All my spearguns are now equipped with the latest models from ERMES. I am in regular contact with ERMES and I make you benefit from the latest innovations. I particularly use two models from ERMES. THE FUTURE DOUBLE ROLL VERSION and the DOUBLE-ROLL WINGS with the trigger shortened at my request by ERMES and specifically for my spearguns.
GLADIATOR MECHANISM :
I also make my own mechanism. These are reserved for my old customers used to the mechanisms of my production
ERMES FUTURE DOUBLE ROLL :
This mechanism mounts the roll system combined with another roller that interacts with the trigger, with operation in a gear ratio, thanks to its innovative interior components (patent pending), this system allows to have a sensitivity on the trigger unthinkable with traditional mechanisms to very high loads (maximum of 0,500 kg trigger operating force of traction of 300 kg !!!) with a virtually unlimited length of the shaft coupling component.
ERMES DOUBLE-ROLL WINGS :
Ermes Double Roll Mechanism for wooden speargun builds is 100% handmade in Italy. This mechanism utilises the Roll system, combined with another roller that interacts with the trigger, thanks to its internal innovative components (patented).
