I am in the process of evaluating my population of LMB and BG for culling. The fish scale I currently have is a Rapala which is accurate when weighing objects over 2 lbs. Having tested it on various weights I found as an example, a 1 1/4 lb weight scales in at 1 lb 9 ounces, while 3 lbs of weight is spot on. I would like to accurately assign the RW to smaller fish like the BGs. What do you recommend to accurately weight fish?

Thanks for your help!
