What is the best scales to buy.Need some that will weigh maybe 15-20 lbs(if needed) and still be accurate for smaller fish like crappie & bluegills the smaller 1-2 lb range.I got a pair a rapalas for xmas after weighing maybe 40-50 different fishes and different weights they seemed to not be accurate on smaller fish under 4-5 lbs.I like to find sime that would be accurate for all smaller freshwater fish.
