MAP-Series acoustic transmitters are designed for operation with Lotek’s unique MAP digital encoded telemetry systems. MAP acoustic systems permit the unique identification of over 80,000 individual animals. Both ID-only and ID plus sensors (temperature, pressure/depth and/or motion) can be simultaneously monitored and recorded. Unique CDMA digital coding permits simultaneous detection of hundreds of co-located transmitters at high repetition rates (to 40 transmissions per minute per tag), yielding data with higher temporal resolution and higher detection rates when compared to analog coding systems. When used in conjunction with WHS 3250 submersible receivers and Lotek UMAP positioning software, continuous high resolution 2D and 3D tracks of tag location in time are calculated.
Suitable for all types of acoustic tracking, the Miniature MAP Series acoustic transmitters are particularly well suited for large scale fish tracking and positioning studies, due to their high noise immunity and collision resistance.
These tiny acoustic tags are ideal for studies where short burst interval and fine spatial resolution is required, and/or where hundreds of fish may congregate in the study area.

1. Stated specifications may vary by +/- 5%
2. Calculated life may vary, based in part upon environmental conditions to which the tags will be subjected.
All transmitters are guaranteed to meet stated specifications upon shipment. Any Lotek transmitters found to be defective, with respect to material, workmanship or warranty life, effective from shipment date, will be repaired or replaced.
Periodic design modifications to individual models may alter specifications. It is recommended that specifications be confirmed when placing an order.
