We used to sell a ton of stuff on ebay and had to calulate the postage. ..so we have to make sure our scales are accurate. I know some of the pictures can do both..make big fish look small and a small fish look big. Example..Buudmac's bass does not look 3 pounds but trust me it is..This is why I plan to photograph the weight. as you did. What Ii do to calibrate them is use 1 pound soup cans , 5 pound bag of sugar and a couple more exact weights and then test them on scales...so far they've all been right on . When I first got my digital scale sometimes it would not come on...that is why I bought a mechanical. After seeing your Berkley in your wife's fish I decided to get my digital it out of my storage tackle box and try it again.It worked great. Ihooked it to a 5 pound bag of flour...It registered 5 poundsI'll bring my other scale as a back up...

PS PLus I honestly know if I cheat by one ounce that God will discipline me for it."A false weight is an abomination in the sight of the Lord."
