* While, future predation detection may be included in all 900-Series Tags, they are presently only offered in the 900-PB and 900-PD.
Estimated life can be extended by decreasing Pulse Width (PW) and/or increasing Pulse Rate Interval (PRI). Tags operate at 307 kHz or 80 kHz. Length, diameter, & weight may vary +/- 10%. Life quoted is based on operating parameters of 1 msec pulse width, single pulse, at 10°C. Acoustic / PIT Tag combinations are available for all HTI Acoustic Tags.
