Boga Grip Advantages The Boga Grip is designed to promote "catch and release fishing," as it will land, handle, and weigh fish quickly and simultaneously without injury to the fish. The Boga Grip also affords an easy opportunity to inspect and take pictures of the fish. The Boga Grip is particularly good for handling fish in cold weather, or hard-to-handle fish such as toothy fish. It also keeps a fisherman's hand at a safer distance from hooks. Boga Grip Design The BogaGrip is generally tube shaped, with one end serving as the grip and scale, and the other end with a pair of jaws. It has a trigger sleeve that slides along the main tube, serving as an opening and closing means as well as a lock. The grip consists of a sleeve tube covered with a non-slip grip. The main tube has a precision scale embossed in it to match each individual scale spring, and the scale is calibrated using certified weights to insure accuracy within one increment. Boga Grip Materials The BogaGrip is made in the USA of USA-made materials. All metal parts of the BogaGrip are made of 300 series stainless steel, except for the precision scale spring, which is 17-7 PH stainless steel. All plastic parts are made from acetal, which is a high-performance engineering thermoplastic that is used in unlubricated bearing applications. Acetal is tough and resilient and is very resistant to UV light. Constructing the BogaGrip of these materials makes it very strong and resistant to conditions encountered while fishing in fresh or saltwater.

In use, the fisherman will hold the grip sleeve, and using his index finger or thumb will pull back the trigger sleeve, which causes the jaws to open. The fish's weight is checked by reading the point that the main tube's embossed scale has been pulled down to inside the grip tubing. The fish is released by pulling back on the trigger.
