Specifications SheetG6 DST
Overview
The Cefas G6 is based upon the tried and tested Cefas G5, logging pressure and temperature, but it offers the additional benefits of a longer life and much larger memory capacity. The tag is capable of taking up to 40 million readings from its pressure or temperature sensors over the life of the battery.
DST users want greater programming flexibility, so key features of the G6 are its independent pressure and temperature settings. Repeat Logging allows users to configure short bursts of data logging over an extended period of time.
If your research involves studying diving birds and mammals, you will be interested in our Dive Switch and Fast Logging Rate. The dive switch allows the Fast Logging Rate to be activated when the animal enters the water so that dive profiles can be measured.
- Fast Logging at rates at up to 10Hz
- Fast Logging Rate activated by entry into water
- deactivated by removal from water / return to surface
- operates in fresh water and seawater
Robustness and reliability of the Cefas tag technology comes as standard.

Notes
- Optional depth sensing ranges available
- Under normal operating conditions and single memory fill. Multiple deployments may significantly affect the tag life
- Accuracy degrades outside this range.
- Typical time to reach 66% / 90% of step from 5 to 30 degrees
