5 This will help you m ake 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. Install the transducer and route the transducer cable to the sonar unit.[...]

6 Notes[...]

7 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 com es packaged with a one-piece stainless steel bracket for mounting it to the[...]

8 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. If the transd u c e r i[...]

9 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 combination of smooth water flow and protec- tion from bangs and bumps. Align transducer centerline with hull bottom. If [...]

10 transducer up or down. If you freq uently 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 th e 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 ob ject str[...]

11 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[...]

12 If the transducer's face isn't parallel with the ground, remove the transducer and ratchets from the br acket. Place the ratchets into the holes in the bracket with the lette r "B" aligned with the dot stamped in the bracket. Reassemble the transducer and bracket and place them against the transom. Again, check to see if you [...]

13 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 sh ould 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[...]

14 Route cable over bolt and through brac ket. 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 m ount- ing screws, sealing them with the sealant[...]

15 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. This can prevent the transducer from enter- ing the boat if it is knocke[...]

16 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. Route the transducer cable alon gside the trolling motor shaft. Use plastic ties (not included) to at[...]

17 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. NOTE: Periodically wash the transducer's face[...]

18 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 th rough solid fiberglass. A successful transducer installation can be made on hulls with flotation materials ([...]

19 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.[...]

20 3. Now move the transducer around to find the best location with the strongest possible bottom signal. If yo u find a spot with an acceptable bottom signal, mark the locati on and move on to step 4. If you can not get an acceptable botto m signal, try turning up the sensi- tivity by three or five keystrokes and then move the transducer around on[...]

21 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. The surface of the hull must be flat so the entire trans- ducer face is [...]

22 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 ha ve 20 minutes to complete the in- stallation before the epoxy becomes unworkable. Spread a thin layer of epoxy (about 1/16" or 1.5 mm thick) on the face of the transduc[...]

23 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. This will let you shut off power to the power cable when[...]

24 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 it. The power cable has two wires, red an d black. Red is the positive lead, black is negative or ground. Make su re to atta[...]
