Casio 2500

    Really like it. More durable than the Core, with more features, for less coin. If you're into bona fide mountaineering the Core is probably a better choice because of the barometer/altimeter lock, the Casios don't offer that. For general use and anything around water this little gem is hard to beat. Tons of accurate info in a nice package. The band is noticeably more comfortable than other Casio resin bands too. Happy hunting.

    how accurate is the altimeter?

    how accurate is the altimeter?

    The altimeter is accurate enough for hiking but not for mountaineering. The altimeter readings will 'drift' a bit as the barometric pressure moves, this is especially noticeable in the mornings b/c the elevation will have changed even though you've been sleeping. The Core's altimeter is more accurate and much better at eliminating the drift. The Core's altimeter logs and graphs are superior as well. If you need an ABC watch for vertical aspirations you'll probably be happier with a Core or Vector or Casio G-Shock Riseman.
