I bought the grip a few weeks ago with the intention of using it on my kayak and having a compact easy to use scale. The grip itself works great and i have no complaints there, but the scale part of the grip is way off. I tested the accuray on a 10 pound weight and it read at 7 pounds, so when i caught a nice striper, it only read at 14 pounds when it should have read about 20. Just save your money and get a boga, or try another brand.
I bought the 25lb. scale/gripper. I plan to use it fishing from my sit on top kayak, where a net would be impractical. I seems to operate very smoothly, but the black rubber handle smells like TAR something awfull. It is so strong it made my eyes water. Tried washing it with strong soap, but it made no differance. Thus the reason for the 3 star rating.
I bought it just because it was a cheap gripper. That part of it works fine. The scale part of it is off by a pound#... but as I mentioned, I did not get it to weigh fish. Not recommended for anyone that wants to do both.
