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 If you're having difficulty with your sonar, you can find an answer to the most common problems in Section 5, Sonar Troubleshooting . Finally, in Section 6, we offer Supplemental Material , including a list of warranty and customer service information. Now, if you're into the fine details, glance over the next segment on specifications [...]

In simple terms, here's how it finds the bottom, or the fish: The transmitter emits an electrical impulse, which the transducer con- verts into a sound wave and sends into the water. (The sound frequency can't be heard by humans or fish.) The sound wa[...]

5 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. From the Sonar Page, press MENU |[...]

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 drill- ing any holes in your vessel! 1. Determine the approximate location for the sonar unit, so you can plan[...]

8 extreme care if mounting the transducer inside the hull, because once it is epoxied into position, the transducer usually cannot be removed. Remember, the transducer installation is the most critical part of a sonar installation. Recommended Tools and supplies If you prefer the option of routing the cable through the transom, you will need a 1&qu[...]

9 3. If the transducer is mounted on the transom, make sure it doesn't interfere with the trailer or hauling of the boat. Also, don't mount it closer than approximately one foot from the engine's lower unit. This will prevent cavitation (bubble) interference with propeller operation. 4. If possible, route the transducer cable away fr[...]

10 quently lose bottom signal lock while running at high speed, the trans- ducer 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. If you wish, you may move th[...]

11 Align plastic ratchets in bracket. B. Two-piece bracket: Locate the four plastic ratchets in the trans- ducer's hardware package. Press two ratchets into the sides of the plas- tic bracket and two on either side of the transducer as shown in the fol- lowing illustrations. Notice there are letters molded into each ratchet. Place the ratchets[...]

12 Add ratchets to bracket and transducer. 2. Aligning the transducer on the transom. A. One-piece bracket: Slide the transducer between the two ratch- ets. 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 t[...]

13 B. Two-piece bracket: Assemble the transducer and bracket as shown in the following figure. Temporarily slide the bolt though the transducer assembly but don't tighten the nut at this time. Hold the assembled transducer and bracket against the transom. Looking at the transducer from the side, check to see if it will adjust so that its face [...]

14 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 trans- duce[...]

15 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[...]

16 7. Make a test run to determine the results. If the bottom is lost at high speed, or if noise appears on the display, try sliding the trans- ducer bracket down. This puts the transducer deeper into the water, hopefully below the turbulence causing the noise. Don't allow the transducer bracket to go below the bottom of the hull! TROLLING MOT[...]

17 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. If the arch slopes up – but not back down – then the front of the t[...]

18 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. Epoxy the transducer to a solid portion of the hull. For example, some (but not all) manufacturers use a layer of fiberglass, then a core of balsa wood, finishin[...]

19 cation that shot through the hull the best and follow the instructions on the following pages for a shoot-thru-hull mounting. Shoot-thru-hull transducer locations for high speed or trolling speed operation. 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 an[...]

20 Place the transducer into the epoxy, twisting and turning it to force any air bubbles out from under the transducer face. The face of the transducer should be parallel with the hull, with a minimum amount of epoxy between the hull and transducer. After the epoxy dries, route the cable to the sonar unit. Speed/Temperature Sensors This unit accept[...]

22 Optional Speed Sensor Installation All the units in this series can display speed and distance traveled, but only the X126DF and X136DF come 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 man- ual. The following instruction[...]

23 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. Route the sensor's cable through or over the transom to the sonar unit. If you need to drill a hole in the transom to pass the connector through, the required hole size is 7/8"[...]

24 lead, black is negative or ground. Make sure to attach the in-line fuse holder to the red lead as close to the power source as possible. For example, if you have to extend the power cable to the battery or power buss, attach one end of the fuse holder directly to the battery or power buss. This will protect both the unit and the power cable in t[...]

25 Sonar unit cable connections. Mounting the Unit: Bracket, In-Dash or Portable You can install the sonar unit on the top of a dash with the supplied gimbal bracket. It can also be installed in the dash or mounted on a portable power supply. If you use the supplied bracket, you may be interested in the optional R-A-M  bracket mounting system. T[...]

26 Optional R-A-M mounting system. Bracket Installation Mount the unit in any convenient location, provided there is clearance behind the unit when it's tilted for the best viewing angle. You should also make sure there is enough room behind the unit to attach the power and transducer cables. (A drawing on the next page shows the dimensions of[...]
