A 100-foot water level indicator is a portable, spool-based tool used to precisely measure the depth of groundwater in deep wells, boreholes, and standpipes. It features a high-strength cable marked at precise intervals (e.g., every 1/100th of a foot) and an electronic probe that triggers a buzzer or LED upon contacting water.
