muzzle lines up with the track on barrel.
Jeff, what's the price of your 3 and 2 band muzzles?
I believe the Aimrite is $40.
I'll try to make the Pursuit muzzle available for $30. I'll start studying which spearguns it fits.
I'm not sure how it mounts on the Rob Allen handle, but those of you interested can look into it more.
I Like the new Aimrite muzzle as well. Although I would prefer that the slots not be cut for the wishbones.
Same here. But you're running into the problem where a larger percentage of speargun owners don't tie their own bands. Wishbone inserts like these will allow such users to deal with lack of slots in the band holes. The problem is that selling a band with wishbone inserts will make it too expensive.
The Pursuit muzzle will take two 20mm rubbers.
3 band muzzle is a whole different story, there are few of those on the market.
I have to think about it. I believe and some of you guys concur that this video has good potential, maybe partly because it hasn't been done this way before.
Yeah, click on the picture 
I second the new Aimrite, I think it's about as good as it gets for a conservative guy like me. I'm trying to get it copied.
I don't like Hammer Head muzzles. They look good in marketing pics but when you get them in your hands they look and feel cheap. Other muzzles do just as good a job keeping the bands inline.
The Pursuit muzzle is a nice open muzzle. It has a modern look but is practical and without frills. It has a few unique features; it's minimal in size, the shooting line can be wrapped to either side depending on where the line release is, and it incorporates a solid but unobtrusive line anchor which at the same time serves as a line guide if using a reel.
Tin Man muzzles are simple, practical, and well made. They're the only pipe gun muzzles that incorporate a spike. The line anchor on them is probably the strongest around due to the special way it is mounted.
Thanks Bill, I know that was a lot of work.
Good idea, done.
Thread moved to the suggestions section.
Yes, ray meat is like that. I deleted the record because I remembered it has to be one person who lands the fish, and both of us did it.
Yes the housing is available separately from Pursuit.
I don't know if there's enough material on the frame of the Aim mask to accommodate the installation. This is something I'll need to look into once I get more masks, or if you want to bring yours by we can try now.
This is the installation hau is talking about.
The new lens fits perfectly in place of the original. It's impossible for it to fall out. It's rated to the same depth as the Gopro housing. It's very easy to install and take out, simply unscrew the small screws with a Phillips screwdriver, but I wouldn't recommend doing it too many times for fear of stripping the screw holes. The new lens has a disadvantage in that some resolutions that are useful out of the water have a vignette effect, see the video I posted. If you must use those resolutions for out of the water filming, and the vignette effect in the corners is not acceptable, then I recommend to buy another Gopro housing rather than be switching out lenses. A new housing is $40, and you'll have an extra lens from the first housing.
No sealant necessary as the screw doesn't go through the skirt. All you need is the Gopro tripod adapter and matching bolt.
that means that if i buy a new gopro now, it automatically comes with the new lens already mounted ?
No, Gopro as of yet doesn't have a solution. I am a dealer for Gopro, and sell a replacement flat lens that solves the focus problem. I'm currently offering an introductory deal on the Gopro for $259 which is the normal retail price, and I include an additional lens which is the flat lens (the lens sold separately is $42). All you do is unscrew the the screws that hold the black piece down, replace the lens, and tighten back down. There is no vignette effect in the R5 setting which is the best setting for filming underwater, it has less of a wide angle than the rest so things don't appear too far. This is what the housing looks like with the new lens.
Here's a video Greekdiver shot with a modified Gopro housing. I've seen the original unconverted footage and it's good enough for DVD.

Guys who want to participate should have some knowledge of working with digital video. However I would not expect any editing, only raw footage. All you have to do is make sure the footage is good/interesting.
Wishihadgills, a beginners angle on spearfishing would be a great addition I think. As long as you don't put yourself at risk by multitasking.
Don, I was counting on you It doesn't matter if the video is shot with the Gopro or not. I'll have to make the quality match though, can't have a high quality segment making everything else look bad. I don't know anything about contracts for this purpose.
I don't feel like a $300 camera setup gives me the right to ask for ownership of really good footage. But I can't put more into it financially, and I would want to be reimbursed for the money and time I put into editing and production. Posting the segments on youtube may or may not get in the way of that, so I don't know. Anyways this is just to gauge interest and a little early to talk about such things. It's just an idea for now.
BTW tinu the gopro underwater focus problem has been solved with a flat replacement lens.
I agree with you that good content will more than make up for a little lesser quality.
When you say time frame do you mean how long the participants will have to compile the footage? I would think at least one diving season, which would mean only summer in some places, and summer is already over. In other places it will be dependent on what time of year the vis is best. I think realistically at least one year.
An ambitious project occurred to me, putting together a spearfishing video comprised of footage from our members all around the world. I'm thinking 6 different members/locations. Each participating member will receive a Gopro HD camera with an underwater lens, which they get to keep, a $300 value. Each member will be expected to come up with about 10 minutes of underwater hunting footage, and about 5 minutes of dry footage; launching a boat, preparing for a beach dive, saying something about themselves etc. This will add up to a video about 1.5 hours long, most spearfishing vids are under an hour. The success of this depends I think on whether the Gopro camera video quality is adequate for a professional DVD.
What do you guys think? Who's interested in participating?
Well done Roberto and the Puerto Rico freedivers.
Thanks for the info. I merged the two records and Ryddragyn has the bigger fish.
