  • Page 6: How Sonar Works

    How Sonar Works Sonar has been around since the 1940s, so if you already know how it works, skip ahead to the next segment on the typographical conventions used in this manual. But, if you've never owned a sonar fish finder, this segment will tell you the underwater basics.
  • Page 7: How To Use This Manual: Typographical Conventions

    (Lowrance developed the world's first transistorized sportfishing sonar in 1957.) A sonar consists of a transmitter, transducer, receiver and dis- play. 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.
  • Page 8 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.
  • Page 9: Installation And Accessories

    Installation and Accessories Installation 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.
  • Page 10: 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 in the form of random lines or dots whenever the boat is moving.
  • Page 11 CAUTION: Clamp the trans- ducer cable to transom near the transducer. This will help prevent the transducer from entering the boat if it is knocked off at high speed. Good location Poor angle Good and poor transducer locations. How low should you go? For most situations, you should install your Skimmer transducer so that its centerline is level with the bottom of the boat hull.
  • Page 12: Shoot-Thru-Hull Vs. Transom Mounting

    Shoot-thru-hull vs. Transom Mounting Typically, shoot-thru-hull installations give excellent high speed opera- tion and good to excellent depth capability. There is no possibility of damage from floating objects. It can't be knocked off when docking or loading on the trailer. However, the shoot-thru-hull installation does have its drawbacks.
  • Page 13 holes in the bracket with the letter "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 can move the transducer so it's parallel with the ground. If you can, then go to step 3. If it doesn't, repeat step 2, but use a different alignment letter until you can place the transducer on the transom correctly.
  • Page 14 Transom Position transducer mount on transom and mark mounting holes. Side view shown at left and seen from above at right. 5. Attaching transducer to transom. Remove the transducer from the bracket and re-assemble it with the cable passing through the bracket over the bolt as shown in the following figures.
  • Page 15: Trolling Motor Bracket Installation

    6. Route the transducer cable through or over the transom to the sonar unit. Make sure to leave some slack in the cable at the transducer. If possible, route the transducer cable away from other wiring on the boat. Electrical noise from the engine's wiring, bilge pumps, VHF radio wires and cables, and aerators can be picked up by the sonar.

  • Page 17: Shoot-Thru-Hull Preparation And Installation

    To choose the proper location for thru-hull mounting, anchor the boat in 60 feet of water. Add a little water to the sump of the boat. Plug the trans- ducer into the sonar unit, turn it on, then hold the transducer over the side Inner hull...
  • Page 18 Next, take the transducer out of the water and place it in the water in the sump of the boat. Observe the sonar signal to see if there is a no- ticeable decrease in sensitivity. The second bottom signal may disap- pear and the bottom signal may decrease in intensity.
  • Page 19: Speed/Temperature Sensors

    Speed/Temperature Sensors The X67C can accept as many as two temperature sensors, which can be used to monitor the temperature of surface water, a live well or some other location. These units can accept an optional speed sensor for show- ing speed and distance traveled.

  • Page 22: Speed Sensor Installation

    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, screwdriver.
  • Page 23: Power Connections

    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".

Turn the sonar unit on. If it doesn't work, make sure the battery termi- nals are making good contact against the battery contacts.
  • Page 29: Portable Transducer Assembly

    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 37 You can customize how the Sonar Page pictures and other data are dis- played in many ways. We'll discuss all of those features and options in the Advanced Section, but to show you how easy the sonar unit is to op- erate, the following page contains a simplified, 10-step quick reference that will cover most fish finding situations.
  • Page 38: Basic Sonar Quick Reference

    The auto settings will track the bottom, displaying it in the lower por- tion of the screen. The full sonar chart will scroll from right to left, showing you what's under the boat as you cruise across the water.
  • Page 39: Sonar Operations

    As you can see from the quick reference on the previous page, basic operation is pretty easy, right out of the box. If you are a sonar novice, try operating the unit with the factory defaults until you get a feel for how it's working.
  • Page 40 You can tell the car to run faster, but when you let off the gas the cruise control automatically keeps you from running slower than the minimum speed setting. In the sonar unit, auto mode will let you increase sensitiv- ity to 100 percent, but the unit will limit your minimum setting. This pre- vents you from turning sensitivity down too low to allow automatic bot- tom tracking.
  • Page 41: Fish Symbols Vs. Full Sonar Chart

    Fish I.D. fish symbol feature. Here's why. 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.
