Pro Dive trigger mech??

Mike, that is a New Zealand version of the Aussie Undersee mech. Jay Riffe used these for while in the early days of his Riffe speargun business when the Aussie's quit selling him the UnderSea for his gun.

The early ones had a brass sear and trigger which was nickle plated, but they may have changed to SS.

I would not exceed 2 5/8 bands if the trigger is brass, what used to yield, and let the gun pre-fire was the rivet that the sear pivoted on. You can scratch/file the surface of the trigger to see if brass/Bronze is the parent metal. That mech you's t to be used in the Kiwi gun called '' The Gun'' and had plastic handle and nicely varnished mahogany barrel.

Cheers, Don

Are they still sold there?

Cheers, Don

looks rather tall which is going to force a tall gun and for one the shoots only 2 bands makes little sense. why not use one of the more proven and lower profile mechs and make a modern low and wide gun? just a though.

Prodive are now out of business, one model had a moulded plastic barrel and their handle looked rather like a Sea Hornet, only with a different lower grip shape. The innards are similar to the Undersee as Don Paul says. It will do what they will do. Generally 1 x 3/4" or 2 x 5/8" bands.

Unfortunately many newcomers are brainwashed into thinking that euroguns are the "be all and end all", such that both Undersee and Sea Hornet are struggling these days. Fashion and product placement has euroguns in all the magazines, yet huge fish were taken with the cocking stock guns of the past. Shaun Adlam owns Undersee these days and even has some euroguns in his product range. The "Don" and the "Godfather" being two of them.

Maybe this one has been named after you Don. The Don Spearguns I Speargun

It has all metal parts where they count, unlike many other euroguns with load-bearing plastic triggers! Some of the plastic parts are/were sourced from o/s suppliers who do similar guns, but the superior works of the "Don" are worth the price of buying this Aussie version.

The late Don Linklater founded Undersee as "Undersee Novelties" back in 1947.

I use the undersee mech on a few of my guns and on a few of my dads. Great little mech. Pretty sloppy though, at least the version I have, the shaft can rotate quite a bit...

Here is the Undersee mech in the "Reefmaster". The gun behind it is a gun based on the "Reefmaster" which shares the same layout and also fires a 3/8" diameter stainless steel (316) shaft powered by a 3/4" band. Both guns are from the late sixties.

Very interesting pics Pete, thanks.
