A Deep Dive Into The Garmin Fenix 3

The Garmin Fenix range has been an outstanding line-up of outdoor adventure watches since they were first released.

You can trust Garmin to innovate and improve on an already successful product and that’s precisely what they’ve done here with the Garmin Fenix 3 HR.

Garmin have taken the previous Fenix 3 – popped it in a robust sapphire crystal display – more importantly – they’ve added Garmin Elevate OFF the WRIST heart rate sensor. 

Garmin have also given it some great new strap styles and added 3 new sports profiles > golf, stand up paddleboarding & rowing. On top of that they’ve included the latest advanced running dynamics and physiological measurements and even. The Garmin Fenix 3 HR has been reviewed by Tristan Haskins aka CardioCritic

Videos (Garmin’s own)

Garmin say “True performance meets true style. Introducing fēnix 3 HR. The rugged, capable and smart multisport training GPS watch with wrist-based heart rate. Let the journey begin…..”

I prefer this video demonstration for a proper idea of what the Fenix 3 HR can actually do ..

And this one gives some good examples of Heart Rate related screen views …

GPS & Glonass Navigation

Navigate GPX routes with clearly visible waypoints and breadcrumb trail showing your desired path. Routes can either be downloaded from GPX sources or you can built your own on Garmin Connect website.

fēnix 3 HR provides comprehensive navigation and tracking functionalities to guide you on and off the beaten path using GPS plus ABC (altimeter, barometer and compass).

TracBack feature navigates you back to your starting point the same way you came. Its built-in sensors provide information on heading, elevation and weather changes

Barometric Pressure sensor

The built-in altimeter provides elevation data to accurately monitor ascent and descent, while the barometer can be used to predict weather changes by showing short-term trends in air pressure. The 3-axis electronic compass keeps your bearing whether you’re moving or not.

Note > The Garmin Fenix 5 was released in March 2017. Same great functionality with wrist based HR and 3 x sized cases and enhanced fitness monitoring.

Smartphone Notifications

Love them or hate them, smartphone notification alerts can be very useful. The Fenix 3 will alert you to incoming calls, texts etc.

5 x Heart Rate Training Zones

The Fenix 3 HR is a great sports watch for anyone involved in serious heart rate training. With 5 x auto-set heart rate training zones see at a glance which zone you are in. Your training zones can be personalised if you want to set them yourself.

If you’ve not used a heart rate monitor before please try our heart rate zone calculator to get an idea of your own training zones. The clear colour coded heart rate display of the Fenix 3 HR also makes it a great watch for HiiT training.

24/7 Heart Rate Monitoring

Like the Forerunner 235 and Vivoactive HR the Fenix 3 HR samples your heart rate every 4 minutes (approx). Get a clear view of your peaks and troughs throughout the day.

As well as this 4 hour view it is also possible to recall a 7 day HRH graph.

This graph shows your daily average resting heart rate. Periods of extended elevated heart rate could be an indication of over exertion, illness or over training.

Top Alternatives

Next Model UP

The Garmin Forerunner 935 aimed at elite athletes in all disciplines including Triathlon provides some of the very best training feedback with Training Load, Training Effect (aerobic and anaerobic) and Training Status.

The 935 features a barometric pressure sensor but lacks some of the navigational features found on the Fenix range (e.g. route follow)

Garmin Forerunner 935 review – the best all round GPS sports watch for those not interested in GPX route navigation

Next Model DOWN

The next model down is the same watch, the Garmin Fenix 3, without the built-in Heart Rate. Personally, if I was spending this much money I’d get this one – the Fenix 3 HR. However, if there are some great deals on the regular chest strap version then go for it

Garmin Fenix 3 review – without Garmin Elevate off the wrist heart rate.

Closest Competitor

It’s difficult to recommend a direct alternative to the Garmin Fenix 3 as it depends on the features / functions that attracted you to it. Watches that come closest to the Fenix 3 are the Suunto Spartan range of GPS sports watches.

If it’s primarily for sports use and your racing time is under 9 hours then there is the Spartan Sport Wrist HR – also with wrist based heart rate For those looking for a fully featured ABC outdoor adventure racing watch it would have to be the Spartan Sport Ultra (currently not available with wrist based HR, but I am certain coming very soon ….) [April 2017]

Suunto Spartan Sport review – best suited to triathletes and other multisport exercisers – this version requires a chest strap
Spartan Sport Wrist HR review – best suited to triathletes and other multisport exercisers – also features off the wrist heart rate
Suunto Spartan Ultra review -best suited to outdoor adventure racers and ultra marathon / Ironman – chest strap required
