Descent MK1 First 24 hours - Impressions and Issues

So i received my shiny new device on Monday afternoon so wanted to share some first impressions.

First the positives:
- It’s light, looks very well made and is quite beautiful in terms of finish (I have the DLC titanium edition)
- The titanium band is very easy to adjust with screwed in link pins rather than push out so capsule be adjusted you most
- The screen is a big step up from the 3HR as is the performance
- GPS lock is faster than the 3HR and tracking looks about the same. I’m yet to try Glonass

Now initial frustrations
- On my one and only run I lost RD metrics half way through. I was using a HRM-Run (version 1) with up to date firmware and good battery. HR remained throughout (it was -2c so was wearing the watch over my jersey so no optical HR)
- My vectors do not seem fully supported. I can’t turn cycling dynamics off and on. I can do this with my Edge 1030 but don’t understabd when not supported yet
- Running power is not supported. Not sure why this is given it meets all the requirements

At times, it is better to turn off the Auto calibration and Manually calibrate the device.

Here is a useful article that will walk you through it. The article was made for the fenix 5 but the process and information are the same.

I will give it a try and see if that improves the accuracy. So any idea on why I get NO heart rate data after a dive when I am wearing the HRM-Tri sensor? And yes I have my Descent configured to use the strap and not the optical sensor. It does show HR data for before and after the dive, but nothing for when I am in the water. Sent this in to Garmin Tech Support but never got a response.

Yeah that is almost useless, reset it to 75 feet and an hour later it was reading over 2,700 feet. And I am not sure it is practical to expect people to manually reset the altitude every hour.

Mine doesn't do anything like that. At most it varies by a few to perhaps 10 metres.

It sounds like your Descent has a faulty sensor.

Maybe, my first one died after one night in the pool with an OW class.
