Geotech ETL Water Level Meter — Manual Rewind Reel

Deep-well water level measurement from 1500 to 3000 ft (450–925 m), on a crank-assisted manual rewind reel. Past about 1000 ft, retrieving a wet tape hand-over-hand becomes slow and hard on the tape — a geared rewind handle does the work, keeps the wind even, and gets the tape back on the reel without kinks. Same measurement performance as our standard reels: accurate to roughly 1/100 of a foot per 100 feet, with a field-serviceable 5/8" (1.59 cm) probe on polyethylene-coated steel tape, marked in engineering scale or metric. PFAS-free construction. Choose your configuration Tape material — Poly or MDPE, both polyethylene-coated steel. MDPE runs slightly less per length. ETFE available on request. Length and markings — 1500–3000 ft marked in feet, or 450–925 m marked in metres. Tape is marked in one system only, so order the units your logs use. These reels are supplied with the 5/8" probe only — the 3/8" probe is not offered at these depths. There is no carrying bag option for this reel size. Which rewind do I need? Manual rewind (this reel) — geared hand crank. Lower cost, nothing to charge, nothing to fail electrically. Good for occasional deep readings. Electric rewind — powered retrieval, and the only option past 3000 ft (to 5000 ft). Worth it if you're running deep wells all day or your crew is doing many wells per shift. ET / ETL standard reel — 100–1000 ft / 30–300 m, and where the 3/8" probe option lives.
