PRL-1 can penetrate various surfaces like wood, paper, and soil.
Cannot penetrate metal to locate other metal items.
Sweeping loop close to surface and in motion is critical.
DISC control selects trash rejection; clockwise increases rejection.
Adjust DISC for reasons like detecting iron/steel or most valuables.
Center position used for most searching, allowing trash rejection.
Squeeze/hold or LOCK toggle for pinpointing or iron/steel detection.
1/4 inch stereo jack located below elbow cup, above battery compartment.
Most 1/4 inch headphones (8-120 ohms) work; select with volume controls if needed.
Headphones increase battery life, operator hearing, and privacy.
