I will be interested in hearing the reply to this question. I used this program the last time I went to the beach with some tweaks. Salt sense 6. Reactivity 0. Changed from square tone to pwm. Sensitivity 96. Found that a slow sweep speed actually hurt my depth and tid. I was probably sweeping back and forth in about 2 seconds. Got much better depth with a sweep speed of about 1 second. I found a South African cent at about 12 inches. This coin is tiny! Probably smaller than a trime. Also, found a dime high up on the beach at 16-18 inches, much to my shock. This was high enough on the beach that the hole was dry, so no false depth due to water infiltration. Loving this detector! This program is not in the manual because it was part of the .71 update. Surprisingly, I did not see anything about it on the XP website….
