7.Remove the water and transducer and clean the marked area and the bottom of the transducer thoroughly.

8.Using the Humminbird Epoxy Kit or equivalent, mix an ample amount of epoxy without causing it to bubble and pour it in the area the transducer is to be mounted. The puddle should be larger than the bottom of the transducer.

9.Coat the bottom of the transducer with epoxy, then put it in the center of the puddle and push down on the transducer while moving it around in a circular motion. This forces out any air bubbles that may be trapped between the bottom of the transducer and the hull of the boat.

10.Let epoxy cure then the transducer is ready to operate. No water is now required in the bottom of the boat and gas and oil that is spilled inside of the boat will not degrade performance as it will if the transducer is placed only in water.

CAUTION: Do not use the silicone seal or any soft adhesive to bond the transducer to the hull. This will reduce the sensitivity of the unit.

CAUTIONS

1.Occasionally the “eye“ of your transducer may become dirty from storage or from contact with oils present in boats or marina environments. (Oil will cause the “eye” to lose the intimate contact with the water which is necessary for efficient operation.) The “eye” may be cleaned with liquid detergent.

2.Improper installation of the transducer can alter the efficiency and accuracy of the entire system.

3.If your boat of transducer is out of the water for a period of time, it may take a short period of time for the transducer to become thoroughly “wetted” when returned to the water. Also, re- entry may cause turbulence, which will create air bubbles in the “eye” of the transducer. The bubbles will disappear in a short time or can be removed by rubbing the transducer “eye” with your fingers while the transducer is in the water.

4.If your instrument should fail to function, be sure to check all the electrical connections before removing the transducer or calling a serviceman.

5.Inspect your transducer cable and make sure that it has not been cut or damaged to the point where it will affect the performance of the transducer. A slight nick or cut, exposing the outer cable, can be repaired by wrapping with electrical tape. A transducer can be damaged if the inner cable and outer cable are allowed to make contact. Such a problem can sometimes be corrected by properly splicing the coaxial cable. This should only be attempted by a qualified service technician.

6.If your LCR is not working properly and you suspect the problem might be in your transducer, we would recommend you borrow a unit from a friend and try it on your boat. If the symptoms are the same, you can almost be certain that the problem is in the transducer.

INSTALLING THE LCR

The LCR should be mounted on a flat, solid surface for maximum stability. The low profile swivel mount has four holes drilled in the base. It is recommended that all four holes be used.

Position the swivel base and drill four ¼” diameter holes. Note: The LCR hole pattern Is the same as for all Humminbird flasher units. Use hardware provided to mount this base to the boat.

Next place the gimbal bracket on the swivel base and attach with four small machine screws, provided.

Place the LCR in the gimbal mount and make certain the rubber washers provided are placed between the unit and the gimbal bracket Important: Note which side of the gimbal faces forward. (Slots on gimbal bracket go towards rear). Also, rubber washer must be located between the unit and the gimbal bracket.

LCR 8000D, LCR 8000 specifications

The Humminbird LCR 8000 and LCR 8000D are advanced fish finders designed for avid anglers who seek precision and reliability on the water. These devices are known for their high-performance features that enhance the fishing experience, making it easier to locate fish and understand underwater structures.

One of the standout characteristics of the LCR 8000 series is its large display, which typically measures 8 inches. The screen is designed to offer exceptional clarity and visibility, even in bright sunlight. With a resolution of 640 x 480 pixels, users can expect sharp images and detailed sonar readings. The LCR 8000D version takes this a step further with additional features such as a split-screen display, allowing users to monitor multiple functions simultaneously.

These models integrate advanced sonar technology, including dual-beam sonar capabilities. The LCR 8000 and 8000D can operate on both narrow and wide beam frequencies, enabling anglers to cover more water and get a more comprehensive view of underwater environments. The fish symbol identification feature provides an intuitive way for users to discern between fish and other objects, enhancing their chances of a successful catch.

Another notable feature is the AutoZoom capability, which automatically adjusts the viewing area to focus on the depth range where fish are most likely to be present. This real-time information helps users make quick decisions about where to cast their lines.

Additionally, the LCR 8000D offers an integrated temperature sensor, providing real-time water temperature readings that can be crucial for understanding fish behavior. The ability to record sonar logs is another innovative aspect, allowing users to review their fishing trips and analyze data for future outings.

Both models boast rugged construction suitable for various weather conditions, ensuring durability on the water. The user-friendly interface and straightforward controls make it accessible for both seasoned professionals and recreational anglers alike.

In conclusion, the Humminbird LCR 8000 and LCR 8000D represent a significant advancement in fish finding technology, combining powerful sonar capabilities, user-friendly design, and robust construction. These devices are designed to elevate the fishing experience, enabling users to optimize their time on the water and increase their chances of success.
