GENERAL DESCRIPTION The Boundary Waters model LC-10 is a compact and light-weight liquid crystal depth sounder. It indicates depth, shows changes in bottom content, and conditions. It can also discriminate between large underwater targets, such as fish, and smaller targets such as bait fish and plankton. The unit transmits bursts of high frequency pulses which are converted from electrical to mechanical energy by the transducer.

ASSEMBLY Set the battery tray down and place the unit, face down, inside. Line up the bracket holes and install the gimbal knobs. Make sure the rubber washers are in place. Turn the knobs in, but tighten only slightly. INSTALLING THE BATTERIES Turn the unit over to access the battery compartment door. Unscrew the two retaining screws and remove the compartment door. The screws are restricted from falling out so you don't need to worry about losing them.
ASSEMBLING THE TRANSDUCER Locate the transducer and bracket assembly. This includes: 1 - Transducer 1 - Metal angle bracket 1 - Suction cup 1 - Short panhead screw 2 - Short machine screws 2 - Nuts 2 - Washers 2 - Long panhead screws 1 - Safety rope The two longer wood screws, if included, are for permanently mounting the transducer bracket to the boat. They do not apply here. The suction cup installs using the single short screw. Attach it to the slot in the angle bracket.
Now locate the transducer and the remaining hardware. Install the transducer onto the angle bracket. The flat edge of the transducer should be facing the boat. Install the two short screws through the transducer slots and into the angle bracket slots. Place the washers and then the nuts onto the screws and tighten, only slightly. Slide the transducer up and forward in the bracket as far as it will go and then tighten the screws firmly. Finally, install the safety rope.
may need to purchase the optional Tri-Cup bracket shown in figure 6. ALTERNATE TRANSDUCER MOUNTING Figure 6 If you choose not to use the suction cup mounting method, you can permanently mount the transducer to your boat. This can, often, give better results, but you will lose the portability of the transducer. TRANSOM MOUNTING The LC-10 transducer can be mounted, permanently, on the transom of the boat. Proper installation will allow a clear depth reading at any boat speed.
Drill out the hole, install one screw, and tighten the bracket down securely. Be sure to seal any holes drilled into the transom with silicone to prevent water from leaking into the boat. Figure 7 If you have trouble keeping a clear reading, try tilting the transducer in the bracket so that the back, rounded, edge is slightly lower than the front, straight, edge. If readings are still not clear, adjust the bracket on the boat downward until the reading becomes clear.
idea to make a "test run" before you permanently install the transducer to make sure that you can indeed get a reading through your hull and at all speeds. Put about a half inch of water in the bottom of the boat and hold the transducer in the intended location. Move the transducer around until you get the best reading. Mark the spot. To install the transducer, first clean the spot of mud and oil.
OPERATION Figure 9 shows the main controls of the LC-10. ON/OFF Turns the LC-10 ON and OFF. Simply turning the unit on will start the Automatic System. This will give good results in most conditions. If you choose to modify any of the control features, your settings will be saved in memory when the unit is turned off. When you turn it on again the unit will operate the same way as it did when you last used it. Figure 9 AUTO Press the AUTO button to turn on or off the automatic range control feature.
RANGE CONTROL The two buttons at the top right of the control panel set the depth range when the Auto Mode is off. Pressing the SHALLOW button changes the range to the next shallowest range. Pressing the DEEP button changes the range to the next deeper range. LIGHT ON/OFF Press the LIGHT ON/OFF button to turn on the Backlight. Press it again to turn the backlight off. NOTE The backlight will double the current requirement of the LC-10, thus cutting your battery life in half.
EXPANSION EXP. ON/OFF displays only the bottom half of the water depth when selected to ON. This doubles the display resolution making it much easier to see targets near or on the bottom. Pressing the EXP. ON/OFF button once puts the LC-10 in EXPANSION mode. Pressing it again will go back to the normal view. MENU Pressing the MENU button opens the menu page. Pressing it again will go back to the normal view. Each item in the menu will be explained in the next section.
MENU FUNCTIONS SWEEP Press the MENU button and then the LIGHT button to enter the SWEEP settings. SWEEP controls how fast the information moves across the display. There are 4 steps of sweep speed. The top selection, four arrows, is the fastest setting. The bottom selection, one arrow, is the slowest. The sweep speed should roughly match the boat speed to get the most accurate reading. Press the MENU button to resume to the normal view.
TEMP ADJ Press the MENU button and then the ALARM button to enter the TEMP ADJ settings. This page allows you to adjust or calibrate the temperature reading if you have the optional temperature probe installed on your LC-10. Pressing the LIGHT button will decrease the read temperature by one tenth of a degree each time you press it. Pressing the FISH ID button will increase the reading. RESET Press the MENU button and then the EXP. button to enter the system reset setting.
Typical Indications Once the boat is in the water and you have turned on the LC-10 you must allow it time to find the bottom. This can take just a short moment or several minutes, depending on the depth and conditions. As soon as the digital depth appears the graphical representation of the bottom will start to move across the screen. The appearance of the bottom signal can give you information as to what type of bottom you are over.
SEEING FISH With the FISH ID feature on, any target that the LC-10 identifies as a fish will change to a fish symbol shortly after it appears on the screen. With the FISH ID feature off, the Clean Line feature will help you identify fish from floating debris. If the target appears cleaned out, you can assume it's something significant, like a fish. In heavy weeds this can be difficult to see. It is best to use the Fish ID feature in these conditions.
behind the transom. If your transducer is poorly mounted, the unit will lose the bottom at a certain boat speed. This is due to all of the air bubbles in the turbulent water. Readjustment of the transducer mounting should solve this problem. SHALLOW WATER OPERATION When the LC-10 is in the AUTO mode, it automatically senses the bottoms depth and tries to keep the best view at all times.
ICE FISHING The stable platform of ice lets you concentrate on your bait and the fish around it. The bottom becomes less important because it never changes. The only movement on the display is of your bait and fish. Unlike open water use, the direction in which the transducer is pointed is very critical. You want your bait to be located in the dead center of the cone sound, directly under the transducer. This way you can see very small baits at low gain settings and also see fish come in from all sides.
MAINTENANCE Maintenance for the Boundary Waters LC-10 is very simple. There, simply, is not that much to maintain. Because of this, problems can sneak up on you if you're not careful. The unit and transducer should be removed whenever the boat is parked to guard against theft. Don't store it in a place that may fill with water. Power connections need constant checking. Corrosion can develop and cause intermittent or loss of operation.
TROUBLE SHOOTING Symptom Possible Cause Unit will not turn on. Check for proper battery polarity and that you have fully charged, working batteries. Unit is turned on, but there is no display. Battery voltage may be too low. The unit will show no display if the voltage is below 8.5 volts. Unit runs well for a short time, then the unit quits. Bad battery. Voltage may be good when checked, but may fall as it is loaded. Unit runs and shows display light, but does not read depth.
