Get You one of these. You can buy them online for around 30.00 and they are honestly very nice and certifiable. They will weigh fish up to 110lbs. Blues told me about them several years ago and Txmedic033 told me where I could get them certified. All the info is in this pic and the address to a place where you can send them to and get them certified if you want is at the bottom on the certificate. They charged me 40.00 to get em certified which was pretty cheap.
