The RD8100PXLM is Radiodection's entry level underground locator to the renowned RD8100 RF marker locator range. Containing a built in transponder, the RD8100PXLM is designed to meet the needs of users requiring a high level underground locator with advanced features for precision underground service locating. With 17 active frequencies, ranging from a low frequency 512Hz up to a ultra high 200kHz frequency, the RD8100PXL gives the operator additional fexibility of locating a range of buried utilities and infrastructure. The transponder, built into the RD8100PXLM can detect buried utility RF markers, making them suitable for use across a range of industries. Combined mode allows for scanning of buried cables, pipes and RF utility markers all at the same time, reducing survey time and offering a more simplistic user experience. Radiodetection's unique automatic depth estimation provides measurements when the locator is within close proximity of a RF marker. Rechargeable Li-Ion batteries are standard across all of the RD8100 marker locators, and all are equipped with Bluetooth and iLOC connectivity for remote control of key transmitter functions.
