Altitron (Wrist Mount)

This digital altimeter logs information for 300 jumps, including jump number, date, time of day, temperature, exit and deployment altitudes, freefall time, maximum and average freefall speeds, and time and maximum speed under open canopy. You can set it for takeoff and landing at different altitudes too. The Altitron features handy backlighting and uses a simple AAA battery.
