This allows for a larger Zoom window to be viewed on the deeper range settings. The Zoom window can be moved anywhere between the surface and the bottom by use of the UP / DN arrow keys located on the keypad. The LX-3 is offered with any one of three different twenty-degree (cone angle) transducers. The puck-style transducer is often used for mounting on the bottom of trolling motors or for in-hull applications.
Attach the mounting hardware to the high-speed transducer as shown in the instructions included with the transducer. Hold the transducer with attached mounting hardware to the transom of the boat (flush to the bottom) and mark the center of the holes on the transom. Drill the appropriate-size holes and attach the transducer to the transom. Tilt the rear of the transducer between 2 to 5 degrees below the transom to ensure solid contact with the water when the boat is on plane.
We cannot emphasize this strongly enough. Too much Gain will only clutter the display with unnecessary information, making it more difficult to interpret the return signals. Keeping the Gain at minimum levels will actually provide you with the most accurate and precise information. Interference Rejection - The Signal Interference Rejection system is designed to knock out competing return signals from other sonar units being used within close proximity.
To check the location, press either the UP key or the DN key to activate the visual blinking lights to reacquaint yourself with the location. The blinking yellow lights only assist you in setting the location and act as a visual reference. The benefit to the MarCum design is that it allows you to move your Zoom window between surface and bottom, and in turn Zoom in on any 5- or 10-foot section of water (on the 20-foot depth Range).
Signal Interpretation Hard-bottom readings (rock or gravel) will be displayed by a wide band of RED light indicating a strong return signal. Conversely, a soft bottom (mud or silt) will return a weaker signal and will result in a narrower RED band or possibly even a combined RED and ORANGE band. A soft bottom with weed growth will often appear as a narrow RED or ORANGE band combined with both solid and broken YELLOW segments indicating weeds.
each time you move locations, depending on the depth and bottom composition. Signal Interpretation - Sound waves emitted by the LX-3 bounce off targets and return with the strength of the targets’ density. Denser targets return with a stronger signal, displayed as RED. Less-dense objects (small fish) return a mediumstrength signal, displayed as ORANGE. The least dense objects (weeds, bait-fish, lure) return a weak signal, displayed as YELLOW. Objects on the edge of the sound cone may appear as yellow.
Two-Year Warranty For two years from original date of purchase, all required repairs resulting from manufacturing defects on your MarCum LX-3 will be free of charge. This does not apply to physical damage resulting from accident or misuse. Any modification or attempt to repair the original equipment or accessories by unauthorized personnel will void the warranty.
