My 10yo son got a Whites Prizm 2 last week as a gift and couldnt wait to hit the dirt. We did some local parks and found a bunch of clad at about 2-3 inches. I figured it would be a good idea to get a unit of my own (a little more depth I hope) and join the fun. After doing some reasearch it looked like Minelab was the way to go, but which one? I looked at the EX XS (used) and new EX2's, but thought it best to start out with less of a learning curve and save some money to boot. Can you folks point me in the right direction for getting started with the new machine? Any help, advice or pointers welcome. Thanks!
