Hi; Why not consider a good used White's DFX. It will be the only detector he will ever need. It is a true turn on and goo detector with several Pro Programs built in and you can even create your own Pro Programs as well. I find dimes at 10" - 12" all the time. You can find a jar of coins at 2' no prob. You can even use it at the beach and go from dry sand to wet sand with zero problems. You can not do that with the At Pro. You can also buy a good used DFX for $400. Any problems with it you just send it to the factory and they will fix it for FREE ok. You can't beat that. You also can't do that with the AT Pro ok. Your decision. Good Luck. PEACE:RONB
