This multifunction barometer/altimeter/thermometer/clock puts a huge amount of information in the palm of your hand. Use the barometer to determine the current pressure at a resolution of 0.1 mBar, and check out previous minimum/maximum atmospheric pressure, along with pressure trend indicators and 12 hours of history. Get your altitude up to 9000 m with a resolution of 1 meter, and recall the last 12 hours of altitude data in an easy-to-read graphical format. Set an alarm when you reach a certain altitude. Keep track of time with the clock. Thermometer stores the minimum and maximum values. Pyle Sports: recreational gear for the great outdoors!Arm yourself with information the next time you head out for a hike or climb with the Pyle Sports PAH1, which combines a digital barometer, altimeter, thermometer, and clock in a single palm-sized device. Use the barometer to get a feel for the weather, including the current atmospheric pressure at a resolution of 0.1 mBar, the minimum and maximum pressure, and pressure trend indicators for the last 12 hours. The altimeter measures your altitude up to 29,500 feet (with a resolution of 1 foot), in addition to recalling the last 12 hours of altitude data in an easy-to-read graphical format. You can also set an alarm when you reach a certain altitude, so you’ll know when to slow down and acclimate. And every hiker can use a thermometer, which offers a temperature range of -4 to 140 degrees F.

Other features include an ultra-reliable clock, a single daily alarm, and a lanyard.

The PAH1 fits in the palm of your hand or around your neck. Specifications
