by 0

Garmin announce the expansion of its solar charging technology to the Instinct, fēnix 6 and 6S and tactix Delta adventure and multisport smartwatches.

Building on the success of the Garmin fēnix 6X – Pro Solar, the first solar charging multisport watch, these new editions offer a significantly increased battery life and new purpose-built functionality mountain biking, climbing activities and surfing.

The fēnix 6S Pro Solar and fēnix 6 Pro Solar are the newest editions to the multisport GPS smartwatch line. Features include Garmin Power Glass™ solar charging lens and a customisable Power Manager mode, using the power of the sun to stay on and remain performance-ready for weeks.

The usual training features, onboard mapping, music streaming are all there, with some new activity profiles including surf, mountain bike and indoor climb.

Mountain Bike

The new “Grit and Flow” activity allows users to track the details of every ride with mountain biking metrics, plus specialised measurements that rate trail difficulty and how smoothly the rider descends, giving a unique score to beat next time.

Indoor Climb

The indoor climb activity profile allows climbers to track their sessions at indoor facilities. Metrics include the number of routes, vertical distance climbed, climbing time, difficultly of each route and more.

    Coool! Thanks for that. For something seriously tough there is also the following from Casio G-Shock…

    cheers. happy trails

    “sufficient solar exposure” – I’m guessing that’s not under my sleeve and/or on a night ride, i.e., a fair number of my rides 🙂 We’ll see how my solar watch (not G-Shock, not at that price) fares.
    It’s good to see more solar things coming out; the less we rely on disposables the better.

    I bought an Instinct Solar last Friday, very satisfied with it so far. If I had a gripe it is that the screen is quite small which I presume is to accommodate the solar panel surrounding it. It is about 2/3 the size of the screen on my Garmin 310xt, the viewable screen size is 23mm x 23mm. The size means that it isn’t to chunky and can be worn as day to day watch, something I would never do with the 310xt. However the b&w screen is easy to read, white characters on a black background, even without my reading glasses. Loads of functionality, once you work out how to find your way around and links very nicely to my Samsung s8 phone, all the notifications go to the watch as well. One thing I need to watch is the drain on my phone battery while I am out which may be due to the constant connectivity to the watch. On Sunday I fully charged my phone before going out for a 4 hour ride with a 1 car journey each way, when I got home the phone was down to 10%! I also use the Life360 tracking app so my wife can see where I am in case of emergency (a hang over from solo rides during lock down) and I know that this app seems to be battery hungry, so coupled with the watch may be why the phoned drained so quickly. I will keep an eye on this. Can’t comment much on what difference the solar power makes, but fully charged the watch showed 22 days worth of power, after 4 days with being out in sunshine for 5 or 6 hours each day it is now showing 20 days worth of power.
