Mounts easily on the drill rod, measures depth on 4–10 mm wireline, and syncs live over Bluetooth® for traceable, QA-ready surveys.
Measure wireline movement precisely on open or cased holes with support for 4–10 mm (0.15–0.39″) cables. Maintain consistent depth control across changing field conditions and improve confidence in every run with reliable, repeatable readings.
Compact and lightweight, the unit mounts directly on the drill rod—or on a tripod/clamp—so crews can deploy fast and track depth accurately without slowing operations. Simple setup delivers dependable results shift after shift.
Long-range Bluetooth® (up to ~20 m) streams depth data to SPT handhelds and apps in real time. Keep logs synchronized, enhance operator safety by standing clear of moving parts, and reduce manual errors with wireless, live monitoring.
