My Garrett 250 does not work that well

[Bearprint]

When I move it over a spot with some metal underground, it says a sound sure enough, but now matter how many times I do it again, it won't say the sound again, and 98% of the time there is nothing there.

Slow reaction time? Or something else?

Where are you located and what kind of ground are you swinging over?

Many areas are highly mineralized and can throw out false signals. Also, if anywhere near salt water, apparently this can also fool many machines into sub-par performance.

Run your machine over some actual coins. If your signals are normal then your previous signals were ghost signals. As has been said certain ground conditions will cause falsing.

Swing at multiple directions, wait for that solid signal in all directions
Happy Treasure hunting

Wrap your coil cable tightly around the shaft. A loose cable can give you false signals. Turn your sensitivity down a couple of notches. Hunt in coin mode only. All metal mode and jewelry mode can drive you crazy with bogus signals.

 

[Back-of-the-boat]

Wrap your cable over the top of your shaft not the bottom, wrapping it around the bottom puts it closer to your coil.Don't know if you can ground balance or reset your settings with your machine but if you can, try that and last if you use more than 1 coil, reset machine each time you change coils so your machine can recognize the new coil.

in high mineral areas --you might get a false signal but as the machine figgers it out it will then reject it ...unless it repeats steady --most likely its a junky false signal (single beep) a dissolved rusty iron item --like a old nail that's rusted to iron dust will often give you the "disappearing" signal because once you dig it the iron mass of rust is broken up --tip look for rusty color in the dirt you dig

I live in Denmark.

It was particularly bad on the beach - I did not find a SINGLE thing although the machine emitted sounds all the time.

So... I should move more quickly with the coil? Didn't the instruction video say you should move slowly?

Your single freq. detector is sounding off on the salt content on the beach or black iron sand.

Best of luck To Bearprint. You are giving great advice.

 

[Back-of-the-boat]

Bearprint your machine should work ok in dry sand, but metal detectors work off of reading the conductivity of metal and salt water is conductive also.So if you were in wet sand that is why it was giving false signals or like others have said there could be minerals or blacksand that are conductive also and that is why your machine was giving you false signals.There are other machines for using in saltwater conditions.Yours should work fine everywhere else as long as there aren't other issues with your machine.

Check to make sure all your connections are tight only hand tighten them though.

 

[ivan salis]

note if in salt water area or high mineral soil area or near power lines -- you might need to adjust your sensitivity (power output) levels downward slightly to make the machine a bit less "sensitive" so that it will not pick up these things and give out a false signal ..but only lower it until it stops acting up ....

I hunt beaches once in awhile and have no trouble finding coins and rings with my Ace 250. Never had a problem with false signals at the beach.

I'm using a Garrett Ace 350 that I got from Things Reports | Product Reviews and Guides, never had a problem with false signal at the beach too. Always try to reset your coil that might help.

Hi-

Been using the same machine for 4 years on beeches- wet sand only- with no problem ( half sensitivity). Went out last week and my machine did what you are describing.
The cause- One of the batteries was in the wrong way! Didn't think it would operate at all with one in incorrectly. Obviously not. I wonder if other detectors do the same. Hope this helps.

I'm gonna dig in some fields soon, thanks for advice.
