Invest in a bump board. The judge is only 40 bucks, and used in tourneys all over North America. The problem with tapes is they are never accurate. I got checked one day, had my one over. One of the others was under by 1/8”. He used a tape, said your over. Pulled out the judge, checked said nope. He thanked me and said he was ordering one. Bump board is easier on fish, if your into the master angler program it’s easy for the picture requirement, and there’s no guessing with the judge.
