The FM 9800 series serves for an easy location of the exact track and depth of cables and metallic pipes. With two passive and up to three active frequencies, the FM 9800 is an universal line locator. The waterproof 3 watt transmitter automatically selects the optimum search frequency. The simultaneous output of a all active frequencies let you verify your measured result immediately. A built-in ohmmeter automatically measures the line resistance. 

• Two active frequencies (9.8 kHz & 82 kHz)
• D Cell Transmitter Batteries
• Patented "distance sensitive left/right guidance"
• Automatic "real-time gain" adjustment.
• Current measurement for distinction between parallel lines and for location of tees.
• Digital push button depth measurement in cms.
• Passive 50/60 Hz and radio frequency location.
• Automatic "best" frequency selection.
• Built-in Ohmmeter provides information on line resistance and quality of ground connection.
• Continuous automatic impedance matching of the transmitter. Intelligent transmitter and receiver with acoustic and optical indications.
