Hi John, I've been seeing your posts. You do quite well for yourself and it is nice to see someone answering questions pertaining to this fun wonder hobby of ours! So you have been enjoying the ATX? This is going to be one of my next purchases in the near future! Definetly, I do tons of water hunting and use an Aquapulse A1B with pretty good success but it sure loves iron!! Lol, I don't mind it just that I wish it was gold instead!! I have a few questions pertaining to the ATX. I might use this for beach hunts in the dry sand and stuff, maybe even use it on a few water hunts. This detector will be mostly used on old house sites, not necessarily on the house site itself but around the surrounding areas. I hear that this machine will scream if there are too many nails, I have used a few VLF machines and the whole nail thing drives me nuts!! But I have found some cool stuff even though dealing with all those crazy iron stuff!! I feel there is more lying around the outskirts of these old houses but always wanted a machine that goes deep!! Thank God for the late Mr. Garrett and his awesome technicans!! So what about HOT ROCKS, they are a big problem in Hawaii. Lots and lots of mineralization, does this machine cancel them out? I sure hope so because these rocks used to register a 95 on my old Whites XLT and I always thought it was a good target boy did they fool me!! What about find caches that are mason jar size? What kind of depth would I get on something like that? I also do bottle hunting, I know it won't pick up glass but if big pieces of metal are buried with the old bottles pressumbly in old out houses would this machine pick it up deep? Well, I can't wait to hear your response. I really appreciate it so very much!! Aloha
