Lotek KiwiSat® K4G 154E and K4G 154F are lightweight marine Argos transmitters for glue on attachment. Each model is carefully designed with a compact shape, minimal frontal area and can operate down to depths of 500m and 200m respectively. These tags maximize the benefits offered by the Argos-3 network meaning that transmit power can be halved for the same amount of data throughput and error rates, thereby minimizing the transmitter size.
Ideal for Penguins and other marine animals.
