Tried a bit of air testing on the 1236-X2. I don't consider these tests definitive, as there are too many variables out in the field. But they are indicative of general performance.
The settings for the test were as follows
SENS - 8.75
This is just under the electrical noise from the shop flourescents. ANy higher and I had audible interference. Interestingly, I cannot run any higher than this out in town.
VOL - 9
I use adjustable volume headphones, or keep it as loud as is confortable.
FREQ - "0"
Adjusting this control makes no difference in the presence of the shop electrical noise and I got no more SENS by shifting frequency.
DISC - IRON preset and "4"
"4" is the notch below nickel. The results were the same for both settings, with no appreciable change in "depth" attained.
NOTES:
1. All target responses were considered good when a solid, repeatable, audio was attained. The 1236 exhibits amplitude modulation on it's target response, so responses are weaker the farther the target is from the coil. That is, the deeper the target, the weaker the emitted audio response.
2. As the targets get closer to the coil, the response gets louder. In each case, the audio volume rose dramatically within the first inch or so of the target moving toward the coil from its farthest audible response point.
3. NOTE: It was again seen that the 1236-X2 hits harder on distant targets, when they move quickly within the detectors field. This seems to indicate that faster sweep speeds give an increase in detectable depth.
Common range targets
Nickel ... 8"
Wedding band ... 8"-9"
Square tab ... 7"-8"
Ring pulltab ... 8"-9"
Zinc Memorial cent ... 8"-9"
Copper Wheat cent ... 7"-8"
Clad dime ... 7"-8"
Clad quarter ... 8"
Silver Half ... 9.5"
Common non-coin targets
Hot wheel car ... 11+"
Car key ... 9"
Dog Tag ... 9"-10"
Shotshell base ... 9"
Miltary coat button ... 9"-10"
It is apparent that the 1236-X2, with stock 8" coil, has sufficient sensitivity for the majority of hunting uses. With these numbers and the "hotness" of the detector in general, I think a large coil for the deepest of relics or coins could be useful.
I expected a stronger response from the quarter and was a little surprised to not get it. I was also surprised that the zincer gave a better "hit" than the Wheatie.
But, such tests are arbitrary as most of us know, and cannot be taken as definitive.
