Hey all in CZ land.I have been working under the bleachers at a near buy high school for a few months.I use my cz70 with the 5in coil,sens on 2(bleachers are metal),and accept all targets but iron.I dig every round/square tab,5cent,zinc,high coin signal.I dig foil signals untill I cah't take it anymore,then just dig the stronger/bounce foil signals. I got a "perfect" round tab signal,that turned out to be an 18k catholic medallion.I was trying to keep a tabs to gold log going,but stopped counting tabs at 700.I love this spot,but walking hunched over and constant digging kill my lower back.I have been detecting since 1991,and this week I hit my first trifecta:"jar of coins"-silver coin-18k medallion! I am a happy camper. HH.
