The Escape203's accuracy and good usability in all conditions makes it an ideal companion for climbers, boaters and outdoor enthusiasts as well as for professionals. The altimeter of the Escape203 shows you your current altitude, vertical gain or loss from the start of a hike or climb, as well as your vertical ascent and descent rate in ft/h (m/h). Up to 20 altitude points can be stored into the memory for later reviewing. The one-logbook memory stores total vertical ascent/descent for the log, as well as the maximum and minimum altitudes reached during the activity. The unit also stores the accumulated vertical ascent/descent over a longer period of time. The altitude range extends up to 29 500 ft (9 000 m). The resolution is adjustable by the user to either 3ft (1 m) or 10 ft (5 m).
