2500 in all-metal mode
- Thread starter Bum Luck
- Start date
The True All Metal mode goes very deep. If the ground you are trying to use it in contains a lot of metal it might be very difficult to tell where one target begins and the next one starts. I use the mode every once in a while especially on cornfield (relic) hunts in the Spring and Fall. It is the only time I ever really dig iron.

Define signal definition. Are you running with your threshold high or turned down low or off? Is your sensitivity set high?

The true all metal mode only gives one tone audio signal, so iron and silver sound the same. However, what you want to hear is a nice clear signal, an indicator that it could be a good signal. The cursor will appear at a probable conductivity below the various icons on the screen. Anything in the coin areas definitely needs further investigation.

I'll try.
I'm running with factory settings, whatever that setting is. Sensitivity is around 7 or so.
Instead of being able to pick out a target, it seems difficult to tell what is (or where is) a target. There is sound most of the time (of course, trashy areas are going to be busy), but it is still tough to tell when I hit the edge of a target. It should sound more like the pinpointer.

Bum Luck. I have a GTI 2500 and have used it a number of times on the Australian goldflieds and our beaches in AM mode. I have 25 odd years of experience and really know what I am listening for so I find it very easy to use. Not sure how much experience you have but a suggestion would be to play with it in a relatively clear area with test targets and listen at differing heights and target sizes etc. Learn what to listen for as far as a metallic target is and ground noise. It takes a while to get the hang of "tuning" your ears to the sounds. You should have your thresh hold so you can just hear it, not too load and not too soft. At this level it will be obvious when there s a target in the ground.
You can use it in two ways in AM. Auto ground balance and manual ground balance. You can set the balance speed in auto GB as well from slow to fast. In auto balance the machine will automatically balance itself to the ground conditions until you get an even noise from the machine when swinging the coil. It is paramount to your success that you have an even balanced thresh hold noise to hear the faint small or deep targets. When it is balanced you should be easily able to distinguish a target in the ground as there will be a definite change in the thresh hold noise. In auto balance, if you get a signal in the ground and you run the coil over it a couple of times, the machine will try and track (balance) the target out. This will mean that the balance will be out on the surrounding ground and will need a little time to re balance.
You can run in manual ground balance if the ground is not too mineralised. Over here that is almost impossible as we have some of the worst ground out for detectors. Same deal with the thresh hold.
Hope this helps and HH.
