Was hoping to get a 70cm gun but it is proving elusive. While reviewing alternatives (80cm Omer XXV Gold sans reel, Rabitech 80cm, HF2 80cm,...) I noticed tha Apnea.co.uk are offering the HF2 for a similar price to the Rabitech.
The HF2 costs less than I expected but the XXV Gold costs more than I expected. Looking at the HF2, what has it got that makes it better? Lots of muzzle/rubber options (good), a modern handle & slimmer mech (hopefully better design - not sure about robustness) & that funny barrel. Does it have a rail? Is the barrel shape just a gimmick? The barrel looks fatter than normal, which seems like a step backwards to me (like Halogen house lights). What is the point of the bulges, especially the second one (surely not to mimic the look of an American bluewater woody's wings)? Might have been better to mimic the shape of the C4s but in cheaper aluminium.
Perhaps the XXV Gold is more expensive because it has a lighter, thinner barrel which probably will perform better than most of the competition.
Mr X I don't think the HF2 barrell design is stupid. The two bulbs are intended to reduce recoil in a way that,
in theory, seems to me quite smart.
In fact a band speargun has two different types of recoil:
1) a primary recoil that pushes the gun backwards: on the HF2 the bulb near the handle is intended to concentrate some more mass in the back section of the gun, same as on many of the more advanced european guns (C4, Gabbiano, HF 1). The same concept, even with a totally different design, is applied on Wong Hybrids: the mass is all near the handle.
2) a secondary recoil, that whips the muzzle up: on the Hf2, this is the purpose of the bulb near the muzzle, and yes it hymitates the wings of the american blue water gun. But not just the look of them: it hymitates the same function. The wings, or the bubble in the barrell near the muzzle, give drag preventing the nose of the gun to whip up.
One more thing to say about the HF 2 is that it must have, in theory, a very good side tracking, being the barell relatively flat: the ends near the muzzle and handle are just 25mm thick (same as the XXV Gold) instead of the classic 28 millimeters.
I'd like to check myself if the compromise really works (very thin barrell with two big anti-recoil bubbles). Live and see...
