Thanks for the replies .....I guess it's a matter of preference as to whether to run in Conductivity mode or in Ferrous mode depending on what tones you hear better ......I had an interesting time out on Saturday ...I had thought that as long as I did a noise cancel , that my Auto Sensitivity was in full effect ....Then I started messing with my Sensitivity and did my noise cancel and realized that the Sensitivity stayed right where I put it ....Hmmmmmmm....I thought I was in Auto Sensitivity, but my number stayed right where I left it ....Hmmm . strange .... ....My buddy looked at me and said " So how do you go into Auto Sensitivity " ....I looked at him and said " all I have to do is noise cancel " ....Well , when I saw that it wasn't working I was lost ....I didn't know what to say, and I was searching all over the Sensitivity range for a way to work with the Safari, all the while trying to find where "AUTO SENSITIVIY " was ...... ...I finally jacked the Sensitivity all the way up till it couldn't go any further in frustration , and lo and behold , the Auto Sensitivity showed itself for the FIRST TIME !!!.....Now I was FINALLY in Auto Sens mode !!!.....I've read every book that Andy put out and there is NO MENTION at all about how to go into Auto Sensitivity mode !!.....It only says that the Safari is shipped in Auto Sens mode ....Well i bought a used Safari .....I felt relieved and STUPID at the same time when I finally found Auto Sens !!..... I can tell you this much , there was a lot less going on in my headphones in Auto Sens mode .... So the Sensitivity was running too high most of the day !!!.... Perhaps a notation about how to get into Auto Sensitiviy would be in order ..... I would hope to think that I'm not that stupid ....??????
One other thing that through me off was the number 40 popping up right at the edge of the null .....Every time I heard that , I was thinking SILVER !!!!..... I would go back to it and would most of the time never get it to repeat moving the coil at different angles ......Again, my sensitivity being too high didn't help either .... It was when I FINALLY got everything working correctly , that I came across my first Silver Dime !!!........An 1898 Barber !!!.....YES !!!!.......I was a happy camper !!!.... I think that with my hearing that I will stick with the Conductivity Mode for my coin hunting ....That higher pitch and the higher numbers just hits me better than the lower pitch ....I stayed in Low Density as the book said you can go deeper with the Low Density setting .....I will also try High Density to see how I like it ..... I can see an E trac in my future , unless a new Minelab comes out that betters it .....I'm glad I started with the Safari ....It's a pretty easy machine to run, and set up properly, it will hit some great targets .... No , it's not pefect , but I don't guess ANY machine is .....It works for me , for now, and that's all that counts ....Jim
