Not sure what patents could be in play as all these guns' basic design is decades old by now and has been shared by numerous different manufactures for pretty much as long.Saw that at a recent convention and wasnt too impressed, reminded me of a hybrid speargun. It Maybe a good short range gun.
My understanding of modenr guns not using a standard dry barrel is because of an old patent issue.
Hello Pete,Here is where I bought the "Shotgun" and they have other sizes in stock. The prices seem low, but this may be to sell them off.

Hello Pete,We are out of the spearfishing season now with grey and cold days, so I will not be shooting the "Shotgun" (or anything else) until September at the earliest. Quality wise the gun looks very good and really it is a makeover of their “Caccia” which is also an 11.2 mm inner barrel ID speargun. The central nose cone is somewhat curvier than shown in the photos, so Seac-Sub made some later changes to the gun. I was really surprised at how well it floated even with that narrow front section. The gun will have a higher compression ratio as a consequence (due to less tank volume), but unless you want to lean on the hand pump to use the highest allowable pressures it should not make much difference. The swing and traverse should be improved, hence in that respect the gun will be advantaged for that type of shooting where fish are quickly moving around in front of you and you have to pick one out. My “Taimen” is good for that as it has a very narrow tank of 28 mm OD, the front section of the “Shotgun” is 25 mm OD.
However when cocked to shoot the gun is going to feel more nose heavy, but that would not be a show stopper. The original Mares "Cyrano" suffered from being nose heavy, but only a relatively short nozzle meant the gains in swinging were not so great and in my opinion were not worth doing. In the "Shotgun" the intent is to make a bigger change and gains in one area are always offset by a loss elsewhere.
Thanks Pete, great comparison. I have a better perspective now.Here are some photos of the "Shotgun" 90 cm, a Sporasub "Stealth" (nee Mares "Spark") 85 cm and a Mares "Ministen" taken earlier when the weather permitted.

You can see from the photos that the "Shotgun" loses a big chunk of tank volume and has a tank only a bit longer than a "Ministen". However for the selling price it seems a good deal and the 115 cm is only AUD 132 before shipping (about USD 91.50). The spring steel stainless shaft is 6.5 mm and has an integral tip, so not ideal for rock hunting and more suited to shooting zippy fish in the water column.
