Anyone tried to replace their handheld GPS with a GPS watch like a Suunto or Garmin? This topic hasn't been visited in a few years here as far as I can tell based on my search. I want to buy a GPS unit, but don't want to carry another "gadget" with me in the field. I have a decent app on my smartphone, but I don't think it is as good as a real handheld GPS unit. I wear a G-Shock watch anyways so replacing with a smart watch wouldn't be any extra burden. Seems like GPS watches are getting close, but can't quite replace a handheld. What do you guys think? I think if I wait a year or 2 I will probably be able to get a watch that does most of what today's handheld units can do. Worth waiting?
