Section 5: Ice Fishing
The M68C and the M68C IceMachine

work exactly alike. Each M68C
unit contains a menu command that allows you to switch the sonar in
and out of IceMachine mode. The only differences between the two pack-
ages are the accessories they are shipped with.
The IceMachine

package includes the M68C sonar unit and the PPP-15
portable power pack. The PPP-15 includes a self-leveling ice fishing
transducer, a rechargeable battery and charger, and a freeze-resistant
carry bag that fits inside a typical 5-gallon plastic bucket.
The regular M68C package includes the Skimmer

transom-mount
transducer with built-in temperature sensor. If you purchased a regular
M68C package, you can buy the PPP-15 separately. If you purchased an
IceMachine package, you can buy a Skimmer transducer separately with
mounts for transom, trolling motor or portable suction-cup installations.
NOTE:
Your unit is capable of accepting as many as two temperature sensors
during warm weather fishing. This is accomplished by using a Skim-
mer transducer with a built-in sensor for Temp 1 and an optional sec-
ond sensor for Temp 2. The ice fishing transducer does not contain a
temp sensor, so only one temperature reading can be displayed while
ice fishing. This requires the purchase of the optional TS-2U temp
sensor. This model has a fixed electronic address which designates it
as the second of two sensors. To display this temperature correctly,
from the Ice Flasher page, press

the Speed and Temperature Sensor entry in Sec. 2, Installation.
These accessory combinations and the unit's digital flashers and scrolling
chart display make the M68C the most versatile ice fishing sonar/GPS
unit in its class. Owning an M68C is like having a GPS and two fish
finders rolled into one, because it's equally at home on a boat in summer
or on the ice in winter.
This section covers the basic ice fishing functions. In addition to the in-
structions found here, be sure to read the PPP-15 instruction booklet,
part number 988-0147-871. It will tell you how to set up the ice fishing
power pack and mount the M68C.
