Re: Taimen Pneumovacuum Speargun

I see that a "Taimen 1400" was made to a special order, this gun requiring the stepped ladder loader to charge it! That is a very long pneumatic speargun, which is a big stretch on a gun originally designed for shooting in thickets and reeds. However the long gun was seen laying alongside a pile of big meaty victims, so it was deadly in the right hands.

Using the stepped ladder loader is shown here for cocking a very long "Taimen". Note the supplementary horn on the muzzle to hook the loader bar.

Re: Taimen Pneumovacuum Speargun

A titanium model of the "Taimen" has been announced with a full titanium construction as a limited edition. The gun uses the new muzzle with an integrated line slide holder, somewhat like the black plastic nose produced a year or two back, but with a different shape to the front profile. Price of PVM600 d8- 27,550 rubles.

Plastic muzzle (now discontinued) prior to drilling of side ports in slots (always thought that this should have been molded in luminous green as an option for night hunting).

Prototype muzzle in alloy. Now produced in titanium for the limited edition gun.

The side-mounted line release lever with a return spring which can be seen in action here on the titanium gun handle.

Re: Taimen Pneumovacuum Speargun

There is a new, less raked handle in the works, but to maintain some tradition in the handle shape I think that it needs a larger butt plate as illustrated here. One advantage is the gun is more securely held if being twisted in your hand by the larger pad at the grip base preventing it slipping too easily through your fingers.

Re: Taimen Pneumovacuum Speargun

Here is a schematic showing where the various rubber seals are located in the "Taimen" gun. The "O" ring sizes are quoted as internal diameter ID x rubber ring section width SW.

Re: Taimen Pneumovacuum Speargun

My titanium "Taimen" arrived today which was very quick since my first "Taimen" took many months to arrive as it must have been put on a ship. Here it is alongside my alloy version with its rear handle removed. "Taimen" gun handles are plastic clamshell moldings which can be removed with the gun still pressurized, unlike most pneumatic spearguns where the rear plastic handles are part of the rear pressure bulkhead.

Re: Taimen Pneumovacuum Speargun

I weighed the two barrel assemblies and the titanium gun is 407 g. and the alloy gun is 330 g., so a weight difference of 77 g. Bear in mind that the alloy gun is a power regulator model and has a few more internal parts, while the titanium gun is single power and is also the 8 mm spear version with an 11 mm ID inner barrel. My PVRM 600 is the 7 mm spear version and thus has the 10 mm ID inner barrel. A true weight comparison would be to compare two guns with the 11 mm ID inner barrels. The 8 mm spear version goes up in barrel bore size to provide more force for driving the heavier spear. Note that the 6.5 mm spear version is discontinued. The titanium gun, for now, only comes in the 8 mm spear version.

Re: Taimen Pneumovacuum Speargun

Now the balance of the titanium gun has arrived, including its 8 mm diameter spear. Before fitting it to the gun body I have photographed the grip handle alongside the previous handles, the right hand grip with thumb rest and the “universal handle” for use in either hand. The titanium handle is fitted with the side mounted line release, although the space is still there for the finger guard mounted line release if you wanted to fit it.
