I bought one off e-bay. Not an official boga grip but close and it was only twenty bucks. I have a dirital scale at home and I weighed different items on it and then on the boga. The boga grip was only an ounce or two off. It also made me realize how big a ten pound fish is. I don't think it is super accurat in the lower range but wht weigh a 2 lb fish. I got mine to hold on to toothy fish more than to weigh fish.
