How To Get Maximum Depth + Performance Out Of Your AT Series ( Pro & Gold)
* With the AT Pro, learn and hunt in Pro mode. It is deeper then standard mode. With the AT Gold, the all metal mode is deeper then Disc 1 or Disc 2.
* Has a place been hunted out? Go back and try again after a good rain soaking. Moist wet soil gives better sensitivity and greater depth readings for targets.
* If you get a nice high audio and a VDI in the 70's or 80's, dig it.
* The larger the coil the deeper it goes. However, too many targets under a large coil can mask a good target. If you get a slight good audio using the large coil, lift it up 2-3 inches and center the coil where the good audio was. Often times the good target will be much clearer.
* Get a coil cover and scrub the ground. Some people scan the ground inches above it...."DON'T" You can gain a couple of inches scrubbing, which is significant.
* Don't swing too fast! Just because it has a very fast "recovery speed"......doesn't mean it can always pick out that one good silver coin amongst several pieces of junk. The electronics still need to process lots of information.
* Swinging too fast can make you a sloppy hunter. You also risk eventually cracking/breaking your coil and elephant ears from the constant banging on trees, playground equipment or concrete.
* If you are getting lots of EMI or increased mineralization which is causing erratic audio, try adjusting your discrimination first, before lowering the sensitivity. This sometimes lets the machine run smoother without losing any depth.
* If you get mixture of audio signals, scan the target from different directions. Sometimes a good target is beside or partially underneath a good target. The AT Series has a unique ability to pick out those good targets amongst the trash. Going at the target from different directions allows the AT Pro to perform even better!
* Ground balance your machine occasionally. Temperature can change, and directly affect the settings. Hunting in shade vs. sun can vary. "a 14 degree difference on a lawn area to a 35 degree difference on a parking lot." But, the mineralization can also change between areas....so again...ground balance periodically.
* To increase the depth/sensitivity to silver targets, lower the ground balanced numbers 10-20 points
* If you are hunting an area that is absolutely covered with nails, try ground balancing out a nail until it is nothing but a small amount of static. Now....all the copper & silver targets will give a loud audio response....BUT the target ID will be off.
* Build a test garden...use good & bad targets at different depths. You will soon discover that deep silver targets beyond depths of 8 or more inches begin to not sound off as a high pitch or that the VDI numbers remain in the 80's. That is very good information to know. My rule of thumb states if it's deep....it's old. Dig it! It costs you nothing.
