Classic ID w/ SAT Mod ??

[Tico]

Hello Guys
I just picked up a nice Classic ID with Mr. Bill's Mods.
Under the Sensitivity knob is a unmarked Toggle switch. Since the Classic ID did not come with a black sand switch and by research of Mr. Bills past post I have learned that the Classic ID was not able to have the switch added.
So my conclusion is that this switch is probally a Slow Auto Tune switch. I read where Mr. Bil did add this mod to a few machines.I have not used this machine in the real world yet, just playing with it around the house I really can't tell any difference in all metal responce or Disc responce no matter which way it's switched.

My first question is what is the best way to tell if I'm in sat or fast auto tune, switch is unlabeled.
What type of situations would you want to use a Slow Auto Tune.

I will be using this machine in relic hunting in iron infested ghost towns, around old homesites with lots of nails, etc.
I got the best coils with it, the 8" and the 6"

Thanks in advance
Jerry

The auto-tune all-metal mode of the Classic ID is the same as my IDX Pro, it takes a small amount of coil movement to respond to a target. And if you hold the coil motionless over a target it retunes to threshold hum sound pretty quick. The slower auto-tune mode will hold the signal longer before it retunes to threshold hum if the coil is held motionless over the target.

An example of "normal" threshold based all-metal mode is where you can hold the coil motionless over a detected target indefinately. Also you can reduce the size of the target signal by releasing the pinpoint trigger and moving the coil slightly to the side of target position and then engage the all-metal again and it shrinks the target signal so you can size up the target and see if it is a big target or small target. A couple of White's detectors that I have has this feature, a late model 5900 and a 6000 Pro XL, but they also have a S.A.T. all-metal mode that requires coil motion to respond to a target.
