Transducers: .................. A dual-fr equency Skimmer  transducer with built-in temperature sensor is packed with the SeaFinder 320DF. It has 35 ° /12 ° cone angles. A [...]

4 NOTICE! The storage temperature range for your unit is from -4 degrees to +167 degrees Fahrenheit (-20 degrees to +75 degrees Celsius). Extended stor- age in temperatures higher or lower than specified will damage the liq- uid crystal display in your unit. This type of damage is not covered by the warranty. For more information, contact the facto[...]

5 lowing 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. They are represented by symbols like these, which denote the down [...]

Next, press the Enter key, then press the Exit key twice."[...]

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 locati on for the sonar unit, so you can pla[...]

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 trans- ducer does "kick-up," the bracket ca n easily be pushed back into place without tools. Read these instructions carefully before attempting the installation. Determine which of the mou[...]

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 in stall your Skimmer transducer so that its centerline is level with th e bottom of the boat hull. This will usually give you the best combinat ion of smooth water flow and protec- tion from bangs and bumps. Align transducer centerline with hull bottom. However, there are times when you may[...]

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 differenc es 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 trans- ducer's hardware package. Press two ra tchets into the sides of the plas- tic bracket and two on either side of the transducer as shown in the f o l- lowing illustrations. Notice there ar e letters molded into each ratchet. Place the ratchets into the bracket with the lett[...]

13 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. Lookin g 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 &quo[...]

14 bracket holes with the letter "B" aligned with the bracket alignment mark. Place them on the transducer aligned with the 12 o'clock posi- tion 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. I[...]

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 trans- duce[...]

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 them with the caulking compound. Adjust the transducer so that it's parallel to the ground[...]

17 Caution: If you drill a hole in the transom fo r the cable, make sure it is lo- cated above the waterline. After installation, be sure to seal the hole with the same marine grade above- or below-waterline seal- ant 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 [...]

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 th e 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 [...]

19 If the arch slopes up – but not back down – then the front of the trans- ducer is too high and needs to be lo wered. 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 re- move any oil film. Oil [...]

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 th e epoxy package and mix it thoroughly. Do not mix it too fast, because it will cause bubbles to form in the ep- oxy. Apply a small amount on the face of th[...]

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 tem- perature sensor. See the following wiring diagram for temp[...]

23 Optional Speed Sensor Installation All the units in this series can disp lay speed and distance traveled, but only the SeaFinder 320DF comes pack ed with a speed sensor. If you wish to purchase an optional additi onal sensor for your unit, refer to the accessory ordering information in side the back cover of this man- ual. The following instruct[...]

24 If the base of the transom has a ra dius, fill the gap between the tran- som and the sensor with the caulki ng 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 the transom to the sonar unit. If you need to drill a hole i[...]

25 the unit is not in use. When the unit is turned off but still connected to a power supply, electrolysis can occur in the power cable plug. This may result in corrosion of the plug body along with the electri- cal contacts in the cable and the unit's power socket. In saltwater environments we recommend you connect the power cable to the auxi[...]
