[. . . ] NOTE: Your unit is capable of accepting as many as two temperature sensors during warm weather fishing. This is accomplished by using a Skimmer transducer with a built-in sensor for Temp 1 and an optional second 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 MENU| to OVERLAY DATA|ENT. For more information and figures showing sensor configurations, see the Speed and Temperature Sensor entry in Sec. 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 instructions 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. Introduction to IceMachine Mode Your unit has five pages that display sonar information. In addition to Full Sonar Chart, Split Zoom Sonar Chart, Digital Data and Flasher, 67 there is the Ice Flasher. This page is only visible in IceMachine Mode. You can tell at a glance which mode you are in because the battery gauge only appears in the lower right corner of the Ice Flasher page. Ice Flasher page, left, and normal Flasher page, right. The ice mode differs from normal mode in two ways. First, the unit changes how it filters incoming sonar echoes. This helps reduce some of the surface clutter that can be picked up from the zone where the water surface meets the bottom of the ice. Second, the Ice Flasher defaults to a special IceView color mode with fewer, higher-contrast colors than normal mode. This simplified color scheme makes it easier to "see" and interpret a fish signal when it appears on the flasher screen. The Split Zoom and Sonar Chart pages share the same settings. The chart pages, the Flasher and Ice Flasher pages each have their own independent controls for Sensitivity, ColorLine and sonar color mode. For example, if you make any Sensitivity changes to the sonar chart page, the sensitivity settings for the Flasher and Ice Flasher are unchanged.
