i have a scale that is the hook type it is digital i was just wondering how you put a fish on this without hurting it. I wanted to know if these hurt it and how you put them on it.

THanks

Just do what my Fishing Partner Ron does. We had the same scale and didnt want to hurt any fish either. He came up with a formula any fish he caught approached 5lbs any fish i caught was around 2 pounds IT SEEMED TO WORK GOOD FOR HIM

just behind the lower lip, through the slot created by the gill plate.  You won't be actually touching any gills, just the "meat" inside the mouth.  Thats what I do with my berkley digital scale.  Just take your time and make sure you get the hook in the right spot and everything will be ok.  Another trick that Low Budget suggested one time was to use a plastic bag.  Wet the inside, put the fish in, weigh it, then take the fish back out and release it.
