A unique tool to make sure you have LEGAL size Samoan Crab, Haole Crab, spiney and slipper lobster. This tool also shows the seasons you CANT harvest lobster. This will save you huge $$ in fines and will help promote conservation and preservation as well as harvesting proper size crab and lobster. This is our original idea and we call it “Bug Ruler.” Proudly made on the Big Island of Hawaii. Would be awesome to see everyone using these and teaching their friends and kids. Guessing size could come with huge penalties if you’re caught and your “eyeball size” was off.
