Measuring all kinds of atmospheric data such as wind, temperature, altitude, barometric pressure and humidity is a matter of interest but can, in different situations be absolutely essential for the user. The ADC series (ADC Wind, ADC Summit and ADC Pro) are all specially constructed to meet the high demands. Featuring an air-pressure sensor on top of the functionality provided by the ADC Wind, this unit is the perfect companion when in the mountains and/or when an altitude/barometric pressure/weather tendency is required. The ADC Summit is designed for mountaineers, climbers, skiers (yes, it counts the number of ski runs as well!) and many others. Your performance data can be logged in the ADC Summit and downloaded through the ADC IR interface (optional accessory) to a PC. Same features as ADC Wind plus: Altitude (current, min and max) Altitude Alarm Cumulative ascend/descend Ski-run counter Current barometric pressure (mbar, hPa or inHg) and a past 24-hour barometric history Weather forecast in 5 levels (Sunny, Partly Cloudy, Cloudy, Rain, Storm Warning) Data log memory (automatic and/or manual) IR data communication using accessory ADC IR interface (optional extra)
