First off, the program: All metal, threshold level 16, volume limit 30, volume gain 24, response- long, Tone ID: multi, conductive sounds, variability 30, limits 30, Expert: deep-on, fast-off(although some targets did better at a faster sweep speed) trash density-low, ground-neutral, noise cancel 9 (extremely stable @ max sensitivity inside my house) also, was using the pro coil. For this I manually maxed the sensitivity and "air tested" various U.S. coins, a thin 10K gold ring, and a thin 1in X 1in marijuana leaf charm. depth of items is calculated in inches @ the point where the signal would just begin to get choppy but was still solid. All coins were passed across middle of coil facing the coil and not sideways for this experiment. The results are as follows: 1978 big dollar-17 ½ in Franklin and silver half dollar-16 in silver quarter, clad quarter and clad nickel-15 in IH wheat-14 ½ in, silver merc and clad dime -13 in. After this I manually lowered sensitivity to 16. The results are as follows: 1978 big dollar- 10 ½ in Franklin and silver half dollar- 10 in clad nickel-9 in clad and silver quarter-8 ½ in IH and wheat cent- 8 ½ in clad and mercury dime 8 in Thin 10K gold ring- 12 ½ in (solid) Thin 14K gold leaf pendant 1 in X 1 in- 9 ½ in ( lil choppy) This next experiment was conducted with a silver mercury dime as I passed it across middle of coil facing the coil, not sideways and at what point the signal became choppy but still audibly detectable as I lowered manual sensitivity beginning at 30. Calculated in inches: mercury dime at… 30 MAX – 13 in 29-12 ¼ in 28-12 ½ in ( ¼ in more from 29 to 28) ( the results found from sensitivity 28 to 23 are rather interesting) as follows: 27- 12 in 26-12 in 25-12 in 24- 12 in 23- 11 ½ in 22- 11 in 21- 11 in 20- 10 ½ in, 19-10 in , 18-9 ½ in , 17- 8 ½ in , 16-8 ¼ in , 15-8 in, 14- 7 ½ in, 13- 6 ¾ in , 12- 6 ½ in , 11- 6 in, 10- 5 ¾ in, 9-5 ½ in, 8-5 ½ in, 7-5 in, 6- 4 ¾ in, 5- 4 ¼ in, 4- 3 ¾ in , 3-3 ½ in, 2- 3 in, 1- 2 ¾ in
