13 mm ID tags

The Thelma Biotel 13 mm Acoustic transmitter is available in multiple power versions. These transmitters are intended for use where high output power and long transmitting life is crucial. The transmitters are suited for both manual tracking and automatic monitoring of larger fish or other aquatic animals.

The 13 mm Acoustic Transmitters are delivered both as Continuous Pingers and ID Transmitters. The customer specifies pulse delay or coded ID and type of encoding scheme, transmitting frequency and minimum and maximum random delay for ID transmitters.
