Ive been playing with my new Pulser I purchased and was trying to find some YouTube videos or something like that to see how it is done in real time. I havent found any videos online, that shows how to use it properly. If anyone has any links or anything I would greatly appreciate it. Also, is it possible to locate valves with the pulser as well? I have a 521 locator but was just wondering if it was possible to use the pulser in a pinch.
