When you push the switch on most Ground Balanceable detectors

Do they go into all metal mode if your in disc mode ??? For proper GB .

t-2 is the only one I've used with gb and I think it stays in disc. I would think to have a proper usable gb it would have to be in the mode you're going to hunt in.

The way I understand Ground Elimination Balance to work in the whites world is it used non motion mode which is non discrimination mode. This makes sense because they are measuring the VDI of the minerals in the ground and then removing those VDI from being resounded to. To test ground balance on a whites, you lift the coil up to waist level, pull the trigger to put it in pin point non motion mode and lower the coil to the clean ground. If the GEB is correct the threshold sound will not change.
How each company does this is not the same but the reason for GB is to prevent the MD from responding to the minerals in the ground as if they were a target. After all they are iron based and magnetic or on a salt beach they are salt based and conductive..

if that were the case i would think that you would only have to ground balance if you were going to hunt in all-metal. that may be the case with the t-2 because i rarely ground balance mine and i seem to do fine when hunting.

In white products the All metal nonMotion is what the motion discriminate run on top of.. without non motion there would be nothing.. Ground blance is ground balance in either mode.. Make Machine ignore the ground VDI. If you location has low mineralization then once set you would be good to go.. If you have auto trac and it is on, then it will maintain the setting as the ground changes..

Your right Chuck..The T2 works well at preset 90 GB, and , is actually better if you can't get a good GB due to trash in the ground.
