what are you having trouble with?
have you watched the CD or read the book that comes with the machine?
The ATP is really user friendly. if you could be more specific about the trouble
you are having I'm sure you will have plenty of members wanting to help
Reading the manual should clear things up for you, if not, watch some videos on youtube and ask questions on these forums. Pretty straight forward detector, and questions should be easy to answer.
Watch the DVD....also there are some channels on youtube that you can pick up some good info......and then just get out there and practice.....I love my AT Pro...
