Depth Counter

Ensure survey accuracy with precision depth control. Lightweight, compact and easy to use measuring device.

Compact and lightweight device for measuring wireline depth

The SPT Optical Depth Counter device is designed to be mounted to the rod of a drilling unit. One of the benefits compared to other measuring devices is that it measures depth on wireline cables from 4mm to 10mm (0.15” to 0.39”). This device can work on both open and cased hole, using a tripod or clamping device.
