  • Page 21: Preparations, Transducer Installation

    Section 2: Installation Preparations You can install the sonar and GPS systems 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.

  • Page 22: Recommended Tools And Supplies, Transom Installation, Trolling Motor Installations, Shoot-through Hull Installations

    Determine which of the installation methods is right for your boat. Remember, the transducer location and 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 5/8"...

  • Page 23: Selecting A Transducer Location

    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 as random lines or dots when the boat is moving. NOTE: Some aluminum boats with strakes or ribs on the outside of the hull create large amounts of turbulence at high speed.

  • Page 24: How Low Should You Go

    5. If possible, route the transducer cable away from other wiring on the boat. Electrical noise from engine wiring, bilge pumps and aerators can be displayed on the sonar's screen. Use caution when routing the transducer cable around these wires.

  • Page 25: Shoot-thru-hull Vs. Transom Mounting

    Shoot-thru-hull vs. Transom Mounting In a shoot-thru-hull installation, the transducer is bonded to the inside of the hull with epoxy. The sonar "ping" signal actually passes through the hull and into the water. This differs from a bolt-thru-hull installa- tion (often called "thru-hull"). In that case, a hole is cut in the hull and a specially designed transducer is mounted through the hull with a threaded shaft and nut.

  • Page 26

    This is caused by differences in hull lay-up and construction. Second, the transducer angle cannot be adjusted for the best fish arches on your sonar display. (This is not an issue for flasher-style sonars.) Lack of angle adjustment can be particularly troublesome on hulls that sit with the bow high when at rest or at slow trolling speeds.

    Align plastic ratchets in bracket. 2. Aligning the transducer on the transom. Slide the transducer between the two ratchets. 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 to the ground.

    Transducer aimed too far back Full fish arch 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.

  • Page 34: 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. A successful 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.

  • Page 35: Testing Determines Best Location

    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. Adjust the sensitivity and range controls until a second bottom echo is seen on the display.

    Second bottom 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.

  • Page 37: Shoot-thru-hull Installation

    4. Most people can get good results by following steps 1 through 3, so this step is optional. If you want to make an extra effort to be absolutely sure that your selected location will work under all conditions, make a test run with the boat on plane and observe the bottom signal.

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 perform- ance.

  • Page 39: Power And Cable Connections

    Leave the weight in place for a minimum of three hours. Allow the epoxy to cure for 24 hours before moving the boat. 5. After the epoxy has cured, route the cable to the sonar unit and it's ready to use.

  • Page 41: Mounting The Sonar Unit: In-dash Or Bracket

    Mounting the Sonar Unit: In-Dash or Bracket You can install the sonar unit on the top of a dash with the supplied bracket. It can also be installed in the dash with an optional FM-6 dash-mounting kit.

  • Page 42: Bracket Installation

    (See the following drawings, which show the dimensions of a mounted Cuda 350 sonar unit.) Holes in the bracket’s base allow wood screw or through-bolt mounting. You may need to place a piece of plywood on the back side of thin pan- els to reinforce the panel and secure the mounting hardware.

  • Page 46: Portable Sonar Installation, Installing The Batteries

    Portable Sonar Installation Like many Eagle products, the Cuda 350 sonar is capable of portable operation. It uses the optional PPP-12 portable power pack. The power pack and portable transducers expand the uses for your so- nar. You can use your Cuda 350 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 so- nar in a friend's boat.

    In cold weather the efficiency of dry 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.

  • Page 48: Portable Transducer Assembly

    If the batteries do lose a charge, you can sometimes restore them by placing them in a warm room or car interior. A better way is to replace them with batteries that have been kept warm. WARNING: Never heat the batteries over an open flame or direct hot air onto them.

  • Page 61: To Adjust Sensitivity

    Adjusting sensitivity in Manual Sensitivity Mode is similar to driving a car without cruise control — you have complete control of the car's speed. In the sonar unit, manual mode allows you to set sensitivity at to the maximum or minimum settings. Depending on water conditions, the bottom signal may completely disappear from the screen when you reduce sensitivity to about 50 percent or less.

  • Page 62

    Tip: While you are experimenting and learning, it is possible to scram- ble the settings so the sonar picture disappears from the screen. If that happens, remember it is easy to switch back to full automatic operation by restoring the factory default settings.
