Hand-Held Electronic Altimeter-Barometer

The Suunto Escape203 is an electronic hand-held watch-altimeter-barometer instrument with a memory. 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.

Altimeter
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).

Barometer
The Escape203 barometer keeps you ahead of the storm and shows the current absolute and sea level pressures, temperature as well as the barometric trend for the last 6 hours. The Escape203 features also a pressure alarm. In activated state the alarm will alert the user to pressure changes of 4 mbar/0.10 inHg over a period of 3 hours. A special feature of the Escape203 is a "locking mechanism" that keeps the altitude from changing when the unit is used for weather monitoring purposes only. Similarly, when the device is used as altimeter, the seal level pressure stays constant and the barometric changes only affect the altitude and absolute pressure reading. The resolution of the barometer is 1 mbar/0.05 inHg.

The barometer memory automatically stores the barometric pressure and temperature history for the last 24 hours, as well as the maximum and minimum values during this time. It also stores the maximum and minimum pressure and temperature values over time, which makes it valuable for estimating the barometric trend.

Watch
In addition, the Escape203 has a time mode with normal watch functions such as current time with 12/24 hour format, weekday and date.
The luminous display and user-replaceable battery makes the Escape203 suitable even for harsh conditions. Its operating with three buttons is easy even when wearing gloves. The unit is water resistant and temperature compensated. Neck lanyard comes as standard. The Escape203 device is light and ergonomically comfortable, weighing appr. 55 g.
