AT-PRO...Got this unit from Andrew at N.E.D. This unit is a overkill for what I needed for on the drysand and sometime in the wet. I'm only using it for recent drops in the summer. I needed a waterproof unit for the rain but I am sure it will come in handy for some dirt digs....Hell I think I will go back to dirt digging this week just to see what it does! I took her out today in the dry and wetsand. Ground balance both time...I dug everything just to get a feel for her. I ran it on the PRO mode...this unit isn't bad at all! Two main reason for getting this unit was as I said before...its waterproof and most importantly faster recovery time which is at! I'll be retiring my IDX-PRO. Shes been very...very good to me. I remember paying $450 for her back in 2002 and believe me when I tell you it pay for itself 20+ time over the years!
