Another thing I am noticing with the LTD in the bp mode is it locks on slightly deeper nickels a little better then the regular F 75 does. 2 of the 5 nickels I dug today were 5 and 6" and read a solid 30 with a good clean high tone in 3h tones. Nickels deeper then about 4-5" with my regular F 75 were always a little bouncy vdi wise. HH jim tn
