The 101 Water Level Meter is very sturdy and gives easy-to read, consistently accurate water level measurements in wells and boreholes.

The tape is permanently marked each 1/100 ft or each millimeter, in lengths up to 6,000 ft (1,800 m). The tape has stranded stainless steel conductors for long life and easy repair. A dog-bone tape design reduces adherence to wet casing. Probes have recessed sensors to minimize false signals. The optional P6 Submersible Probe is leak-proof, which allows submergence to 1000 ft (300 m).

The well balanced reel has a carrying handle, an easy-access battery drawer, and an excellent brake. A 9V battery powers the buzzer and light, which activate when static water is reached.
