Dual-frequency transom installations Tools: two adjustable wrenches, dr ill, #20 (0.161") drill bit, flat-head screwdriver (for mounting screws[...]

5 Good and poor transducer locations. 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. A [...]

6 There are two extremes you should avoid. Never let the edge of the mounting bracket extend below the bottom of the hull. Never let the bottom – the face – of the tran sducer rise above the bottom of the hull. Shoot-thru-hull vs. Transom Mounting Typically, shoot-thru-hull installation s give excellent high speed opera- tion and good to excell[...]

7 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 lette[...]

8 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 "[...]

9 parallel with the ground. If you can, then go to step 3B. If it doesn't, repeat step 2B, but use a different alignment letter until you can place the transducer on the transom correctly. Assemble transducer and bracket. 3. Assembling the transducer. A. One-piece bracket: Once you determine the correct position for the ratchets, assemble the [...]

10 Mark the center of each slot for the mounting screw pilot holes. You will drill one hole in the center of each slot. Drill the holes. For the one-piece bracket, use the #29 bit (for the #10 screws). For the two-piece bracket, use the #20 bit (for the #12 screws). Position transducer mount on transom and mark mounting holes. Side view shown at le[...]

11 Both bracket types: Attach the tran sducer 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 groun[...]

12 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 ca using the noise. Don't allow the transducer bracket to go below the bottom of the hull! TROLLING MO[...]

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

14 transducer installation can be made on hulls with flotation materials (such as plywood, balsa wood or fo am) 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, finishi[...]

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 a[...]

16 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 wi th the hull, with a minimum amount of epoxy between the hull and tr ansducer. After the epoxy dries, route the cable to the sonar unit.

19 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. The following instructions describe how to install the speed sensor. Recommended tools for this job include: drill, 5/8"drill bit, 1/8" drill bit for pilot holes, screwdri[...]

20 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. 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 5/8&qu[...]

21 power buss. This will protect both the unit and the power cable in the event of a short. It uses a 3-amp fuse. CAUTION: Do not use this product withou t a 3-amp fuse wired into the power cable! Failure to use a 3-amp fuse will void your wa rranty. This unit has reverse polarity protection. No damage will occur if the power wires are reversed. Ho[...]

22 mounting positions. Installation inst ructions for the in-dash and swivel mounting kits are supplied with the adapter kits. Bracket Installation Mount the unit in any convenient loca tion, provided there is clearance when it’s tilted for the best viewin g angle. Holes in the bracket’s base allow wood screw or through-bolt mounting. Front vie[...]

23 be sure to leave enough slack in the cables to allow tilting or swiveling the unit. If you choose to fill in the ho le, be sure to position the cables against the rear edge of the hole as you apply the fill material. Before positioning the bracket, be sure to hold the cables against the rear edge of the hole. Then, slide the br acket over the ho[...]

24 For a secure portable mount, attach the unit to the portable power pack's gimbal bracket using the supplied gimbal knobs and washers as shown above. Installing the Batteries Release the latch on the front of the battery case. Open the compart- ment and install either an optional rechargeable battery or eight "D" cell batteries int[...]

25 Install batteries in power case battery adapter. In cold weather the efficiency of dr y cell batteries drops with the tem- perature. We find it a good idea to have the sonar unit good and warm along with the batteries before we leave home. If the batteries do lose a charge , you can sometimes restore them by placing them in a warm room or car in[...]

26 Portable transducer assembly: rear view (left) and side view (right.) Clean the chosen area of the hull be fore attaching the suction cup. Lo- cate the transducer on the hull as shown in the following figure. Don't allow the bracket to extend below the hull, because water pressure against it can cause the suction cup to come off at speed. M[...]

27 Operation KEYBOARD BASICS The unit sounds a tone when you press any key. This tells you the unit has accepted a command.

35 When you Zoom in manual Range mode, echoes are enlarged near the middle of the displayed range. For example, with a manual depth Range of 100 feet, your screen shows the water column from zero at the top of the screen to 50 feet in the middle to 100 feet at the bottom of the screen. Select 2X Zoom and the screen will show the water column from z[...]

36 You can change the sensitivity level whether you are in Auto Sensitiv- ity mode or Manual Sensitivity mo de. The adjustment method works the same in both modes, but it gi ves you slightly different results. Adjusting sensitivity in Auto Sensitiv ity Mode is similar to manually ad- justing a car's speed with the accelera tor pedal while crui[...]

FISH I.D.  The Fish I.D.  feature identifies targets th at meet certain conditions as fish. The microcomputer analyses all echoes and eliminates surface clutter, thermoclines a[...]

39 Fish I.D. is an easier way for a sonar novice to recognize a fishy signal return when he sees it. However, locating fish by symbol only has some limitations. Your sonar unit's microcomputer is so phisticated, but it can be fooled. It can't distinguish between fish an d other suspended objects such as trotlines, turtles, submerged float[...]

40 Fish ID menu and symbol with FishTrack on. The fish is 44 feet deep. FISHREVEAL  When displaying actual sonar returns, the FishReveal  feature helps show fish targets hidden by surface clutter, thermoclines, weed beds and other cover with 10 levels of gray tones. Normal operation (with FishReveal turned off) shows the weakest ech- oes as b[...]

41 There are two FishReveal modes: st andard and inverted. In standard mode, the weakest echoes are white and the strongest echoes are black. Echoes in between vary in gray in proportion to their signal strength. In Inverted FishReveal mode, the weakest echoes are black and the strongest echoes are white. Again, echoes in between vary in gray in pr[...]

42 If you are at anchor, ice fishing or fishing from a dock, experiment with a chart speed of 20 percent. If you are drifting slowly, try a chart speed of 40 percent. When you are stationary and a fish swims through the sonar signal cone, the image appears on the screen as a long line in- stead of a fish arch. Reducing the chart speed may result in[...]

43 ASP is an effective tool in combating noise. In sonar terms, noise is any undesired signal. It is caused by el ectrical and mechanical sources such as bilge pumps, engine ignition systems and wiring, air bubbles passing over the face of the transducer, even vibration from the engine. In all cases, noise can produce unwanted marks on the display.[...]

44 To turn Fish I.D. on, press MENU until the F ISH ID menu appears. Press UP ARROW to select O N , then press PWR . To turn off the fish alarm without turning off fish symbols, press MENU DOWN until F ISH A LARM appears. Press DOWN ARROW to select O FF , then press PWR to clear the menu. Repeat the above steps to turn the alarm back on, but press [...]

Press PWR to clear the screen. System Info screen. SIMULATOR This unit has a built-in simulator th at shows a simulated bottom signal with fish signals. This [...]

51 NOTE: If you turn on your unit before a ttaching a transducer, it may enter a demo mode. The words "demo mo de" flash on the bottom of the screen and a sonar chart plays much like the simulator. Unlike the simulator, the demo mode is for demonstration only, and will auto- matically stop as soon as you turn on the unit with a transducer[...]

52 High boat speed and slow ping speed (caused by the deeper bottom) can reduce the screen refresh rate. This in turn can reduce the amount of detail seen on the sonar chart. Try this command only if you are in deep water, traveling at high speed, and notice a reduction in detail on the sonar chart. When Limit Search is turned on, the digital sonar[...]

53 The default frequency is 200 kHz, whic h is best for use in shallow water (about 300 feet or less). This freque ncy is the best choice for about 80 percent of the fresh and salt water sport fishing applications. When you get into very deep salt water, 300 to 500 feet or deeper, the 50 kHz fre- quency is the best choice. The 200 kHz transducer wi[...]

The water may be deeper than the sonar's ability to find the bottom. If the sonar can't find the bottom si gnal while it's in the automatic mode, the digital sonar display will flash continuously. It may[...]

57 NOISE A major cause of sonar problems is electrical noise. This usually ap- pears on the sonar's display as random patterns of dots or lines. In se- vere cases, it can completely cover the screen with black dots, or cause the unit to operate erratically, or not at all. To eliminate or minimize the effects of electrical noise, first try to d[...]
