Tejon Ground Balancing

The best advice I can give you is try GB by pulling trigger to "fast retune" all metal mode. The AM mode on selector knob is "slow retune" this makes GB a little weird. Give it a try it works great for me. I just balance until I have neutral to very slight positive response. Good luck!

What your talking about is how to "Power Balance" the Tejon.
Its a way to ground balance in discrimination mode, my brother Ron (forum member WV62) has been experimenting doing that. (I've not had a chance to get out yet and work with it)
Do a search in the Tesoro group forum here for "Power Balance" something should come up.
I know the one over looked part of normal ground balancing is to listen for the tone chance as you "Lower The Coil To The Ground" and not as you lift or raise the coil (motion going towards the ground ONLY)

I seen the post on power balancing that Monte posted but I am talking about regular ground balancing. Do I need my threshold to sound the same from the air to the ground or do I need the threshold to get a little higher 2-4" from the ground which is a little positive I think.
88junior said:
When you push down and pull up on the coil the sound should be neutral. No louder when you push down on the coil than when you pull up on the coil. If the tone gets louder pushing down, it's positive, turn your ground balance knob counterclockwise until it's neutral. If the tone gets louder pulling up, it's negative, turn the ground balance knob clockwise until it neutral.

Just a note for standard GB by the manual, I have noticed that the Tejon needs some warm up time. You can walk out into a area and turn it on and GB it and using the PP toggle seems to work best. If you wait about 5 minutes and GB again in the same spot I am now about 1/4 turn to the positive. So when I remember I turn it on and let it run while I get ready putting on my gear. Seems to be pretty stable after the few minutes of warm up.
When I have little time I will post what little I know about power balancing.

Think of Ground Balancing control knob as a volume control on a radio....... The ground Balance control being the knob for threshold hum back ground volume control.
When you lower and raise (Bobbing) the coil up and down if the Threshold sound gets louder going down toward the ground turn the knob down (Lower the sound) if it gets lower in sound turn the (volume up).
Do this while bobbing the coil up and down till you get no or very little difference in the sound as you raise and lower the coil. If you want a little positive then turn knob up on the down bob till sounds just raises slightly..
Please remember a bad ground balance has a huge impact on depth of detection. A positive Gb does not work in all soil conditions.
Only lower the coil to about 1 or 2 inches above the ground. DO NOT TOUCH THE GROUND.....

Junior i talked all about this remember.Go to clean ground only to practice.Pull trigger back in fast retune.if you have minerals,you may need a DD coil.If you have minerals the concentric and Tejon combo will be tough.Get the threshold,pull back on trigger ,slowly lower the coil to clean ground only.If tone increases,cut GB a little left.If tone decreases cut a little+.Get a steady as you can as you lightly pump the coil.
You might find a video on the Tesoro website or somewhere in Internet land. I personally get a kick out of these types of posts because we got manual Ground Balance detectors introduced in '74/'75, and by the latter 1970s and unto the early '80s, almost everyone getting into the hobby, with even most lower-end models on up, had to understand "ground balance" to get their detectors to work.88junior said:
Then we shifted from simple TR's to more motion-based models and with Tesoro's Silver Sabre introduction in '83, we really saw a big trend in motion-based detectors with a factory preset GB. That's thirty years of so many hobbyists using simple preset models, or some of the automated GB models over a dozen yeas now, so what used to be a must-know/common-understanding tuning method we have to explain now. It's almost a backwards approach with the way we have modernized so much in detector electronics.
Then we have to remember that each manufacturer develops their detectors a bit differently and we need to be aware of those differences, model-to-model, too, in order to get the best workable GB for the mode used and site to be hunted and type of application. So, with your Tej

OK I see what your saying Mark I didn't know if I needed to keep the threshold the constant same sound from taking the coil down to pulling it up from the ground. SpiritRelic the 9x8 coil seems to handle my ground conditions pretty good so far but this may change from one site to the next you post videos on You Tube could you do one on how you ground balance your Tejon?

Tejon is such a high gain detector.This is what i am trying to explain.It would be nice to start out with the Tejon and a 5.75 DD.The high gain of the Tejon and the stock concentric is raw power waiting for a accident to happen.I don't really think Tesoro should sell such a powerful detector like the Tejon witha 9x8 concentric coil.They should sell the Tejon with the 5.75 DD.Too much power.All i can say is get to some good dirt and practice.Minerals,red clay,Farm area dirt with iron.I would just leave my GB were i had it on last dirt before trying to GB over contaminated dirt.If you GB in the operating mode,this is slow retune,this slow retune speed makes it even worse.

Well, I have a Tejon and so for I really like it with the stock coil, I also have both of the smaller coils (WideScan & Concentric).
Now, your right about it having extreme gain, but the only problem that gives me is if there is any metal above Iron and minerals the Tejon will hit on it, and it don't seem to matter how SMALL the target is.
Now I like it doing that in one aspect because not much of anything gets by it, but, it can be annoying digging and sifting the dirt to fine what looks like a finger nail clipping of metal, or buckshot, LoL.
