    A solid product that can provide very accurate weight estimation if you follow the directions for additional girth measurement. I have found that storing this loooong ruler in its original packaging is helpful with storing it in your boat. Because I lay this over top of tarpon I chose to trim the green tab off at the zero mark for easier, accurate measurements while minimizing the time at the side of the boat for the fish. This trimming of the ruler is unnecessary in my opinion for other release rulers such the one for bonefish. Ultimately its your call, but for me its been helpful.
