just a note for you Joe .....
I was having yor exact thoughts the end of last year ....My ATP found me 30 silvers, mostly from one property. over the winter I kept watching the youtube videos seeing people pulling coins from 10 or 12 inches deep, and thought thats why I can't find more silver, I need more depth. (Even though my ATP had found me a few coins at 10 inches).
So, I did get the CTX this year and I have found a few more silvers, and yes it is my preferable machine, and since my GF lost her job I really wonder why the heck I spend "car" money on a hobby toy!!! The AT Pro is a very capable machine, it proved its self to me last year, and you can take a look at my album to see last years finds. I've done a lot better this year, but I've spent ungodly more hours out there digging too.....
A month ago my friend (ATP) found a walking half from an area I thought I had covered with my CTX. Last week, another hunt guy with ATP digs a signal I just passed up on, it was a merc. anyway , just sayin....its an expensive toy. I've had 4 detectors inside the last two years. I rate the ATP a 7, the CTX an 8 or 9. A strong suggestion to someone thinking about CTX would be have a serious look at ETRAC. I sold my ETRAC a bit prematurely I'd say. My friend who is using it now has 73 silvers with it since this spring!
Hes picked off many silvers from spots I just walked over, and I've seen him dig some 11 inch targets!!! ETRAC is the exact same machine as mine, minus watertight box and gps which I've used once.
Just food for thought.
