Went out with the 705 with stock 9 in. and also tried the 6 in. Found one ring about 3 in. deep that come in at 8. Also just clad around $1.45. The soil balanced around 16-18 and was very dry. Was running sensitivity around 24-26 and run smooth. Used four tones. I did not dig any targets over 4 in. deep. The depth icons seemed to read deeper than the targets were with both coils. Being very dry is this common? Found I have to slow down I think as I'm use to hunting alittle faster with other units. In checking targets I switched to all metal and if I heard any iron I moved on is this the normal thing to do? Thanks for any help. Joe
