8 chart. The sonar's microprocessor calculates the time lapse between the transmitted signal and echo return to determine the distance to the object. The whole process repeats itself several times each second. How to use this manual: typographical conventions Many instructions are listed as numbered steps.
9 Instructions = Menu Sequences Most functions you perform with the sonar unit are described as a se- quence of key strokes and selecting menu commands. We've written them in a condensed manner for quick and easy reading. For example, instructions for turning on the Fish ID feature would look like this: 1.
10 Notes.
11 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 drill- ing any holes in your vehicle or vessel! 1.
12 vent 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.
13 Selecting a Transducer Location 1. The location must be in the water at all times, at all operating speeds. 2. The transducer must be placed in a location that has a smooth flow of water at all times.
14 be displayed on the sonar's screen. Use caution when routing the trans- ducer cable around these wires. 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.
15 However, there are times when you may need to adjust the transducer slightly higher or lower. (The slots in the mounting brackets allow you to loosen the screws and slide the transducer up or down.
16 Lack of angle adjustment can be particularly troublesome on hulls that sit with the bow high when at rest or at slow trolling speeds. Third, a transducer CAN NOT shoot through wood and metal hulls. Those hulls require either a transom mount or a thru-hull installation.
17 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" position is correct for your hull. If the transducer's face isn't parallel with the ground, remove the transducer and ratchets from the bracket.
18 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.
19 5. Attaching transducer to transom. Remove the transducer from the bracket and re-assemble it with the cable passing through the bracket over the bolt as shown in the following figures. Route cable over bolt and through bracket. Side view shown at left and seen from above at right.
20 tra nsd uce r. If possible, route the transducer cable away from other wir- ing on the boat. 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.
21 Attach motor mounting bracket to 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. Posi- tion the transducer to aim straight down when the motor is in the wa- ter.
22 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.
23 Shoot-Thru-Hull Preparation Hulls With Floatation 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.
24 Testing Determines Best Location Ideally, the shoot-thru transducer should be installed as close to the transom as possible, close to the centerline. This will give you the best performance during high speed maneuvers. Shoot-thru-hull transducer locations for high speed or trolling speed operation.
25 Example of a second bottom signal. Unit is in 30 feet of water, with range set at 80 feet and sensitivity set at 87 percent. 2. Next, take the transducer out of the water and place it in the water in the sump of the boat, face down. (The transducer face is shown in the figure on the following page.
26 with the boat on plane and observe the bottom signal. You'll need to figure some way to prop the transducer into position while you make your test run. (A brick or two might be sufficient to hold it in place.) 5. When you're satisfied with a location, mark it and proceed with the installation.
27 WARNING: Use only the epoxy available from LEI. It has been for- mulated to work with these installation procedures. Other epoxy types may be too thin or may not cure to the right consistency for optimum transducer performance. 2. The epoxy consists of the epoxy itself and a hardener.
28 Speed/Temperature Sensors The FishEasy 320C can accept as many as two temperature sensors, which can be used to monitor the temperature of surface water, a live well or some other location. These units can accept an optional speed sensor for showing speed and distance traveled.

31 Sonar unit with external speed sensor. The temperature sensor is built into the transducer. Speed Sensor Installation If you wish to purchase an optional sensor for your unit, refer to the accessory ordering information inside the back cover of this manual.
32 water flow to the speed sensor. Make sure the sensor will remain in the water when the boat is on plane. Also make sure the location doesn't inter- fere with the boat's trailer. Typically, the sensor is mounted about one foot to the side of the transom's centerline.
33 If the base of the transom has a radius, fill the gap between the tran- som and the sensor with the caulking compound. This will help ensure a smooth water flow.
34 stalling an inline switch. This will let you shut off power to the power cable when the unit is not in use. When you are not using the unit, you should always shut off power to the power cable, es- pecially when the power cable is disconnected from the unit.
35 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. MOUNTING THE SONAR UNIT: In-Dash, Bracket or Portable You can install the sonar unit on the top of a dash with the supplied bracket.
36 Front view (left) and side view (right) showing dimensions of the FishEasy 320C when mounted on quick release bracket. After drilling the hole, pass the connectors up through the hole from und er the da sh. If you wish, you can fill in the hole around the cable with a good marine caulking compound.
37 FishEasy 320C quick release mounting bracket. Slots in the base allow routing the cable from beneath the mount. Attach the unit to the bracket by first connecting the power/transducer and accessory cables. Then, hold the sonar unit vertically and slide it onto the bracket from above.
38 Mount the sonar: slide the unit onto the bracket from above. Adjust viewing angle: use one hand to press and release the spring- loaded ratchets while you move the unit with the other hand. Portable Sonar Installation Like many Eagle products, the FishEasy 320C sonar is capable of port- able operation.
39 The power pack and portable transducers expand the uses for your so- nar. You can use your FishEasy 320C sonar unit on your boat or take it to the dock, on a float tube, on an ice fishing trip or use it as a second sonar in a friend's boat. The PPP-12 package includes the power pack, battery adapter and a port- able transducer.
40 PPP-12 Portable Power Pack with FishEasy 320C stowed for transport. Turn the sonar unit on. If it doesn't work, make sure the battery termi- nals are making good contact against the battery contacts. Also check the wiring connections on the battery adapter.
41 Portable Transducer Assembly Recommended tools for installation include a slotted screw driver and two adjustable wrenches. Assemble the transducer and bracket as shown in the following figure. Attach the transducer to the bracket with the supplied hardware.
42 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. Portable transducer installed on boat transom. NOTE: For optimum operation, the portable transducer should be adjusted so that it is parallel to the ground.
