Polar Vantage series if you have the dosh.I have been curious about the GPS accuracy on Polars as i suspect that they're better watches than the Garmins I've had/got
I have a Spinsto and I think it's very hard to justify.
With the Garmins and Polars there is so much choice and you can't really go wrong, and you will get loads of features. The thing to note is that GPS accuracy with any watch when refereeing, because of all the turning, will not be reliably accurate. It's just not what they are designed for. Plenty of threads on this. Best guess is up to about plus/minus 15% depending on watch, tracking, mode, weather, satellite position etc etc.
some let you select which rate to use--higher sampling rates also run down batteries faster, so there is a trade off there.The biggest factor is the sampling rate. If you have one of the high end ones that takes your position every second it has a chance of being at least reasonably accurate, whereas those that sample at 5 seconds have no chance of being even close to accurate.
Can get a week out of a polar vantage with 1s sampling.some let you select which rate to use--higher sampling rates also run down batteries faster, so there is a trade off there.
I presume it isn't doing GPS sampling when you aren't running or some other tracking activity, right? I believe the GPS watches burn a lot more battery when active GPS than day to day use. (With my old Garmin vivoactive the only time I had battery issues was triple headers (i.e. R-AR-AR)--needed almost a full charge to get through with the GPS on. But otherwise going a week on a charge was normal. Alas, I still haven't been able to use my new one. I don't recall what the sampling is--I think it has choices, but I'm too lazy to go back and figure it out.)Can get a week out of a polar vantage with 1s sampling.

Triple headers would be no issue.. Polar reckon they can get about 40 hours training to a charge. Not an unbelievable figure. I have 247 HRM, tracks steps and sleep tracking. Have done 3 games in a week and a couple of runs/walks in between from one charge.I presume it isn't doing GPS sampling when you aren't running or some other tracking activity, right?

I used to track 2 40 min dog walks a day as well on top of training. Always get roughly a week consistently no matter what I do.
My Garmin 245 music is quite new and I've been astounded by the battery life so far. It also charges very quickly, always faster than I expect.Hmm. I'm curious what the newer Garmin will do. But I'm sure not expecting 40 hours of GPS based activity.
