The AT Pro is being super nice to you. Love all those rings.
I've been thinking mighty seriously of getting the Pro to try some water detecting, but most of our water has salt. Well, I do know some river beaches north of here that I can play around on. I really want to hit the big party area at the lake...got to be a lot of lost rings & of course pull tabs.
I am pretty sure it will work in salt water as well. Don't have any near me, so I am just hitting the low lakes. All I have ever had is the ACE 250, so I am loving the water!
