I've used it in deep wooded areas and haven't lost signal yet

Suunto products catch a GPS signal almost immediately, and the ultra-modes work great for super long races.

Also, and this may be more of a subjective impression, but it seems like this model captures the GPS signal a bit faster than the old one; I know that when you do plug it into the computer (which you need to do for charging), data download from the watch and syncing with settings and updated satellite information is *much* faster than it used to be, and so far seems to occur with fewer hiccups

My phone was off 450m on the same run)Also, since the GPS is so good, the instant pace is also great (not as great as with a footpod but comparing to other gps units is way above)The watch has good amount of customization and shows really solid info on the watch itself after a workout
