Depth calibrator

Depth calibration has just been simplified. MGB-Tech developed a
tool that is both accurate and easy to use.
Our calibrator consists of two modules: a portable command unit
and a remote transducer.
The remote transducer is built into a reel. It incorporates a battery
pack, 24-bit measurement circuit and radio unit. The user interface
incorporates a rugged battery pack, large LCD and is delivered in a
shock resist carrier bag which enables excellent portability.
