Forerunner 945 HR

If you're looking to improve your athletic performance, nothing beats having quantifiable metrics to monitor and analyze your efforts both during and after your activity. Garmin's latest Forerunner 945 HR gives you and your coach the tools you need to have you performing at your best in a watch that's stylish enough to wear for every occasion. Add in the ability to sync music from streaming services or store up to 1,000 songs on your watch, and connect with headphones (sold separately) enabled with Bluetooth technology for phone-free listening and Garmin Pay allowing you to make convenient payments with your watch so you can leave your cash and cards at home and you have one of the smartest smartwatches on the market.

The new 945 gives you the ability to monitor multisports with ease, thanks to its built-in activity profiles for running (indoor/outdoor), cycling (indoor/outdoor), swimming (pool/open water), hiking, and others. It even has an auto multisport feature that lets you switch sports with a single button press for brick workouts and while transitioning during duathlon and triathlon races. Other features include barometric altimeter for tracking elevation changes, GPS, GLONASS, and Galileo sensors for tracking speed and distance, Garmin Elevate wrist-based heart rate, training status to determine if you're training productively, peaking, or overreaching, and lactate threshold and VO2 monitoring. Increased battery life allows you to train for longer between recharges, lasting up to 2 weeks in smartwatch mode, 10 hours in GPS mode with music, or up to 60 hours in UltraTrac mode.

Not only is it ideal for the tri sports of running, swimming, and cycling, but it also has features for cross-country skiing, paddle sports, trail runs, hikes, and golfing among others. To customize its use to your preferred outdoor activities, you can create tailored workouts with the Garmin Connect app (for both iPhone and Android). For additional cycling statistics, you can pair the Forerunner 945 with a powermeter.

Poor Product

  • Familiarity: I've put it through the wringer

I had read a few bad reviews for this watch, but more or less chalked it up to a mismatch between product and consumer. As it turns out this watch is inept at in all the places the 935 shined, except for maybe keeping the time...both perform equally well at that.

I was looking forward to this watch primarily because of the sp02 sensor, as I've been doing some higher elevation hikes/climbs, and wanted to utilize it on my Mt. Whitney day hike. Should have just taken my 935, as I couldn't even use the 945 to give me a decent distance traveled reading. Worst of all I couldn't trust the heart rate reading. Thankfully I'm pretty attune with my body, and could ballpark my status throughout the hike.

Sensor breakdown below:
- Battery life = mediocre (even with most of the sensors shut off)
- Long story short, the GPS is poor which takes it's toll on the elevation, compass, and distance monitors. Very frustrating.
- Elevation sensor - I had this watch 4 days and had to re-calibrate it multiple times each day to get a proper starting point
- Compass - same thing as the elevation sensor except I got tired of rotating my wrist in a figure 8 for 5 minutes, and eventually gave up trying with this.
- Heart rate sensor - It seemed to be fairly accurate when I wasn't in an activity, but when I either selected run, trail run, or hike the readings were significantly lower than my actual heart rate
- Activity distance (run, hike, trail hike) - was at least a mile off of the actual within 4 miles of starting the activity.
- Sp02 - it was all over the place. I got a couple readings at around 8000 feet that were 99%, then a couple that were in the 80s. Similar issue at higher elevation. Ended up having a 96% reading on the summit of Whitney, but I have no idea how accurate that was given the inconsistencies at the lower elevation checks.
