New update Southren California Field Test of the Minelab/Garrett/White's
Here is a new update to my field test. I got a Sun Ray Stealth X-5 for my Explorer XS and here is the result, ten cent piece at 6" deep, and the 25 grains gold coin at 5" deep, and the 7 grains gold coin at 4" deep. With this coil I could run the power all the way up to 32 with very little false signals but for the test I ran the power at 25 so there were no false signals, Iron mask set to 0" and the discrimination is blackout from the far left to the mid way as far as the zero iron mask go to, and from top to bottom.
Field test, of the Minelab detectors. Explorer XS and a SD2100 and the Garrett detectors, GTI 1500 and GTA 1000, and the Whites detector, Goldmaster II. This test will be done in southern CA. at Daggett CA. I will dig a hole that is about 5" OD. and as deep as the detector can detect the target. As doing a normal search method, the coil being swept about 1" to 2" above the ground and getting a fair to a good target signal. After placing the target in the hole I will bury it to more simulate natural conditions. With larger coins the detectors will go deeper. But this is a test, of some of the smaller target. The target will be a 1905 USA silver ten cent piece, 17.9mm, OD. and 2.50 grams in weight, and a home made gold coin at least 90% pure gold, that represent a USA 1 dollar gold coin, 13mm OD. and 25 grains in weight. and a 24kt. gold coin, 10mm OD. and 7 grains in weight, and a piece of gold 0.9 grain in weight. See photo of the hole and test coins.
Testing the Minelab Explorer XS. I pressed and held the power button until the factory presets setting is return. Then I set the Audio volume, (Max limit at 10) (gain at 10) Tone, (Th tone at 5) (Variability at10) (Limits at10) Sounds set to (Conduct) Options (Noise set to 5) (Response to audio 1) (Recover set to Fast and Deep) Sensitivity set to manual, and the power set to 25 were there is, very little false signals Iron mask set to 0" and the discrimination is blackout from the far left to the mid way as far as the zero iron mask go to, and from top to bottom.
Testing the 18" Excelerator E coil for the Explorer XS, Target result are, ten cent piece at 7" deep, and the 25 grains gold coin at 6" deep. and the 7 grains gold coin at 5" deep.
Testing the 14" Excelerator II coil for the Explorer XS, Target result are, ten cent piece at 9" deep, and the 25 grains gold coin at 8" deep. and the 7 grains gold coin at 7" deep.
Testing the 10.5" Factory DD coil for the Explorer XS, Target result are, ten cent piece at 9" deep, and the 25 grains gold coin at 8" deep. and the 7 grains gold coin at 7" deep.
Testing the 8" Explorer FBS coil for the Explorer XS, Target result are, ten cent piece at 7" deep, and the 25 grains gold coin at 6" deep. and the 7 grains gold coin at 5" deep.
Testing the 5" Excelerator E coil for the Explorer XS, I had to lower the sensitivity to power # 7 to stop all of the false signals. Target result are, ten cent piece at 4" deep, and the 25 grains gold coin at 3.5" deep. and the 7 grains gold coin at 3.5" deep. Then I blackout or added discrimination on the # 16,17,18,19, little squares on the the far right and up from the bottom on the LCD. Then I could increase the sensitivity up to power # 15, with out having false signals. Target result are, ten cent piece at 4.5" deep, and the 25 grains gold coin at 4.5" deep. and the 7 grains gold coin at 4.5" deep. The discrimination is blackout from the far left to the mid way as far as the zero iron mask go to, and from top to bottom, and that little bit on the far right, squares # 16,17,18,19 up from the bottom.
Testing the Minelab SD-2100, the detector was set to factory setting, and I used a Gold Rush Depth Master audio amplifier to increase the target signal.
