How useful are the voice commands?

How useful are the voice commands for (navigation, hiking, paddling, skiing)...

The main reason why I'm considering voice command feature:

  • When both hands are busy (paddling/sailing), I don't want to stop what I'm doing to press buttons.
  • If I'm wearing gloves, I don't want to remove gloves, push buttons/screen, don gloves.
  • I don't want to remember or navigate the menus (I don't now how complicated or deep the menus go).  I also don't like wasting time during my activity navigating around the UI like I do on my phone app.

I don't have a watch, just my phone, so I have no idea how Garmin Fenix watches work.  I've read the manual, but I can't determine how the UI or voice commands, or buttons/touch, actually are used.

Navigation:

Start/stop/pause navigation.

Record track.

Add place marker.

Add voice-to-text notes to:  marker, track, navigation, trail, segment, etc.

Show map.

Switch between different map/information views for hiking, rivers, nautical (map, slope, elevation gain, distance, time, speed, ETA).

Water:

Show me tide info.

Common:

Show me weather (I saw this in the manual).
