  • Page 10: How Sonar Works

    Sonar has been around since the 1940s, so if you already know how it works, skip ahead to the next segment on the typographical conventions used in this manual. But, if you've never owned a sonar fish finder, this segment will tell you the under water basics.

  • Page 13: Section 2: Installation & Accessories

    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 how and where to route the cables for the transducer and power.
  • Page 14: Recommended Tools And Supplies

    These are all "kick-up" mounting brackets. 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 mounting positions is right for your boat.
  • Page 15 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 large amounts of turbulence at high speed.
  • Page 16: How Low Should You Go

    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.
  • Page 17: Transom Transducer Assembly And Mounting

    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 arches.
  • Page 18 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 are letters molded into each ratchet. Place the ratchets into the bracket with the letter "A"...
  • Page 19 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.
  • Page 20 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.
  • Page 21 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.
  • Page 22 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 them with the caulking compound. Adjust the transducer so that it's parallel to the ground and tighten the nut until it touches the outer washer, then add 1/4 turn.
  • Page 23: Trolling Motor Bracket Installation (Single-Frequency Only)

    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.
  • Page 24: Transducer Orientation And Fish Arches

    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.
  • Page 25: Shoot-Thru-Hull Preparation And Installation

    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.
  • Page 26 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 manufacturer to confirm your hull specifications. To choose the proper location for thru-hull mounting, anchor the boat in 60 feet of water.
  • Page 27: Speed/Temperature Sensors

    This unit is packed with a transducer containing a built-in temp sensor. The SeaFinder package also includes a speed sensor. If you have a FishMark 480 and want a speed sensor or additional temp sensor, see the Accessory Ordering Information in the back of this manual.
  • Page 28 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.
  • Page 29 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.
  • Page 30: Power Connections

    Good location 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. Transom Speed sensor mounting configuration: side view (left) and rear view (right.)
  • Page 31 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 saltwater environment, we strongly recommend that you shut off the power supply to the power cable...
  • Page 32: Mounting The Unit: Bracket, In-Dash Or Portable

    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 optional 8-foot, CA-4 external power cable with a cigarette lighter adapter is available from Eagle. Sonar unit rear view Power/trans-...
  • Page 33 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.
  • Page 34 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.
  • Page 35 Portable Installation Like many Eagle products, this sonar unit is capable of portable operation by using the optional PPP-13 portable power pack. The power pack and an optional portable transducer expand the uses for your sonar unit.
  • Page 36: Face Cover

    The PPP-13 Portable Power Pack can be used with eight "D" cell alkaline batteries or an optional sealed, rechargeable battery. For set- up directions, refer to the pack's instruction sheet, part 988-0147-601. "D" cell battery Install batteries in power pack battery adapter.

  • Page 39: Menus

    Menus Your sonar unit will work fine right out of the box with the factory default settings. You only need to learn a few basic functions to enhance your viewing. We'll discuss them briefly here, then talk about them and all the other commands in more detail in the next section, which begins on page 45.
  • Page 40 Main Menu Commands There are four "basic" Main Menu commands that you'll really want to read more about. They are: • Screen command: changes the contrast or brightness of the display screen. Use this command to adjust how the screen looks under various lighting conditions.
  • Page 41: Sonar Menu

    • Reset Options command: returns all options and auto functions to their original factory settings. It's a great safety net while you're learning and experimenting with various settings. • Set Language command: your unit has menus in 10 different languages. This command switches from one language to another. •...

This is a "cross- section" view of the water column beneath the boat. The chart moves across the screen, displaying sonar signal echoes that represent fish, structure and the bottom.
  • Page 44 Sonar chart display options (from left) split zoom (all models) and split frequency (SeaFinder 320DF only). Digital data sonar chart display option. You can customize how the Sonar Page pictures and other data are displayed in many ways. We'll discuss all of those features and options in Section 4, but to show you how easy the sonar unit is to operate, see the following 10-step quick reference that will cover most fish finding situations.
  • Page 45: Basic Sonar Quick Reference

    Basic Sonar Quick Reference 1. Mount the transducer and unit. Connect the unit to electric power and the transducer. 2. Launch your boat. 3. To turn on the unit, press and release 4. Head for your fishing grounds. Your unit automatically displays digital depth and surface water temperature in the corner of the screen.
  • Page 46: Sonar Operations

    9. If you are drifting at a very low speed or anchored, you are not moving fast enough for a fish to return the tell-tale fish arch signal. As you drift over a fish, or as a fish swims through the transducer's signal cone, the fish echo will appear as a straight line suspended between the surface and the bottom.
  • Page 47 Adjusting sensitivity in Manual Sensitivity Mode is similar to driving a car without cruise control — you have complete manual control of the car's speed. In the sonar unit, manual mode allows you to set sensitivity at 100 percent (maximum) or zero percent (minimum.) Depending on water conditions, the bottom signal may completely disappear from the screen when you reduce sensitivity to about 50 percent or less!
  • Page 48 To adjust sensitivity: 1. Press MENU 2. The Sensitivity Control Bar appears. Press ↓ to decrease sensitivity; press ↑ to increase sensitivity. When it's set at the desired level, press . (When you reach the maximum or minimum limit, a tone sounds.) EXIT At left, Sonar Menu with Sensitivity command selected.
  • Page 49: Fish Symbols Vs. Full Sonar Chart

    Fish Symbols vs. Full Sonar Chart You may have noticed in the quick reference that we used fish arches in full sonar chart mode for our example, and not the popular Fish I.D. fish symbol feature. Here's why. Fish I.D. is an easier way for a sonar novice to recognize a fishy signal return when he sees it.
  • Page 50 Aside from being just plain fun, this program can help you learn both basic and advanced operations without burning boat fuel! Eagle is one of the first sonar manufacturers to provide this type of training tool for customers.

FasTrack This feature automatically converts all echoes to short horizontal lines on the display's far right side. The graph on the rest of the screen continues to operate normally.
  • Page 59 There are several fish symbol sizes. These are used to designate the relative size between targets. In other words, Fish I.D. displays a small fish symbol when it thinks a target is a small fish, a medium fish symbol on a larger target and so on. The sonar's microcomputer is sophisticated, but it can be fooled.

    Fish visible Fish arch Sonar chart in regular grayscale mode, left, and in FishReveal mode, right. Notice how shallow fish formerly hidden in the surface clutter become visible in FishReveal mode. NOTE: Water conditions vary greatly, and that affects sonar performance. Under certain conditions, FishReveal will show you more fish than normal grayscale mode, but the reverse will be true in other circumstances.
  • Page 64: Grayline

    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 the bait.

It may save you the trouble of returning your unit for repair. For contact information, refer to the last page, just inside the back cover of this manual.
  • Page 86 Weak bottom echo, digital readings erratic, or no fish signals: 1. Make certain the transducer is pointing straight down. Clean the face of the transducer. Oil, dirt and fuel can cause a film to form on the transducer, reducing its effectiveness. If the transducer is mounted inside the hull, be sure it is shooting through only one layer of fiberglass and that it is securely bonded to the hull.
  • Page 87 spark plugs or routing the sonar unit's power and transducer cables away from other electrical wiring on the boat. No fish arches when the Fish I.D. feature is off: 1. Make certain the transducer is pointing straight down. This is the most common problem if a partial arch is displayed.
  • Page 88 no noise is present, turn the pump off, then turn on the VHF radio and transmit. Keep doing this until all electrical equipment has been turned on, their effect on the sonar display noted, then turned off. If you find noise interference from an electrical instrument, trolling motor, pump, or radio, try to isolate the problem.
