1. Thru hull transducers install through a hole drilled in the hull of the boat Larger boats or boats with inboard motors create CX turbulence that make transom mounting ineffective Also hulls that are very thick or are double layered or made from materials such as wood or metal which do not conduct sonar signals make inside the hull mounting inadvisable Thru hull mounting may require the use of a fairing block to level the transducer with the waterline Also since special tools and knowledge may be required to perform this type of installation it is best to refer to a qualified marine technician INSTALLATION PREPARATION TRANSDUCER EXCHANGE TRANSDUCER EXCHANGE Other transducers are available as replacements for the standard transducer You may exchange your new and unassembled transducer for another type by returning it to the address listed in Customer Support Some transducers may have additional cost Refer to the Accessory catalog or call Customer Support for information BEGINNING INSTALLATION Now that you have determined the transducer mounting method you can begin installation of your new Humminbird fishfinder The installation guide included on the next few pages provides detailed step by step instructions for installation of the control head and transducer For transom mount transducer installations you will need the mounting template included with your manual In addition to the parts included you need the followi2. THE PRO FLASHER The Pro Flasher differs from LCD depthsounders in two important ways Operation of the unit is completely manual Adjustment of the sensitivity and noise reject controls and interpretation of the information displayed is entirely up to the user Also there is no history retained on screen Information displayed is in the form of instantaneous flashes of light on the dial targets beneath your boat will appear on screen for only as long as they are reflecting the sonar signal As with any sonar product the best way to learn to use the Pro Flasher is to operate ina familiar area and study the information presented on the display As you gain experience with the unit you will be able to quickly analyze the underwater situation and understand the conditions that lead to more productive fishing The Pro Flasher uses a super bright LED light source to indicate sonar returns Since the display is naturally light emitting it is ideal for use at night or in low light situations The rubber lens hood prevents washout in even the brightest sunlight As with all Humminbird products all moving parts are ruggedized for tough shock and vibration endurance and special components allow the Pro Flasher to operate at temperatures more extreme than you are likely to encounter Your Pro Flasher may be used on an existing Wide Eye Wide View or Wide Vision mounting base Once mounted it will automatically sense and use the 200 KHz 16 elemen

4. If the bottom is visible on screen with a digital depth readout the unit is working properly Ensure the boat is in water greater than 2 but less than the depth capability of the unit and the transducer is fully submerged Remember the sonar signal cannot pass through air If the unit is working properly gradually increase the boat speed to test high speed performance If the unit functions well at low speeds but begins to skip or miss the bottom at higher speeds the transducer requires adjustment Refer to the appropriate transducer installation section for more detail Note it is often necessary to make several incremental transducer adjustments before optimum high speed performance is achieved Important For Transom Mount transducer installations install the third mounting screw after the final transducer adjustments Humminbird e 3 Humminbird Lane e Eufaula Alabama 36027 TESTING THE INSTALLATION After installing your Pro Flasher and transducer you are ready to test the installation Testing should be performed on the water since that is the best way to confirm your transducer s performance With your boat in the water turn the Sensitivity OnOff control clockwise You should hear the disk start to spin and see an area of light at the 0 line on the dial and another at the number corresponding to the depth of the water Turning the Sensitivity control further clockwise increases the sensitivity of the unit so smaller return
5. at The transducer converts electrical energy from the transmitter into mechanical pulses or sound waves The transducer also receives the reflected sound waves and converts them back into electrical signals for display on the control head It should be installed in contact with the surface of the water in an area that has smooth waterflow usually on the transom of the boat There are several mounting options for the transducer Review the following section to determine the method that works for you and your boat INSTALLATION PREPARATION INSTALLATION OVERVIEW Determining How to Mount the Transducer Your Humminbird fishfinder includes a standard transducer This transducer can be mounted on the transom of the boat or bonded to the inside of a fiberglass hull boat The transom installation which is the most widely used places the transducer on the outside of the boat hull This technique produces the least signal loss and provides a way to adjust the transducer after installation The mounting hardware included is designed to protect both the boat and the transducer should the boat strike debris in the water or when trailering Transom Mounted Transducer As an alternative to transom mounting it is possible on many fiberglass hulled boats to glue the transducer on the inside of the boat hull Since fiberglass has similar sonar characteristics as water the sonar signal can pass through the boat hull with minimal loss The hull
