Performance
The Mapping Display confirms a good locate signal and identifies distortion in congested areas using:
• Target Line – Guides the operator down the line and shows changes in direction.
• Left-Right Guidance Arrows – Points the operator to the target utility.
• Proximity Signal and Signal Strength – Helps the operator center the locator closer to the target
for more confident locates.
Other features include:
• Continual Depth – Increases productivity by showing depth changes in real time.
• Omni-Seek
®
– Increases accuracy and efficiency when searching in passive mode. Continuously
searches passive power and radio bands to locate and avoid unknown metallic lines.
• User-Defined Frequencies – RIDGID SeekTech SR-20 Receivers can be configured with up to 30 user
defined frequencies between 10 Hz and 35,000 Hz.

SR-20:
For users wanting a lightweight yet rugged
receiver that provides all the information needed for
faster, more accurate locates:
• Target line and guidance arrows quickly
identify distortion.
• Proximity signal and signal strength help
work through difficult locates.
Choose the SR-20 and learn to locate with more
confidence.
SR-60:
For users wanting the fastest, easiest, most versatile receiver available:
• Can trace any frequency from 10 Hz to
490,000 Hz.
• Can trace energized lines and sondes (active beacons)
simultaneously.
• Has all the ease of use and accuracy of the SR-20
but with ALL locatable frequencies.
Choose the SR-60 for fast confident locates even under
tough locate conditions (poor conductors, poor soil condi-
tions, poor grounding, etc.)
