Prizm™ III Controls
In.addition.to.the.features.of.the.Prizm™.II,.the. Prizm™ III.
has.an.additional.feature.-
1...The.depth.of.coin-sized.metals.is.automatically.indicated.on.
the.lower.left-hand.portion.of.the.display...
2...Metals.larger.or.smaller.than.typical.coin.size.will.skew.
this.indication.slightly...For.example,.a.pop.can.will.indicate.
very.shallow,.however,.may.in.fact.be.found.quite.deep.in.the.
ground...A.metal.much.smaller.than.a.coin.will.indicate.quite.
deep,.however,.be.found.to.be.quite.shallow.in.the.ground...
Whatever.the.finding.regarding.a.particular.size,.the.results.
will.be.consistent,.repeated.time.and.time.again...If.a.metal.........
indicates.an.inch.and.after.digging.three.inches.it.is.still.not.
located,.that.item.is.larger.than.a.typical.coin...If.pop.cans.are.
common.to.the.area.disregard.
3...Typically.lighter.metals.like.the.aluminum.pull.tab.will.
remain.fairly.shallow...A.TAB.indication.that.indicates.fairly.
shallow.is.likely.a.TAB...However,.gold.is.heavy.(typically.sinks.
more.deeply.into.the.ground).and.may.also.indicate.in.the.
TAB.area.of.the.display...A.TAB.indication.that.indicates.fairly.
deep.should.be.dug,.at.least.until.determined.that.deep.tabs.
are.also.common.to.the.area...Older.more.collectable.coins.
are.found.at.greater.depths.in.the.ground...Deep.indications.
that.have.questionable.tone.and.display.indications.are.more.
worthy.of.investigation.compared.to.questionable.tone.and.
display.indications.that.produce.shallow.depth.indications.
4...Regardless.of.the.metal.detector.used,.when.searching,.you.
are.going.to.dig.some.trash.metals...Use.the.tone,.display,.and.
