I was trying to work that out myself, but my thoughts are the titanium has a slightly different surface finish in terms of not having the burnished appearance of the Bazovsky guns and the handle grip does not have alternative covers, but who cares about that if it fits your hand as is? If I were not already snowed under with guns being examined and tested I would buy it at only 400 bucks, plus the titanium tubing would cost me about that much before I even turned it into a gun!How do you think this Etelis compares to the other ones in terms of quality? It is obviously quite different from the ones mentioned earlier.

Safety of a Zelinka Trigger?
I have been thinking about the inherent safety issues of having a valve triggered gun but even though the Zelinka system does have a seal at the end of the barrel, it still has a very effective mechanical sear holding the barrel in place.
If the o-ring fails all of a sudden, there is still the big spring loaded bushing which the o-ring sits on taking up a lot of space and obstructing airflow into the rear of the barrel.
So, perhaps, even with a catastrophic failure of the rear barrel seal, the shaft will just be coming out very slowly without any real danger?
@popgun pete, @tromic and @Jegwan what are your thoughts on this? Do you know if the Zelinka manufacturers or users have tested this?
The Zelinka trigger is one of the most "reverse" triggers we can fit in a pneumatic speargun, hence my newfound interest in it. The Taimen trigger could be positioned quite far back but will likely have more friction. Also, a Zelinka system doesn't need a piston with a metal tail on it so can be made very light and short - which should give much better durability and a bit of efficiency.
The "reverse trigger" nature and the efficiency and durability of the piston makes it an interesting candidate for an optimized, high pressure gun.

Just a little P.S. for you Gecko:
Yes, true, but I believe that a further development of the design on Hydropneumatic guns could be your answer to a "no compromise" really high pressured speargun.
Zelinka guns are expensive to make as there are many more moving parts. Often they have no trigger safety, in fact no safety at all. But what they can do is use the power regulator to restrict the releasing valve opening so that the spear is ejected with little force by throttling the gas flow. If you consider the "Alpha C1" which is a valve operated gun, but not a Zelinka, you can shut the firing valve down so that it cannot open at all and the gun cannot shoot. The Italian valve operated guns the GSD “Dynamic” and “Katiuscia” all had a sliding safety device inside the trigger finger guard space which locked up the trigger.
