(Sized for wells)

This unit gets its memorable name because it's narrow enough for measuring water in wells that are quarter-inch in diameter or even partially blocked.  Its high strength polyethylene tape is a skinny 0.24 inch and is marked to engineering scale: feet and tenths with markings every 1/100ft (millimeter version not available).  It signals water with a bright LED light and solid buzzer tone contacting water.  Includes: slim 1/4" (6.23) probe.

Features:

-Narrow 1/4" tape and non-submersible probe
