Digital fish scale

I have an older Berkley digital and a rapala manual. Both are pretty good. For tournament fishing, the nod goes to the manual. It has a slider on it. Set to zero, put a fish on and it slides down to the max weight. Great in rough seas or to get a quick read.

Go to eBay and search pocket luggage fishing scale. Mine is the little blue square one. It's surprisingly accurate. You can usually get them for around 5 bucks shipped.
