21 ▪ CARRY
The CARRY function lets you leap-frog the Measurement Module and Base
Unit to measure elevations (differential level) over any distance or elevation
on earth without tabulation, computations or loss of your original benchmark
plane. Two people working together can traverse terrain at a 2 mph (3 kph)
rate.
To use the CARRY function follow the steps in the illustration. Repeat the
HOLD and ZERO sequence over any distance or elevation. You may keep
the Base Unit vertical for ease of leap-frogging if it was vertical when setting
the benchmark.
To exit CARRY within any set-up, press and hold the ZERO key for two
seconds without the HOLD indicator showing. You can then do a new set-up
zero without loss of the CARRY benchmark and later re-enter CARRY by
pressing HOLD and then ZERO for 2 seconds without moving the Module.
You can preset the CARRY reference to any elevation such as at a survey-
ors benchmark using the ELEV function.

Can measure the height of a mountain or locate
an elevation across town – no pencil, paper or
calculator needed.
