There's been a ton of fanfare today about Suunto's new sport watch, the Vertical. It has maps and amazing GPS accuracy and battery life. A couple of the reviews I've seen are here:
What watch do you all use? I've long used a Suunto on callouts (the 9 Baro -- that thing is bombproof!), but I've defaulted more to using a "dumb watch" if I anticipate being in a vertical environment for either missions or trainings ... something I can bang against the rocks while on the frog system or dropping down on a rescue 8 and not stress too much about it.
