I didnt have issue except my last night run with fr970. I had run 30-40 minutes with full open flashlight in the night so when i finished and wanted to record my run it just stopped for 15-20 minutes. No to control and anythings just stopped and this maybe you should not full open flash while running. But it weird because its garmin feature so frustrating facing garmin stop end of running.
Have you tried an AMOLED watch? Since getting a 970 I would never go back to MIPs. Only negative is battery life. But that’s not really a big deal for me.
Congrats dude! I have owned both the 970 and Pace Pro, each has their pros and cons. The 970 definitely feels a bit more premium in the hand and on the wrist. The flashlight feature was helpful in some cases too. I ended up sticking with the Pace Pro, though. The better build quality and flashlight wasn't worth the extra $400 to me. That's not to say that the Pace Pro feels cheap either. Garmin had more smartwatch features, but I didn't use them all that much. The extra metrics I didn't find useful. The Pace Pro lacks in smartwatch features, but if that doesn't matter to you, it's a great running watch. Less metrics, but it has all necessary ones (at least for me). Also, the Pace Pro is lighter than the 970, if that matters to you when you run. I also much preferred the Coros app compared to Garmin Connect. I also used some of the accessories for each watch. The Coros heart rate monitor armband was much more comfortable to me than the Garmin HRM chest strap. It also was just about as accurate as the chest strap for me. Both are great running watches, can't go wrong with either. Just depends on what features you value. Good luck and enjoy your new watch!
Just my two cents (just came from a seven year old forerunner previously) but I actually returned my Venu 4 and am buying a 970 soon. I missed the buttons, that simple. That said, Venu 4 is an absolutely fantastic watch. For your purposes coming from an Applewatch, it seems like a no brainer. If you can live without the buttons and the more hyper detailed running metrics (which I don’t really even need), Venu 4 is FANTASTIC.
I’m with you…. every time a new AW would come out, I’d upgrade, primarily for the better battery life. Last one I had (just sold it) was an AW Ultra 2. The more I used it, the more I realized I was primarily using it for cycling workouts and weekend rides. Did a boatload of researching and picked a Fenix 8 (got a nice deal on a barely-used one of off eBay)…. should be hear by Saturday :)) From what I understand so far, there is truly a ton of metrics that the Garmin’s track. Sensor, from what I’ve read, is pretty solid - but like anything, a HR strap would be better if you want the most accurate reading(s) - same goes for any AW. Another you should consider - the FR 970. Definitely a little more stylish than the Fenix lineup. Different strokes for…. well, you know the rest ;) Good luck!
I bought 970 and 265. 970 was too heavy and bulky. 265 is so light and disappears with the ultra velcro strap. It has a screen flashlight which I still find useful at 5am indoors but is not very useful otherwise. 970 light is badass, but not worth the extra heft and cost.
