Disposable powerheads are CNC machined housings that fit over several 
different types of rounds (9mm;357;16 guage;223;12 guage; and 444 marlins, 
the most destructive). A brass plug is slid in behind the bullet with lock 
tite applied to it so a metal seal occurrs. The spear point is pushed into 
the brass plug (one is made for each type of round)and   fits into the open 
end of it snugly. (some times we crimp them slightly by gently biting on the 
brass (or maybe copper?) so it holds the spear tighter. When the spear is 
fired from the gun, impact with a fish causes the spear point to act as a 
firing pin, and the slug explodes out of the paper thin aluminum housing's 
flat end (where contact with fish occurs). The powerheads are watertight 
virtually forever, and they work as good at 325 feet as they do at 60. 

 The first time I fired one on a deep wreck in Pompano, a bunch of George's 
buddies were trying to spin around to figure out what pressure hose just 
blew, eyes pretty wide!!---the sound will surprise people if they don't know 
what to expect, so you should warn people first. 


>And second, are the Ultimate guns still available? 


They are harder to come by now, but I might be able to track one down for 
you. Pat Frain (aka, Powerhead Pat) stopped making guns and lights, but some 
of his stuff is still around. They are all overbuilt, and each gun will 
still be awesome 40 years from now. I'll call Pat and see if he has any he'd 
part with.

 >If yes, where?  If no,

A 60 inch barrel can handle a much longer set of bands, hence far more 
tractive force. My 60 inch double barrel (over/under) gun is accurate at 40 
feet distances (if I can get the fish to hold still that long). The problem 
with JBL guns is that the round barrels are weak, and the oscillation caused 
by the firing alerts the fish and sets up movement of the shaft which 
degrades accuracy. And they can't take nearly the tractive force the 
Ultimate guns can (from using  much shorter bands, stretching them 
maximally). The Ultimate guns have a rectangular/box type barrel  
construction which makes all other guns seem wimpy, and the trigger system 
is as rugged as a bulldozer..
While the Biller guns aren't as bad as the JBL's , their trigger mechanisms 
are like toys, and can't take the big loads.

Over 3 miles out you can use them. Getting back in with powerheaded fish can 
be an issue. You could bring a Hibachi with you and cook on the boat.... 
This is a delicate area, so if any one on this list is in the Marine Patrol, 
I have'nt actually said I shot any  fish!!!
But all our spearfishing tech dives are over 3  miles out.  And if you are 
going to selectively target your fish dinner, so that only one fish dies 
(compared to the 1 to 10  death ratio of food fish to throwaways the 
commercial fishing industry uses to supply PUBLIX or any other supermarket 
or seafood house), then powerheading your one or two fish is the most humane 
way to take fish. They don't struggle, its quick and painless (relative to 
any commercial method), and unlike normal spearing, an injured fish will not 
swim away to die where you can't get to it.  At over 200 feet, we can't get 
involved in any real exertion, so this is the only safe way to take the 
large and plentiful groupers or hogs we find on the deeper wrecks. It also 
prevents the struggling which can bring sharks in, which could make them 
crazy enough for us to have to hurt them. This way, the mere presence of 
blood in the water will at most have them curious, but not aggressive.
