POLAR Pacer Ultra-Light GPS Fitness Tracker Smartwatch for Runners; S-L, for Men or Women, Black

The battery lasts a little over 3 days hiking 12+ hrs a day which is why I bought this one. If you wear the H10 chest strap HR monitor this watch will automatically use that rather than the optical monitor as the H10 is more accurate.

This is a great watch. Gives me HR, pace, distance and total time and it's very accurate in each of those areas. It also gives me a ton of stuff I don't need but maybe others do, so I guess that's okay. The only thing is, it can be complicated to figure out how to do things quickly because there's a bit to remember even just to do the basics (I'm old, it's difficult :) ).I do have one comment related to something I've seen in other reviews. Several people have said the watch screen is hard to see, that it's too dark. If you play with the menu long enough you will find two different sections for screen brightness. One is for the brightness itself and you can set it at low, medium, or high. There's another menu where you can tell the watch to leave the screen brightness on permanently. When you do those two things, the screen is very easy to see, even in cloudy weather.All in all, a very good watch. I'm glad I bought it. The added ability of syncing with a 'diary' on the Polar Flow site to keep track of EVERYTHING is a great added bonus. I've even found out I'm sleeping good :)

I decided to upgrade to Polar Pacer, so far I'm very happy with my choice! I highly recommend this upgrade Polar Pacer fitness watch!

In about four months, the light started coming on during workouts when the device was set to backlight on button press only. It would take two button presses to turn it off (It should only take one, indicating a malfunction), and it usually came right back on after shutting it off. The light was just almost always on during workouts no matter what. I filled out an online form and sent it in for repair, paying shipping and making a trip to the post office. When I got it back two weeks later and started a workout, the light came on instantly. Apparently it wasn't even inspected. Adding insult to injury, the returned return contained an invoice for another customer, but not my invoice. I sent them two emails about this and haven't received a response (It's been 8 days since first email and 2 since second).Update: Sent it for repair a second time, and the main body was replaced, or at least the plastic case which has a new serial number. It had exactly the same problem which started immediately. Without any help from Polar I thought it might be a firmware problem and updated to version 2.0.12 with FlowSync on a PC, and the problem is completely solved.

I had a Polar M430 for years that finally broke and no replacement was available. I was beside myself as I had loved the watch so much. Finally broke down and purchased the Pacer and j am over the moo ! Lightweight, so easy to use, holds a charge for days and provides more than you could ever need in a running/fitness watch. Look no further...this is the watch you NEED!

Overall i think this is a good watch. It has A LOT of information for your fitness. I returned this item shortly after buy it because (1) the watch face is not very customizable, and (2) the screen is quite small for such a big watch, and (3) annoying to go into "activities" menu to see my step count. Because the watch face is not customizable, it gets annoying to go into "activities" menu every time when I want to see my steps. Again, nothing wrong with the watch. It's more of a personality thing for me. Also, I didn't need all the information that it provides, thus I went for a cheaper option.

As an athlete and soldier in the Army, i find this pacer to be amazing alongside polars chest heart rate monitor. It really helps me correlate my heart rate to my rate of exertion. I was an off and on runner before but now im trying to drop my 2 mile time and prepare for marathons and these two polar products are definitely helping me get that mind body connection that i was originally only used to from weight lifting.
