My experience with the 2500 has been just the past two months. However I believe I have this beast pretty much figured out.
All metal is fairly easy. You can just switch to this mode and let the automatic ground tracking work for you if this is enabled in the menu. The detector will attempt to keep itself in tune automatically. While searching, the detector is fairly noisy with changing volume as it tracks the ground and sounds off on even the tiniest targets. Just let it work for you. I turn my threshold down to a comfortable level so this is not too high and offensive. The targets will be obvious louder repeatable signals rather than varying volume from the detector automatically tracking the ground minerals and adjusting the threshold.
A few things to play with are sensitivity, manual ground balance, fast track, and automatic ground tracking speed (off/slow/medium/fast).
Set your sensitivity to run stable without falsing in your hunting location. Set this too high and you will get falsing. This will be obvious if you lift the coil up and away from the ground and you are getting target responses with the coil in the air. Set this too low and you will lose depth.
For easy manual ground balancing in all metal mode use "fast track"; just hold the "all metal/fast track" button and bob the coil to ground balance. True manual adjustment of ground balance pretty much works like other detectors by bobbing the coil and adjusting for a consistent threshold while in "manual ground balance" via the menu selection. You can tune slightly positive or negativeas desired. However, make sure automatic ground tracking is turned off in the menu if you want to keep your manual setting or else the ground tracking will simply keep adjusting itself automatically and your manual setting will be automatically lost.
All metal mode on the GTI 2500 goes really deep and the target ID is still active and accurate!. You can also have "search with image" turned on as well. This appears to work well down to 6 or seven inches. Below this you will get the funnel shaped image which could be smaller shallow object or a deep large object.
All in all this detector is very simple to operate. If you have messed up your settings just do a factory reset by holding the "ON" button until it resets; I believe around 10 seconds.
Anyone please chime in and correct me if I have said anything in error.

Does the Search With Image feature differ in it's outer depth ability in the Zero Discrim. vs. All Metal?
I understand that All metal is deeper than the Zero Disc. But does the Treasure Imaging able to go deeper
too in the All metal mode? Or does it have limitations that are the same if you were to switch from Zero disc vs. All metal?

From my experience it works to the same depth limitations in all metal and discriminate modes. With the 9.5" imaging coil this is a good 6 inches maybe 7". Beyond 6 inches the results vary depending on the object size from cone shaped image which could be a coin to larger than coin objects at greater depth or just a larger image at a specific depth indication. The 12.5" imaging coil can image a coin down to say 8 to 10 inches with some accuracy.
I called Garrett and asked to purchase a usermanual for my old 2500. I was told they don't have them anymore and won't be getting any in as the old GTi 2500 that I have hA been out of production for a long time. The do have it online. I can understand that. Maybe I can find one on ebay. that little manual was so easy to carry around in my top pocket.
