Speargun Museum Turin on-line

This on-line museum has photos of many pneumatic spearguns which over the years have been discussed here and is definitely worth a look.

All propulsion types are listed, the spring guns and pneumatic guns, including some hydropneumatic guns, are presented with good photos of models in near new condition. Mainly European models as can be seen by the absence of larger timber band guns and carbon fiber guns.

Re: Speargun Museum Turin on-line

One of the more interesting spearguns shown is the hydro-elastic SOS "Ringo” which for a time was distributed by Scubapro. The gun was in a sense a hydropneumatic gun, but instead of pressure being applied to the water inside the gun by an air reservoir via a moving bulkhead or flexible membrane, this force application was made by a stretched "Vulkollan" bladder. "Vulkollan" is the brand name for a polyurethane material which in a sense operated as a radially stretched rubber band to store the loading energy, the gun requiring two loading strokes as it uses a valve type trigger mechanism much like the hydropneumatic guns using the same principle. The small pistol-like version used 6 loading strokes to achieve the same loading result as all the guns use the same size “Vulkollan” bladder.
A problem with these guns is the “Vulkollan” over time falls to pieces and a replacement would be virtually impossible to find. These guns may look like pneumatic guns, but they don’t float after the shot.
