Great to hear that you are happy with the features of the Locator S1.
The Underwater GPS G2 has significant improvements on the acoustic signal transmitted and due to this the Locator S1 does unfortunately not work with the G2.
In order to support this the Locator S1 will need a new revision to be able to support the improved acoustic signal. We might do that moving forward, but nothing is planned in the short term. I’ve made a note of your interest in an updated version.
