1 Section 1: Read Me First! How this manual can get you out on the water, fast! Welcome to the exciting world of digital sonar! We know you're anxious to begin finding fish, but we have a favor to ask. Before you grab your unit and begin installing it, please give us a moment or two to explain how our manual can help you get the best performan[...]

2 After you've gained some experience with your sonar, you'll want to check out Section 4, which discusses more advanced Sonar Options and Other Features . When you come to a sonar menu comma nd on the unit's screen, you can look it up in the manual by skimming over the table of contents, just flipping through Section 3 or scan ning [...]

3 Back-up memory: .......... Built-in memory stores sonar records for decades. Languages: ...................... 10; menu languages selectable by user. Sonar Frequency: ...................... 50/200 kHz for SeaFinder 480DF; 200 kHz for FishMark 480. Transducers: .................. A dual-frequency Skimmer  transducer with built-in temperature se[...]

4 Speed/distance log: ....... Optional (requires optional speed sensor). NOTICE! The storage temperature range for your unit is from -4 degrees to +167 degrees Fahrenheit (-20 degrees to +75 degrees Celsius). Extended storage in temperatures higher or lower than specified will damage the liquid crystal display in your unit. This type of damage is n[...]

5 menu command to use by finding the boldface command text. The following paragraphs explain how to interpret the text formatting for those commands and other instructions: Arrow Keys The arrow keys control a horizontal line depth cursor on the sonar screen. The arrow keys also help you move around the menus so you can execute different commands. T[...]

6 Translated into complete English, step 1 above would mean: "Start on the Sonar Page. Press the Menu key then repeatedly press (or press and hold) the down arrow key to scroll down the menu and select (highlight) the Sonar Features menu command. Then press the Enter key." Step 2 would mean: "Press the right arrow key (for dual-frequ[...]

7 Section 2: Installation & Accessories Preparations You can install the sonar system in some other order if you prefer, but we recommend this installation sequence: Caution: You should read over this entire installation section before drilling any holes in your vessel! 1. Determine the approximate location for the sonar unit, so you can plan h[...]

8 These are all "kick-up" mounting brac kets. They help prevent damage if the transducer strikes an object while the boat is moving. If the transducer does "kick-up," the bracket can easily be pushed back into place without tools. Read these instructions carefully before attempting the installation. Determine which of the mounti[...]

9 then the chosen location must be in the water at all times. If the transducer is not placed in a smooth flow of water, interference caused by bubbles and turbulence will show on the sonar's display in the form of random lines or dots whenever the boat is moving. NOTE: Some aluminum boats with strakes or ribs on the outside of the hull create[...]

10 How low should you go? For most situations, you should install your Skimmer transducer so that its centerline is level with the bottom of the boat hull. This will usually give you the best combination of smooth water flow and protection from bangs and bumps. Align transducer centerline with hull bottom. However, there are times when you may need[...]

11 However, the shoot-thru-hull installation does have its drawbacks. First, some loss of sensitivity does occur, even on the best hulls. This varies from hull to hull, even from different installations on the same hull. This is caused by differences in hull lay-up and construction. Second, the transducer angle cannot be adjusted for the best fish [...]

12 B. Two-piece bracket: Locate the four plastic ratchets in the transducer's hardware package. Press two ratchets into the sides of the plastic bracket and two on either side of the transducer as shown in the following illustrations. Notice there ar e letters molded into each ratchet. Place the ratchets into the bracket with the letter "[...]

13 2. Aligning the transducer on the transom. A. One-piece bracket: Slide the transducer between the two ratchets. Temporarily slide the bolt though the transducer assembly and hold it against the transom. Looking at the transducer from the side, check to see if it will adjust so that its face is parallel to the ground. If it does, then the "A[...]

14 bracket holes with the letter "B" aligned with the bracket alignment mark. Place them on the transducer aligned with the 12 o'clock position on the transducer stem. Reassemble the transducer and bracket and place them against the transom. Again, check to see if you can move the transducer so it's parallel with the ground. If [...]

15 B. Two-piece bracket: Once you determine the correct position for the ratchets, assemble the transducer as shown in the figure in step 2B. Don't tighten the lock nut at this time. 4. Drilling mounting holes. Hold the transducer and bracket assembly against the transom. The transducer should be roughly parallel to the ground. The transducer&[...]

16 Both bracket types: Attach the transducer to the transom. Slide the transducer up or down until it's aligned properly with the bottom of the hull as shown in the preceding and following figures. Tighten the bracket's mounting screws, sealing th em with the caulking compound. Adjust the transducer so that it's parallel to the groun[...]

17 Caution: If you drill a hole in the transom for the cable, make sure it is located above the waterline. After installation, be sure to seal the hole with the same marine grade above- or below-waterline sealant used for the mounting screws. 7. Make a test run to determine the results. If the bottom is lost at high speed, or if noise appears on th[...]

18 Transducer mounted on trolling motor, side view. TRANSDUCER ORIENTATION AND FISH ARCHES If you do not get good fish arches on your display, it could be because the transducer is not parallel with the ground when the boat is at rest in the water or at slow trolling speeds. Transducer angles and their effects on fish arches. Transducer aimed too f[...]

19 If the arch slopes up – but not back down – then the front of the transducer is too high and needs to be lowered. If only the back half of the arch is printed, then the nose of the transducer is angled too far down and needs to be raised. NOTE: Periodically wash the transducer's face with soap and water to remove any oil film. Oil and d[...]

20 WARNING: Do not remove any material from your inner hull unless you know the hull's composition. Careless grinding or cutting on your hull can result in damage that could sink your boat. Contact your boat dealer or manufacturer to confirm your hull specifications. To choose the proper location for th ru-hull mounting, anchor the boat in 60 [...]

21 100 grit sandpaper. The surface of the hull must be flat so the entire transducer face is in contact with the hull prior to bonding. Epoxy transducer to hull. 2. Follow the instructions on the epoxy package and mix it thoroughly. Do not mix it too fast, because it will cause bubbles to form in the epoxy. Apply a small amount on the face of the t[...]

22 If a second temp sensor is used, it must be the model TS-2U. This model has a fixed electronic "address" which designates it as the second of two temp sensors. Dual temperatures are only displayed on the Full Chart page. The Large Digital page will only display the primary temperature sensor. See the following wiring diagram for temper[...]

23 Optional Speed Sensor Installation All the units in this series can display speed and distance traveled, but only the SeaFinder 480DF comes packed with a speed sensor. If you wish to purchase an optional additional sensor for your unit, refer to the accessory ordering information inside the back cover of this manual. The following instructions d[...]

24 Stern view showing good location for mounting sensor on transom. If the base of the transom has a radius, fill the gap between the transom and the sensor with the caulking compound. This will help ensure a smooth water flow. Speed sensor mounting configuration: side view (left) and rear view (right.) Route the sensor's cable through or over[...]

25 attach the power cable directly to the battery. You can attach the power cable to an accessory or power buss, however you may have problems with electrical interference. Therefore, it's safer to go ahead and attach the power cable directly to the battery. CAUTION: When using the unit in a salt water environment, we strongly recommend that y[...]

26 Power connections for the sonar unit. CAUTION: Do not use this product without a 3-amp fuse wired into the power cable! Failure to use a 3-amp fuse will void your warranty. This unit has reverse polarity protection. No damage will occur if the power wires are reversed. However, the unit will not work until the wires are attached correctly. An op[...]

27 If you use the supplied bracket, you may be interested in the optional R-A-M  bracket mounting system. This converts the unit's gimbal bracket to a swivel mount, which can be used on the dash or overhead mounting positions. Installation instructions are supplied with the R-A-M mounting kits. Bracket Installation Mount the unit in any con[...]

28 After drilling the hole, pass the transducer connector up through the hole from under the dash. Pass the power cable's bare-wire end down though the hole from the top. If you wish, you can fill in the hole around the cables with a good marine caulking compound. (Some marine dealers stock cable hole covers to conceal the opening.) No matter [...]

NOTE: Water conditions vary greatly, an d that affects sonar performance. Under certain conditions, FishRevea l will show you more fish than normal grayscale mode, but the r[...]

58 all sonar units typically read deeper in fresh water than in salt water.) There is a common exception to these rules of thumb. Some fishermen on freshwater lakes (or the ocean) using downriggers like to see them on the sonar. In many of those cases, you'll see a 50 kHz transducer frequency in use because the wider cone angle lets them watch[...]
