GPSMAP H1 – Inconsistent Approaching Alarms

empe

I noticed several months ago that the Proximity Alarm feature was not working reliably on my GPSMAP H1, but I did not investigate further because the behaviour seemed inconsistent.

In the past, I experienced cases where, after one expected proximity alarm failed to trigger, no further proximity alarms were triggered for the remainder of the activity. During today's walk, however, the behaviour was different: one alarm was missed, but subsequent alarms worked again.

I also received off-course alerts even though the recorded track followed the navigation line exactly. Navigation was running without routing.

I have not been able to identify a reproducible pattern so far. Any experiences or explanations from other GPSMAP H1 users would be appreciated.

    In today's separate test, I used the same A–B course, planned in Garmin Explore, for two activities: once with routing enabled and once with routing disabled.

    The course contained shaping points that had been converted into waypoints.

    Once again, I encountered inconsistent Approaching Alarms:

    • In one activity, no alarm was triggered at the first waypoint.

    • In the other activity, no alarm was triggered at the second waypoint.

    The missing alarms therefore occurred at different waypoints, despite using the same course and waypoint setup, with routing being the only difference in the navigation settings.

    Hello  I can understand the concern. I would love to help investigate this. For this, I will reach out to you via email to collect details for this concern.
