LC2000-2

The LC2000 design, which all our instruments are based around is relatively compact and lightweight which, in turn makes them easy to handle on deck and ship by air if necessary to support a project at short notice. Their simple design, construction and light weight makes them easy to deploy from the smallest of sea-going vessels.

Turnaround time between deployments is minimal as data can be downloaded and the loggers reprogrammed without opening the pressure vessel; the recorded data can be translated to SEG-Y and provided to the clients within 30 minutes of recovery if shot times are available.
