Had some time Thursday afternoon so I ran out to a park that I've found old stuff at in the past. Detected slowly, listened for deeper targets. Ended up with 15 wheaties, 2 Indians (1902 and ????), a '35 Merc, a 1914 Barber and a sterling "I'm a Catholic" medallion. Most of the coins were 7-8 inches deep. I have been hunting in combined mode then switch over to "e-Trac" mode to double check the good targets, gives me a different perspective. I also find that this solves the problem that I've noticed of old, rusty bottle caps hitting like deep nickels- as soon as you switch over to conductive (high trash) their true identity is revealed.
