Thermoclines
A rough defi nition of a thermocline is a break in water where the
water temperature changes at a faster rate than the water above it. The
thermocline is usually displayed as a gray level, as shown below.
One of the unique features offered by GARMIN is See-Thru technology.
A benefit of See-Thru technology is that it allows the Fishfinder 160 Blue
to see fish inside thermoclines.
