– right out of the box. All you have to do is press the on ( To get started with your Eagle sonar, first read the installation section. It contains instructions for mounting the sonar unit, the transducer and any optional accessories, such as a speed sensor.
Sonar has been around since the 1940s, so if you already know how it works, skip ahead to the next segment. But, if you have never owned a sonar fish finder, this segment will explain the under water basics. Sonar is an abbreviation for SOund NAvigation and Ranging, a tech- nology developed during World War II for tracking enemy submarines.
Dual Search & Dual Frequency The FishEasy 250 DS is packed with a Dual Search Skimmer Trans- ducer that can transmit at 83 kHz and 200 kHz. The SeaFinder 250 DF has a dual frequency transducer that transmits at 50kHz and 200kHz.

This will help you make sure you have enough cable length for the de- sired configuration. 2. Determine the approximate location for the transducer and its cable route. 3. Determine the location of your battery or other power connection, along with the power cable route. 4.
Section 2: Installation & Accessories These instructions will help you install your Skimmer transducer on a transom, on a trolling motor or inside a hull. Please read all instruc- tions before proceeding with any installation. Your Skimmer transducer typically comes packaged with a one-piece stainless steel bracket for mounting it to the transom of your boat.
Shoot-through hull installations Tools: these will vary depending on your hull's composition. Consult your boat dealer or manufacturer. Supplies: 100 grit sandpaper, good quality epoxy adhesive. Selecting a Transducer Location 1. The transducer must be placed in a location that has a smooth flow of water at all times.
CAUTION: Clamp the trans- ducer cable to transom near the transducer. This will help prevent the transducer from entering the boat if it is knocked off at high speed. Good location Poor angle Good and poor transducer locations. 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.
transducer up or down. If you frequently lose bottom signal lock while running at high speed, the transducer may be coming out of the water as you cross waves or wakes. Move the transducer a little lower to help prevent this. If you cruise or fish around lots of structure and cover, your transducer may be frequently kicking up from object strikes.
Third, a transducer CAN NOT shoot through wood and metal hulls. Those hulls require either a transom mount or a thru-hull installation. Fourth, if your Skimmer transducer has a built in temp sensor, it will only show the temperature of the bilge, not the water surface temp. Follow the testing procedures listed in the shoot-thru-hull installation section at the end of this instruction booklet to determine if you can satisfactorily shoot through the hull.

If the transducer's face isn't parallel with the ground, remove the transducer and ratchets from the bracket. Place the ratchets into the holes in the bracket with the letter "B" aligned with the dot stamped in the bracket. Reassemble the transducer and bracket and place them against the transom.
Page 17
Assemble transducer and bracket. 4. Drilling mounting holes. Hold the transducer and bracket assembly against the transom. The transducer should be roughly parallel to the ground. The transducer's centerline should be in line with the bottom of the hull. Don't let the bracket extend below the hull! Mark the center of each slot for the mounting screw pilot holes.

Route cable over bolt and through bracket. Side view (left) and shown from above (right). 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 mount- ing screws, sealing them with the sealant compound.
Electrical noise from the engine's wiring, bilge pumps, VHF radio wires and cables, and aerators can be picked up by the sonar. Use caution when routing the transducer cable around these wires. WARNING: Clamp the transducer cable to the transom close to the transducer.
2. Slide the adjustable strap supplied with the TMB-S through the slot in the transducer bracket and wrap it around the trolling motor. Po- sition the transducer to aim straight down when the motor is in the water. Tighten the strap securely. 3.

Transducer aimed too far back Full fish arch Transducer angles and their effects on fish arches. If the arch slopes up – but not back down – then the front of the trans- ducer 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.
Shoot-Thru-Hull Preparation Hulls With Flotation Materials The transducer installation inside a fiberglass hull must be in an area that does not have air bubbles in the resin or separated fiberglass lay- ers. The sonar signal must pass through solid fiberglass. A successful transducer installation can be made on hulls with flotation materials (such as plywood, balsa wood or foam) between layers of fiberglass if the material is removed from the chosen area.
Page 23
To choose the proper location for shoot-thru-hull mounting, follow these testing procedures. You may need a helper to complete these steps. 1. Anchor the boat in about 30 feet of water. Add a little water to the sump of the boat. Plug the transducer into the sonar unit, turn it on, then hold the transducer over the side of the boat in the water.
Page 24
3. Now move the transducer around to find the best location with the strongest possible bottom signal. If you find a spot with an acceptable bottom signal, mark the location and move on to step 4. If you can not get an acceptable bottom signal, try turning up the sensi- tivity by three or five keystrokes and then move the transducer around once more.
Shoot-thru-hull Installation 1. Make sure the area is clean, dry and free of oil or grease, then sand both the inside surface of the hull and the face of the transducer with 100 grit sandpaper. The sanded hull area should be about 1-1/2 times the diameter of the transducer.
Thoroughly stir the two compounds together until the mixture has a uniform color and consistency. Do not mix too fast or bubbles will form in the epoxy. After mixing, you have 20 minutes to complete the in- stallation before the epoxy becomes unworkable. Spread a thin layer of epoxy (about 1/16"...

In saltwater environments we recommend you connect the power cable to the auxiliary power switch included in most boat designs. If that results in electrical interference, or if such a switch is not available, we recommend connecting direct to the battery and in- stalling an inline switch.
If possible, keep the power cable away from other boat wiring, espe- cially the engine's wires. This will provide the best isolation from elec- trical noise. If the cable is not long enough, splice #18 gauge wire onto The power cable has two wires, red and black. Red is the positive lead, black is negative or ground.

Screw the suction cup onto the bracket using the supplied screw and flat washer. Tie the nylon cord through the hole in the top of the bracket. When using this transducer, tie the other end of the nylon cord to the boat. This will help prevent the loss of the transducer if it comes off the boat.
Page 34
Moisten the cup, then press it onto the hull as firmly as possible. Tie the nylon cord to the boat and route the transducer cable to the sonar unit. Your portable sonar is now ready for use. NOTE: For optimum operation, the portable transducer should be adjusted so that it is parallel to the ground.

FasTrack gives you a rapid update of conditions directly under the boat, making it useful for ice fishing or when fishing at anchor. When the boat is not moving, fish signals are long, drawn out lines on a nor- mal display. FasTrack converts the graph to a vertical bar graph that makes a useful addition to fishing at a stationary location.
Zoom The zoom feature enlarges all images on the screen by doubling (2X) or quadrupling (4X) the size of the echoes. When you activate the zoom command, the screen will be split in half with the zoomed area dis- played on the left. The normal view will be shown on the right side of the screen.

Your sonar unit's microcomputer is sophisticated, but it can be fooled. It can not distinguish between fish and other suspended objects such as trotlines, turtles, submerged floats, air bubbles, etc. Individual tree limbs extending outward from a group of limbs are the hardest objects for the Fish I.D.
Then, you can turn on Fish I.D. and the audible fish alarm. When that lunker swims under your boat, you will hear it! Fish I.D. can also be useful when you want to screen out some of the so- nar detail gathered by your unit. For example, it can help cut through the clutter of suspended bubbles caused by wave action or boat wakes.
Alarms Your sonar unit has four alarms: fish, shallow, deep and battery. NOTE: If one of the alarms goes off, press remain silent until it is triggered again. Fish Alarm The Fish Alarm sounds a tone when a fish symbol appears on the screen.

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 in- side the hull, be sure it is shooting through only one layer of fiberglass and that it is securely bonded to the hull.
Page 65
Try using resistor 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.

If 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.
