We have just gotten the newest Jeti sensor– the MAlti. The MAlti is a new altitude sensor that uses the atmospheric pressure to calculate the distance above sea level, much like the MVario2. It is a great sensor if you need a basic altimeter. It measures three different parameters, air pressure, altitude, and the temperature of your sensor. The cost of the sensor will save you about 35 dollars from the MVario2. Click the link below to go to the product page.
