General Description
The LX-3 multicolor sonar unit utilizes three different colors within its display to differentiate between densities of objects. The Red light displays the strongest of return signals, often signi- fying a hard bottom or a larger fish that is often in the center of the transmit signal (cone). The Orange light displays the next in the line of weaker-signal returns, often signifying a softer bottom or smaller fish in the middle of the transmit signal or a larger fish on the outside of the transmit signal. The weakest return is dis- played by a Yellow light and often signifies weeds, small bait-fish, medium-sized fish on the outside of the transmit signal, or a very soft bottom. The use of different colors in defining return signals is meant to be informative in indicating the size of fish, type of bottom or location of weeds. The interpretation of these signals improves with experience and use in the field.
The LX-3 offers six levels of signal Interference Rejection (IR) that knock out signals from nearby competing units. This is most prevalent in ice-fishing applications where anglers utilizing sonar are often grouped together within small areas. The LX-3 offers a Zoom feature that allows the user to hone in on a specific sec- tion of water within the water column and, conversely, improve the ability to separate targets from 2.15 inches down to 1 inch. The Zoom window (area of water being selected) can be set at either 5 or 10 feet on the 20- and 40-foot depth range, 10 or 20 feet on the 80-foot depth range, or 20- or 40-feet on the 160-foot
depth range.
