Small spear gun that has been specifically created for den fishing, available in two lengths, 45 cm and 55 cm.
A gun that was created to avoid having to replace, during den fishing, the use of the spear gun with that of an oil-pressure gun, with a different grip, traverse and aiming.
All the technical characteristics are identical to those of Geronimo.
Geronimo Crevasse is supplied with a 7 mm threaded shaft and has a three-point spear.
If necessary the spear can be replaced with other models or with standard threaded harpoons.
