It's not very often, but every once in a while I have a good idea and I figured this was one might be worth sharing.
If you're like me and find yourself stapling up dogs fairly regular, I'm always concerned about 10 days later when I take them out that I've removed them all. Seldom is there the same number to take out as the dogs will pull a couple out, scratch out or whatever and last thing I want to do is accidentally leave one in and it become infected.
My young son is all into metal detecting around our property and a while back I bought him a cheap pin-pointer from Harbor Freight to use when digging his holes. I've discovered this to be quite useful...just run it around the area and it will alert if a staple is still there.
Here's a link.
