Anyone upgrading to the 5S or 5 from the 3HR? If so, why?

For me. 5 and 5s do not make sense as they offer little news for a f3hr owner. But likely I will get the 5x due to TOPO maps and route planning.
I travel a lot and it is a nice option to go out from the hotel and press "I want to run 10K"...no local area knowledge needed

Personally I don't see a reason to go from the 3HR to a 5 or 5S unless you're looking for a slimmer/sleeker looking version. If (when) I upgrade it'll be the 5X.

I agree the 5X, for the mapping, would be a worthwhile upgrade if someone wants mapping but I am thinking along the lines of you both, that the 5 is not really worth it.. I can see maybe the 5S if someone wants a smaller watch but I am one of the few who do not mind the 3HR size...

I think my preorder was based on new toy lust alone and not on weather or not it's worthwhile.. I still have plenty of time to cancel my preorder of the 5 and I am definitely leaning towards doing that.

My 3HR works fine and I don't have any issues with it at all. It's also in pretty good condition, all things considered...

My wife thinks they should impose a mandatory 3-week waiting period.

"There shall be a mandatory 3-week waiting period, which shall be three weeks, excluding weekends and legal holidays, between the purchase and the delivery at retail of any Garmin device. 'Purchase' means the transfer of money or other valuable consideration to the retailer.

I will be purchasing either the 5X or the 5 when they are released. Over a four month period (Sept-Dec 2016) I purchased 4 different 3HR's, and all were returned due to the well-documented altimeter/barometer issue. Three of these watches came from retail shops in two different States and the fourth came directly from Garmin Support. I loved the watch and all functions other than the malfuntioning altimeter/barometer. I have a long positive history of owning and using Gamin Forerunner and Edge devices, but due to the time period this 3HR issue has been recognized and not corrected, I lost confidence that Garmin is going to be able remedy this issue with new firmware. However, due to my past successful history with Garmin, I am optimistic that the 5's well work as advertised and am looking forward to purchasing one upon their release.

Hahaha... But kind of true!

I have not had the issue at all on my 3HR..

I just preordered the 5. Currently wearing the 3HR daily. I just want something a little smaller and I like new devices. It's not worth the upgrade monetarily I imagine, bit it has a couple of new and interesting features and it will be a fun new toy.
I was going to wait and see it in a store before purchasing, but my impatience got the better of me.

I watch the video the 3 is like the 5x.

I always sell my smart phone and get the next one, even if it is 1 yr old. Life is too short.

I am going to get the 5 Sapphire and sell my Edge 520.

We all have our opinions, but every time I think about going to a watch from an Edge for cycling I always end up back with an Edge device.

The data fields and screen size of the pure cycling devices is a big advantage over any of the multi-sport watches. My 310, 910, 920, and now F3 always ended up being running+swimming watches with a side of multi-sport when doing a race or brick (still using the edge during the race, but capturing the whole event with the watch).

Otherwise...

I too debate the advantages of the f5.
-I like the idea of a BT hr support (and possibly more later), but really all my stuff is either dual or ANT+ at the moment.
-The newer processor and memory for new CIQ is nice, but I never fell into CIQ apps or widgets anyway.
-I have the F3, so optical HR is possibly nice for resting, etc... but when I wore my wife's vivoactive HR for a week I didn't feel it gave me much
-Strava segments running could be fun?
-Size may be nice, my biggest gripe on the fenix series is how bulky and thick they are (more the thick than bulky, but both are too much). If I went with a f5 I think I'd do the 5S, but it still looks nearly as chunky thick as the f3.

Negatives:
-If I go non-sapphire, I lose wifi. I rarely use it, but now and then BLE sync seems stuck and wifi is my main way to fix it.
-Cost
-Potential new bugs to work through

I question if one could get $400 for a f3hr, and assume an f3 is more like $200-$250 used... so for me ~$350 for a new device is pushing it. If it were $499 rather than $599 I think I'd bite.

... Then again theirs leaked rumors of a 935 coming soon with optical HR enabled while swimming... if it has a barometric altimeter it may catch my eye :)

Wow - the feature to set a distance you want to run and have it calculate a route looks awesome. Did not see that before I pre-ordered the Fenix 5.... May yet be changing my pre-order.
