− There are two options for measuring depth. 

Live depth is a continuous measurement. 

1-Shot Depth is an averaging of the depth 

reading over a short period of time. When in 

1-Shot mode, the unit will average the depth 

reading for three seconds, and then display 

the result on the display. Press Depth [SK] to 

alternate between the two modes.

 

− Five depth readings can be saved with the 

time, date and relative current measurements.

3.  Pressing Save [SK] will place each entry in sequential order in memory (M1 - M5) 

until five readings have been stored. The unit will overwrite saved entries in excess 

of five, beginning with M1.

4.  Press Clear All [SK] to delete all stored depth 

information.

 

− The operator may select the memory location 

to store the depth readings by pressing Mem 

Select [SK]. When the preferred location
