Important Notes

  1. Technical specifications are subject to change without notice.

  2. Sizes and weights are approximate and may vary due to manufacturing tolerance or component changes.

  3. Absolute accuracy of sensor, power consumption, generation rates, and the like are complex and in many cases dependent on operating conditions.  Instead of guaranteeing any specific accuracy or results, we conduct lab and field measurements and publish he data as it is for your review.  Please see these information sources:

    1. The SeaTag section of our knowledge base, contains various application notes and data sets providing field and lab performance measurements.

    2. A 'Calibration Report' is stored on each tag and is available through the SeaDock software

    3. A 'Sensor Test' function in SeaDock allows for instantaneous testing of your tags sensor functionality.
