Not sure if any of you have seen or heard about this. Power probe, It's more usefull then you may think. I've owned and been using one since they came out. They now have a better line up of different models. If you search online you can find them pretty cheap. Just wanting to let some of you know, since investment of a few bucks can save alot of money from not bringing it to a shop. Check out there video!! Power Probe, Inc.
