A year and a half ago I knew I was going to buy an E-Trac. It didn't take me long to realize that if I was going to spend that kind of money that I better make sure I was going to be able to learn how to use it being new to the hobby with 3yrs experience with only a Bounty Hunter Land Ranger. I did learn alot of the basic pin pointing without a probe so even with the E-Track my average Plug is no bigger than 4" in diameter. I started to print out every post that I felt was teaching me something and started a large binder. I organized it to cover every function on the Menu,puting every good post in its proper place for easy review of any subject. Its not to late, all you have to do is go all the way back as far as you can in the forum and start your own binder. You wont' have to ask the newbe question like How Do I Turn It On. Got Andy's Book a year ago and down loaded the manual a year ago and started studying a year ago. I can learn anything from others if I only listen and put out the effort. S------O I spent the money and now I own one as of last week. After only 20Hrs. on it I Have learn that If I turn it on, then I will always be learning something NEW, it comes with an unending learning curve. Go Slow and THINK or ask on the forum. HH Everyone
