The Axy-Trek Marine is a small data logger with GPS internal antenna, a tri-axial accelerometer and a pressure sensor (TDR), designed for marine animals. The Axy-Trek can record a large amount of different behavioural data at once, allowing a new range of behavioural studies. Fully schedulable device to meet a wide range of research needs. Several sensors can be included in this device such as pressure/temperature, light and dry/wet.

Specifications
The Axy-Trek Marine is a small data logger with GPS internal antenna, a tri-axial accelerometer, and a pressure sensor (TDR). The pressure sensor records up to 300 meters in depth. The combination of GPS and accelerometer allows researchers to collect a large amount of different behavioural data at once, allowing a new range of behavioural studies. The high-resolution accelerometer measures the acceleration of the body along with three directions and that allows the researcher to characterize different behavioural patterns and estimate the energy expenditure.
Light sensors and water-switch can be included in this device. Such add-in sensor can be used in specific situations where is needed to switch on/off the GPS to significantly extend the recording time of Axy-Trek. Despite the Axy-Trek Marine was designed for marine species, it can be used also in terrestrial animals where an internal antenna is needed.
Axy-Trek Marine has been used in several species of reptiles, birds, and mammals.
Axy-Trek is highly customizable to meet all possible research needs, and be used in a wide range of species. Available with a high-efficiency solar panel.
