Specifications SheetG6A DST
Overview
The Cefas G6A is a new product that includes a 3 axis accelerometer ±2g in addition to the usual pressure and temperature sensors. This tag also has a larger battery to support the logging of data at up to 30Hz, which offers a combination of longer life and larger memory capacity. The tag is capable of taking up to 40 million readings from its sensors over the life of the battery.
DST users want greater programming flexibility, so a key feature of the G6A is its independent sensor 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 up to 30Hz
- 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
- Accuracy degrades outside this range.
- Typical time to reach 66% / 90% of step from 5 to 30 degrees
- Accelerometer channel can only be logged at 8 bit resolution. Giving ~129 hours at 30 Hz with all 3 channels.
