OK Dusty, Just an FYI..Don't know what kind of scale you have but I have a berkely 100 pound digital in the boat. It's not certified but it can be if the need arises. I have known others who have this scale and have had them certified so it can be done. Think it costs less than $50 or so to git it certified. If occasion arises again and I'm on the water, you are welcome to use it. I can always be reached on the marine radio!
As long as your scale can be certified, then you can take pic of the measurements and weights and get the scale certified after the fact. I know of other folks that have done this. No need to pay the cost of certification until ya need it assuming the scale you have can be certified.
