Wet Sand settings for ACE 250

[Beach cruiser]

What settings are optimal for scanning in wet sand with the ACE 250? I have tried experimenting on differnet levels but still get a ton of false readings. I feel I am missing out on a lot of targets by not getting the beach when the tides on its way out.

Also, how do you calibrate the 250? Is it necessary and how often?

Thanks BC

Set the sensitivity to 5 bars and knock out the bottom 3 notches. It will stop 90% of the falsing like this. You will get only half depth in wet sand (normal for a VLF detector) and the coil doesn't like waves crashing over it.

To calibrate your machine just hold down the power button for about 10 seconds. You will hear a double beep and that's it. It will return your detector to factory settings. I do my 1350 every time I change the batteries.

About the only thing you can do is crank the sensitivity down and keep the coil off the sand an inch or so. Salt after all is a mineral and the 250 has a factory preset ground balance that isn't conducive to high mineralization.

Yeah it's like rebooting your computer. I was going to mention that but I thought he might be talking about factory re-calibration.

If you want to hunt the wet sand it is time to get a new detector like a sea hunter or infinium because the 250 just can not stand the minerals in the wet sand. I tried mine and i just could not make it work so i bought a sea hunter and i love it in the water and wet sand. The 250 is a killer machine in the dry sand and it can stand up to any detector on the market but it has its limits and salt water is one of them.The Ace 250 is my preferred metal detector and i use it most of the time but when i hunt the surf i have to use my sea hunter and yes it is a PI machine so i did alot of trash but it will work in the wet sand and water with good depths but the 250 i found that i could not get no more than 4 inches in the wet sand and notching out the first 3 nothches i still got false signals.Just my opinion and maybe someone else has figured out how to use a 250 in the wet sand but i could not.

Hello from Byelorussia!!!!!!, hello of colleague!!!, my finds in this season ACE 250 :







Continuation follows.

hi,i went to the beach today with my ace 250.dropped the sensitivity down to 3 and tried diff settings.total waste of time.just kept getting false readings.the ace dint like wet sand.came out of wet and in dry and straight away a few coins

Hello from Byelorussia!!!!!!, hello of colleague!!!,
On a beach works well, put into water of vs normally.

Topman. Set your sensitivity to 5 bars. Knock out the bottom 3 notches of your discrimination, as this seems to stop the Ace from falsing. My best guess for this occurring, is that the minerals in the ground must be reading in that low range, kind of like notching out pull tabs. The Ace hates waves crashing over it and will false conically when this happens.

I have a guy telling me that the ACE250 has ground balance and you reset it by turning it off then on again and he say's it is not a preset machine here is what he is saying rented one just to check it out when we last discussed this and I thought you read what I found. I guess not. I also contacted Garrett about the ground balance. Right on their web page for the Ace250 is says the GB is automatic but I guess you don't comprehend that.

It DOES have ground balance but it is adjusted when you turn the machine on. So, if you turn it off, you can rebalance it for the conditions by turning it back on again. Oh, and I am an electronics design engineer with metal detector and embedded control design experience And he goess on to state Please tell me you don't really believe that the sensitivity adjustment compensates for salt water mineralization. All it does is hide it by making the detector less sensitive, not compensate for it. The ground balance does the compensation and that is the topic at hand. You've never even believed your machine had ground balance. Why not try what I have suggested just to satisfy your curiosity if nothing else. You don't even have to come back here to describe what happened. I'm not really all that interested in anything else except to ensure that the new user find this tip helpful
