Pin-Pointing the Sonde
Note: The receiver handle must be oriente d perpendicular to the sonde. The
cross bar of the receiver must be in line with the sonde ( the opposite of line
locating).
1.. .Set.the.receiver.to.Sonde.mode.by.pressing.the.Sonde.key.until.the.
frequency.of.the.sonde.appears.on.the.locate.screen.
2.. .Holding.the.receiver.perpendicular.to.the.suspected.path,.walk.the.path.u ntil.
the.receiver.detects.the.first.peak.signal.of.the.sonde.
3.. Adjust.the.gain.down.if.the.bar.graph.closes.completely.
4.. .Continue.to.walk.the.path..Observe.the.response.of.the.receiver.as.the.center.
(and.strongest).peak.of.the.sonde’s.magnetic.field.is.detected.
5.. .Continue.past.this.strong.peak..The.signal.will.fall.and.then.r ise.again.as.the.
last.weak.peak.is.detected.
6.. Retrace.your.steps,.watching.the.receiver.
7.. .The.sonde.has.been.pinpointed.when.the.center.of.the.strongest.peak.has.
been.found.
8.. .Measure.the.depth.of.the.sonde.by.placing.the.tip.of.the.receiver.on.the.
ground.and.pressing.the.depth.key..Refer.to.receiver.set.up.section.to.select.
