Hello Pico and Auto nerdz alike. I'm Joe and I've been working on vehicles the last 7 years. I started when I was 21 and I'm now 28. I started using a scope, Matco scope, about 4 years ago. It was very limited in it's capabilities but I started experiencing the serious upside to seeing voltage and current movement though circuits. I then moved up to a 4425 Pico and never looked back. I occasionally help my coworker with his Auto based oscilloscope but it always seems like it's not quite enough  ;) I have been hearing about these forums for a while but never got around to actually signing up. My purpose in being here is to learn about the vast research and put my 2 cents in when it comes to testing. I hope to interact more frequently now that I'm here. Thank you in advance for the experience and knowledge.  :D
