I could ask this on any of the forums but feel like you Tesoro swingin folks around here are about the best of the best. I like the way you all give answers,opinions,etc. and tell it the way you see it/the way it is & not telling things in a way that you think others want to hear it. You would think that in the almost 30 years of detecting and all the wheelin & dealin I have done that I would have a test garden, but I don't. Theres no rhyme or reason why I am asking this, just something that popped in my head in my winter bordem I guess. I am thinking that you's with a test garden will take your detector out to it, ground balance your detector neutral or a bit positive and swing over your varied depth coins and say yup this detector hits this this and this and that detector hits this this and not that. I was wondering if any of you go a step farther and set the ground balance at different settings and then repeat your swings at the test garden, I guess what I am wondering is that all these years I have read/been told,etc. to have your ground balance right on or a tad bit positive for best results and I was wondering if this is completely true. Have any of you had better results/depth with any other ground balance settings, such as a little negative. P.S. I think when the ground thaws I will make me a test garden, remembering where things are will be the problem.

Test Garden/ground Balance Question
- Thread starter SkiWhiz

I have not put in a test garden either. I think Monte has covered pretty well that many of the Tesoros, as opposed to ground balanced neutral in all metal, will do slightly better in discriminate mode when the ground balance is set just a little negative in the all metal mode. Think I saw some videos posted showing that and power balancing with a Vaquero. Have done enough field checking with the Cibola and Tejon to feel very confident that those two are a little deeper in discriminate mode when set slightly negative in all metal.
As to:
Well one of my coworkers says that once you get to be our age you get the CRS syndrome .... Can Remember Stuff. So draw a map of the garden with measurements (and make several copies filed in multiple locations so you can always find one of the maps). Then make sure you realize the map is of the test garden and not of a buried hoard that you need to dig up. (My wife would have a lot of fun with this one and what I can't remember!!!!)

I've wondered that as well. Hope we see some I tried it answers. Sort of in line with this thread I recently read where a machine with manual ground balance may actually detect deeper in the ground than in the air if it is balanced properly for the ground in question. I've seen from time to time claims on some detectors for better depth in the ground than the air and always thought no way, but now I'm not so sure. It's certainly true that a properly balanced detector will go deeper in the ground than one that is off.

I do have a test garden (quarter, dime, bullet, flat button at different depths) and yes setting my Tejon a little negative allows me to hit the flat button at 8", the bullet at 9", and the dime at 7". However, I found I get better results in places with less mineralization, by setting it neutral. Doing the all metal thing to find an area to ground balance I'll sometimes find a signal that I cannot get on the disc side, so I'll play with the ground balance until I can get a signal on the disc side and then note where the ground balance is set. Sometimes it doesn't work because the signal is just too deep and only all metal can reach it.
The map is important, it lets you know which items are what, and roughly where. You might consider taking it a step further and bury some trash items at different depths as well at varied closeness to the good targets. It'll give you a little insight as to how signals sound when a combination of good and bad targets get under and around the coil at the same time. To determine good from bad, sink golf tees directly over all the items. I use white tees for the coins and rings, red tees for the trash. It's very revealing when you know exactly what your over, especially those targets you placed trash in close proximity. Experimenting with swing speed and direction in these spots is a great way to learn what your MD is telling you.

Ric,
Excellent thoughts. Last weekend I did a little air testing with one of my PI detectors and re-enforced that sweep speed makes an important difference. Also, that speeds one detector does better at are not speeds a different detector does well with.

Steve,
I think that you are wondering about Monte's "power balancing" and yup it works on my old ED-120 circuit Tesoros like the Toltec ll and the older Bandido's, Pantera etc. I have an older coin test garden that I planted about 12 years ago, even though my ground is mineralized a little bit, the ground balance setting with just a touch positive does not do well in my ground. I find that a setting of a neutral ground balance setting or just a little less (threshold goes null or almost silent) will make the detector more responsive in the motion Disc. mode to higher conductive coins such as silver dime,quarter and even half dollar. This ground balance setting also lets me use an audible threshold to have a workable theshold for the all-metal mode. Hope this helps. Maybe later I will make a new thread about building a good test garden that will work as soon as you have planted the coins and .......yet......... my test garden has deep coins/targets in the ground.

Thanks Randy, and it would be great if you would make a thread about building a good test garden when you get time. Steve.Hombre said:Steve,

A test garden is a great idea and I have one, not really organized though. Another really good way to learn your detector is make a video as you over the target , explain the sound you hear also record the sound,then dig the target see and tell the depth and make a note of what it is. If you do this a bunch then watch them back you will get a real world training from yourself.
Its really a great way to help you learn, like football players watching tape of the game.
Though this method is not really quick. But If you make a test garden really you may have to wait a few years for the stuff to get mineral halos to get a real depth idea.
