Why use a MicroTim Digital Altimeter instead of a wristwatch, GPS, or a (big heavy expensive delicate) analog altimeter? MicroTim altimeters are NOT slow-update small-readout devices such as in typical GPS units and wristwatch altimeters.
Extreme sensitivity. Registers changes in altitude of 2 feet or less. Try that with your expensive, heavy, large, and delicate analog altimeter or GPS unit!
Calibrated from -2000 feet MSL (2000 feet BELOW sealevel) to +20000 feet MSL (20000 feet ABOVE sealevel).
Low Power. Single AAA battery lasts for months. Battery monitor gives several DAYS of low-battery notice< to prevent being caught on a trip with a dead battery.
One foot resolution, barometric-pressure and field-elevation adustable.
AGL(relative), MSL(sealevel) or BOTH alternately every 2 seconds.
Selectable units: feet/inHg or meter/kPa or feet/mbar(hPa).
Excellent ultralight altimeter or backup unit. Very popular with ultralight pilots because of MicroTim's light weight, small size and vibration resistance. Small (3"x1.5"x3/4") with large easy-to-read numbers (3/8" high numbers). Moves easily from truck to pocket to ultralight. Very durable (resin encapsulated internals), resists shock, vibration, and moisture.
EASY TO USE right out of the box. The 3 primary key functions allow you to o 1) Raise the barometric pressure setting o 2) Lower the barometric pressure setting o 3) Zero the ground-level altitude (AGL)
Then three additional functions are accessed by holding down one key for 5 seconds which allows you to o 4) Change units o 5) Change the display mode ( AGL, MSL, or BOTH) o 6) Reset MicroTim to factory defaults (AGL only, feet, 29.92 inHg). ...and that's all there is to it!
