bestresultsareobtainedwhenthereceiverisinafullyextendedposition.Depthmeasurements

andthesignalstrengthisadequate.SpecialconsiderationsarerequiredfortheSondemode(see
SECTIONVIII:OPERATINGRECOMMENDATIONSfordetails).
AutomaticandManualOutputPower
ThetransmittersoftheXTpclineofpipeandcablelocatorsdeliverpowertothe"load"connectedto
them.Intheconductivemode,theloadisthecircuitformedbythecableorpipebeingtraced,the
soilreturn,andthegroundstake.Intheinductiveclampandinductivemodes,theloadsarethe
clampandtheantenna,respectively.Theinductiveclampandinductivemodesrequirethemaximum
powerthatthetransmittercandeliver.Therefore,thetransmitterautomaticallyoperatesat
maximumpoweroutput,andthereisnoneedformanualpoweradjustment.
Intheconductivemode,thepowerdeliveredtotheloadishighlydependentontheexternal
elements(soil,typeofconductor,stakeplacements,etc.).Insomecases,morepowerisdesiredto
achievemoredistanceordepth;inothercases,lesspowerisdesiredtoavoidbleedingtonearby
conductors.Therefore,whileintheconductivemode,theuserhastheabilitytoadjusttheoutput
