Fish I.D. is an easier way for a sonar novice to recognize a fishy signal
return when he sees it. However, locating fish by symbol
only has some
limitations.
Your sonar unit's microcomputer is sophisticated, but it can be fooled. It
can't distinguish between fish and other suspended objects such as
trotlines, turtles, submerged floats, air bubbles, etc. Individual tree limbs
extending outward from a group of limbs are the hardest objects for the
Fish I.D. feature to distinguish from fish.
To see what's under your boat in maximum detail, we recommend you
turn off Fish I.D. and begin learning to interpret fish arches.
You may see Fish I.D. symbols on the screen when actually, there are no fish.
The reverse is also true — Fish I.D. can actually miss fish that are present.
Does that mean Fish I.D. is broken? No — the feature is simply
interpreting sonar returns in a specific way to help take some of the work
out of reading the screen. Remember: Fish I.D. is one of the many tools
we provide so you can analyze your sonar returns for maximum fish
finding information. This and other features can help you successfully
"see" beneath the boat under varied water and fishing conditions. So,
practice with the unit in both the Fish I.D. mode and without to become
more familiar with the feature. This unit's default Fish I.D. setting is off.
Fish I.D. is most handy when you're in another part of the boat or
performing some task that prevents you from watching the sonar
screen. Then, you can turn on Fish I.D. and the audible
FISH ALARM
.
When that lunker swims under your boat, you'll hear it!
Fish I.D. can also be useful when you want to screen out some of the
sonar detail gathered by your unit. For example, it can help cut through
the clutter of suspended bubbles caused by wave action or boat wakes.
