Founded in 1965, Vexilar, Inc. has a long history of bringing revolutionary technology to the sport fishing industry. Just some of the Vexilar firsts include: the first liquid crystal display, the first fish alarm, the first three color display, and the first CRT and straight...
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.
Replace the compartment door and tighten the screws back into place. Make sure that the power cord from the battery pack is plugged into the bottom (3 pin) jack on the LC-10 and that the retaining ring is screwed down tight.

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 per- manently mounting the transducer bracket to the boat.
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.

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. Attach the angle bracket to the transducer (flat edge facing forward).

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 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.

Let the glue dry completely before turning the unit PERMANENT MOUNTING (Optional) You can permanently mount the LC-10 to your boat, yet maintain the easy portability for times when you go fish- ing in another boat. You will need to have a battery in your boat to power the unit.
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...

Press the FISH ID ON/OFF button to turn the fish iden- tification feature on or off. When the feature is on, any tar- get that the LC-10 sees will be judged as to whether or not it is a fish. If the unit determines that there is a good chance the target is a fish it will display a fish shaped symbol on the display.

ON. This doubles the display res- olution 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.
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.

SIMULATOR There is a built-in simulator that will allow you to oper- ate the LC-10 without being on the water. To activate it, turn the unit off. Then, press the ON/OFF button and hold it until you hear a second set of beeps. You can then let go...
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, depend- ing 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.

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.

It often helps to turn off the AUTO feature and manu- ally change the range to the 5 or 10 foot range. This tells the LC-10 that you are in shallow water and it will adjust the gain appropriately. If the digital depth reading doesn't seem right, it is probably a multiple of the correct depth.

ICE FISHING The stable platform of ice lets you concentrate on your bait and the fish around it. The bottom becomes less impor- tant 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 trans- ducer is pointed is very critical.
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.
