1. Selecting ID
Factory Setting: Fish Symbols
ID identifies targets not attached to the bottom
and displays them with either a fish symbol or an
arch. Three different size fish symbols are used
to represent the returned signal strength, a good
indicator of fish size. Use the up and down arrow
keys to switch between fish or arches, or use the
ON-OFF switch to disable ID.
2. Selecting Units
Factory Setting: MPH/SM
If you are using the trolling speed accessory
with your Platinum ID, you can switch the units
of measurement between miles per hour (MPH)
or knots (KTS). This selection also affects Trip
Log where recorded distance will be displayed
in statute miles (SM) or nautical miles (NM).
