Spearguns – Cayman ET

Omer Cayman ET:

New cuttlefish shape speargun with considerable mass and rigidity featuring an integrated « Enclosed Track» spearshaft guide.

This system features three principle advantages; it keeps the shaft exiting the gun perfectly strait during the shooting phase even with double bands avoiding any possibility of so called “shaft whip”.

The absence of recoil induced energy loss confers more power to the spear.

Less energy is dispersed through recoil which is a typical phenomenon on open track guns.

The shaft is no longer susceptible to lateral vibrations while maneuvering the gun.

The outcome is more power, accuracy and range than traditional open track guns of comparable size.

The increased volume of the speargun barrel allows for an optimal balance of the gun even with 7mm shafts and double bands.

This creates an agile speargun which is easily maneuverable even in the longest sizes.

– This new integrated spear-shaft guide can accommodate shafts up to 7mm. Once the spear shaft is inserted in the track the shooting line doesn’t need to be wrapped around the shaft in the muzzle.

– The diameter of the aluminum is 1.2mm in the shorter versions (up to 95cm) while it becomes 1.5mm in the longer sizes (from 105 to 130cm). This way the correct mass is guaranteed as well as the perfect stiffness of the barrel.

– At OMER they built a 8mt tube tank a bathtub for testing their spearguns.
It features two photocells measuring the speed of the shafts, considering different distances from the speargun and a special stainless steel plate measuring the shaft impact on the target. Thanks to this special tank, they have now the possibility to record all objective data to estimate all relevant spearguns performances.

– The new muzzle is designed for the use of one or two circular bands.

– The geometry of the muzzle places the loaded power bands in a low profile position that improves maneuverability and clears the line of sight. The positioning of the bands ensures a perfectly parallel band release without rubbing on the barrel.

– The Enclosed Track guns in  95cm come stock with an America 6,5mm shark-fin shaft and Power 18mm bands.

– The 105cm,115cm, and 130cm versions come instead with an America 6,75mm Sharkfin shaft and double 16mm bands.

– In the muzzle is a small compartment designed for lead weights to customize the ballast of the gun based upon the band and shaft power configuration.

The speargun comes with the spearshaft and band.
