chaunc mentioned this a few years ago, and ive seen it in ads for ice skimmers. i was going to just mark the handle with a magic marker from a tape measure, then i remembered i had this sticker laying around, so i cut off what i needed and put it on my scoop. then i wrapped it with a peice of clear tape to protect it. main use - measuring panfish. secondly, to check ice thickness. this will be better than the little 12' tape measure i used to use.
