For parks:
start in Relic mode.
discriminate out (ie, black out)everything except:
...39 for silver
...38 for quarters
...37 for dimes
...36, for copper pennies (this is where wheats come in for me too)
...32-35 for zinc pennies and various brass thingies (I hate zincs and usually all these #s out too)
...13, 14, 15 for nickels (this is also pulltab country and you may want to black out some or all of these, depending on that days tolerance for pulltab digging)
For relics in the woods, just push the Relic button on the upper right and have at it.
That's It. While you are learning, concentrate on the TONES ONLY that these numbers give you. Get to where you can tell what is under your coil by sound only. Only use your screen for an approximate depth estimate. Yes, this will leave LOTS of goodies behind for various reasons, but this is an easy way to learn your machine. You can go back to the same park later and get the tougher stuff after you get better. If you try to hunt now before you learn the basics with most of the range open, you will drive yourself crazy and maybe sell your machine at a huge loss while cursing it loudly.
Understand that the numbers may vary slightly from day to day (soil moisture?) and even from machine to machine. But the song remains the same. (yeah, LZ fan here) Don't trust the #'s on the screen- youre going to but if you stay with it, youll understand someday why you shouldnt.
If you don't understand what Ive posted or any of the above posts, you need to reread your manual before hunting. Until you understand these basics, you will be wasting your time and getting greatly frustrated. The Safari is a fantastic machine, but it takes some initial effort to learn to use it well. I had years of metal detecting older/lesser machines and it took me 10's of hours before I felt comfortable with my Safari. Now its my Goto machine.
