Umax with negative GB.
- Thread starter twotap
- Start date
I can run my Vaquero with about 1/8 turn negative ground balance with absolutely no problems with the disc circuit. I seem to get about two more inches of depth and the disc is "spot on". I have had many Tesoros and until I watched a Youtube video showing the depth increases with negative ground balances, I was in the dark. Too much will cause an erratic disc problem. I believe it was Tabman's video that I watched.
In my mild Kansas soil, haven't seen any improvements in depth running a neg. ground balance. In fact, I like to use the threshold all-metal and it is useless running a neg. GB. With my Outlaw, when adjusted to a 'spot on' per the manual GB.......I get plenty of depth to reach the deeper older coins and relics. Plus, I can size and shape the found target in all-metal to see if it... and the modulated audio of the Disc. mode signal are close in sound. If they match, it is usually and old coin or small relic like a coat button or token The threshold all-metal, when used and understood is a great aid to finding the targets you are looking for.
Randy, I wish the Vaquero had a switch for all metal-disc. The Outlaw has a switch and I find it to be a pain to turn the knob into all metal. Sure it can be done, but a quick tap on the switch makes checking targets from disc to all metal and vice versa. For the record, I only run a negative ground balance in places with little iron. It seems to enhance rusty iron. I just brought my two detectors to my new house which is not that old. I found forty clad coins in less than 45 minutes and I had a very rare clad find. Two dollar coins in the same hole! A couple of feet away comes 4 quarters. There were 5 kids in this house at one time.
RL....There are several reasons I like the Outlaw, # one is that it has the old style ED-120 Disc. circuit that Jack designed, # two is the static All-Metal mode that was dropped when they discontinued the Bandido ll µMax. All the other Tesoro models have an AUTO TUNED all-metal circuit, that is..it requires some motion so that the circuitry keeps the signal. The Outlaw brought back the 'no motion' all metal as some people are fond of calling it, it is a 'static' all metal mode and will hold the signal as long as you hover the coil over the target. It is a great aid in determining the size and shape and perception of depth of a found target that the AUTO TUNED all metal is not capable of.
