Stopping tournament cheaters

So long as you have tournaments, you will have cheaters. It's all about the bragging rights and money. It's no longer a sporting event, but rather a money event.  It's time we enjoy the sport and take the money out of it. Give the fish a brake. 

Aim has been doing it for years. Photo of fish on bump board, they have preweights  set based off of length of fish.

Could definitely see it; however, I'd think it would require digitally calibrated and verifiable measurements.
