  • Page 3: Introduction

    INTRODUCTION The X-75 and X-85 are the latest members of the Lowrance family that combines a high performance sonar with a wide, high definition screen. Using menu features and “soft-key” operation, these units are also easy to use. The wide screen shows the underwater world with high resolution and detail.

  • Page 8: Connectors

    (NOT INCLUDED) CONNECTORS The diagram above shows the three connectors on the back of the sonar unit. Looking at the back of the unit, the 192 kHz transducer connector is at the far left. Plug the 192 kHz transducer in here. The center connector is for the power cable.

  • Page 9: Transducer Installation

    If the transducer is not placed in a smooth flow of water, interference will show on the sonar’s display in the form of random lines or dots whenever the boat is moving.

  • Page 10: Shoot-Thru-Hull Vs. Transom Mounting

    Shoot-thru-hull v.s. Transom Mounting (20° Transducer Only) 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 11 2. Slide the transducer between the two ratchets. Temporally 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. If it does, then the “A” position is correct for your hull.

Make certain to leave some slack inthe cable at the transducer as shown above. If possible, route the transducer cable away from other wiring on the boat.
  • Page 14 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 notice- able decrease in sensitivity. The second bottom signal may disappear and the bottom signal may decrease in intensity.

  • Page 15: Shoot-Thru-Hull Installation

    The face of the transducer should be parallel with the hull, with a minimum amount of epoxy between the hull and transducer. After the epoxy dries, route the cable to the sonar unit.

  • Page 16: Transducer Installation

    Please read these instructions carefully before installing your trans- ducer. The transducer mounting location is the most critical part of a sonar installation. If it isn’t done properly, the sonar can’t perform to its potential. ASSEMBLY 1.

  • Page 19 Air bubbles created by the movement of the boat hull against the water interfere with the sonar signal. This causes “noise” or random marks to appear on the sonar’s display. You may need to carefully view the water’s path at the transom while the boat is moving to determine the best location for the transducer.
  • Page 20 GOOD LOCATION 3. Don’t mount the transducer directly behind strakes or ribs on the bottom of the hull. Typically, a good location on aluminum boats is between the ribs closest to the engine. 4. Once you determine the best location for the transducer, hold the bracket against the transom.
  • Page 21 6. Route the transducer cable to the sonar unit. Keep the transducer cable away from other wiring on the boat, if possible. Electrical noise from engine wiring or bilge pumps can be picked up on the trans- ducer cable. This can show up as unwanted interference on the sonar display.

    ZOUT, ZIN - These keys let you zoom the screen in and out to see detail. ALARM - Press this key to activate any of the sonar alarms. PWR - This key turns the sonar unit and it's lights on and off. ENT, EXIT - These keys let you enter or erase values.

  • Page 23: Operation

    This unit has the capability to operate at both 192 kHz and 50 kHz when the optional SAM-50HPD is attached. When the sonar unit is turned on for the first time, 192 kHz only is in use. To activate the 50 kHz SAM, press the MENU key, then press the up or down arrow keys until the "CHART SETUP"...
  • Page 24 When the single frequency mode is enabled, as shown at right, adjusting sensitivity or grayline is straightfor- ward. Simply press the MENU key, then press the up or down arrow keys until the desired menu appears, then make the adjustment using the left or right arrow keys.

  • Page 25: Modes

    In this case, it's operating at 192 kHz. The word "AUTO" at the screen's top center shows that the sonar is in the automatic mode, freeing you from sensitivity, range, and noise rejection adjustments.The "192 KHZ" at the bottom of the screen shows that this chart is operating at 192 kHz.

  • Page 29: Sensitivity

    SENSITIVITY The sensitivity controls the ability of the unit to pick up echoes. A low sensitivity level excludes much of the bottom information, fish signals, and other target information. High sensitivity levels enables you to see this detail, but it can also clutter the screen with many undesired signals.

  • Page 30: Range

    EXIT key to erase it. RANGE - Manual You have complete control over the range when the sonar is in the manual mode. To change the range, first make cer- tain the unit is in the manual mode.

  • Page 31: Upper And Lower Limits

    UPPER AND LOWER LIMITS You can enter any range when the unit is in the manual mode. The unit lets you enter any upper and lower limit, provided there is at least five feet separating them, for example, from 20 to 25 feet. (On the screen below left, the upper limit is 0 and the lower limit is 60.) Using the upper and lower limit range option, we changed the range from 0 to 60 feet to 24 to 54 feet.

  • Page 32: Zoom

    Changing the upper and lower limits gives you far more control of the screen than com- petitive sonar products. You can select any segment of the water from the surface to the bottom, enlarging targets to best suit your fishing conditions.

  • Page 33: Grayline

    GRAYLINE is adjustable. Since GRAYLINE shows the difference between strong and weak signals, adjusting the sensitivity may require a different GRAYLINE level, also. The level chosen by the sonar unit at power on is usually adequate for most conditions. Experiment with your unit to find the GRAYLINE setting that’s best for you.

  • Page 34: Chart Speed

    down arrow keys until the GRAYLINE menu appears. A screen similar to the one at right appears. Press the left arrow key to decrease the gray level or the right arrow key to increase it. The percentage of GRAYLINE in use changes as the arrow keys are pressed.

  • Page 35: Fish Id

    FISH ID The Fish ID feature identifies targets that meet certain conditions as fish. The microcomputer analyses all echoes and eliminates surface clutter, thermoclines, and other signals that are undesirable. In most instances, remaining targets are fish. The Fish ID feature displays symbols on the screen in place of the actual fish echoes.

  • Page 36: Chart Setup

    See below for more information on these items. CHART CURSOR This sonar unit has a chart cursor that allows you to pinpoint a target’s depth. The cursor is simply a horizontal line that extends across the display from left to right.

  • Page 37: Display Zoom Bar

    This display comes from a separate digital sonar built into the unit (and into the optional SAM-50HPD). It displays only the bottom depth. If it loses the bottom, the last known depth will flash on the display.

  • Page 38: Alarms

    50 kHz. Press the EXIT key to erase the menu. ALARMS The sonar unit has three different types of alarms. The first is the Fish Alarm. It sounds when the Fish I.D. feature determines an echo or group of echoes is a fish. Another alarm is the Zone Alarm which consists of a bar.
  • Page 39 setting. Both depth alarms work only off the digital bottom depth signals. No other targets will trip these alarms. If you turn the digital off, the depth alarms will be inoperative. These alarms can be used at the same time or individually.

  • Page 40: Zone Alarm

    ALARM key, then highlight the "Fish Alarm" label and press the right arrow key. The unit will revert to the sonar display with the fish alarm turned on. Repeat the above steps to turn the fish alarm off.

  • Page 41: Advanced Signal Processing (Asp)

    EXIT key to erase the SCC menu. ASP (Advanced Signal Processing) The ASP feature is a noise rejection system built into the sonar unit that constantly evaluates the effects of boat speed, water conditions, and interference. This automatic feature gives you the best display possible under most conditions.

  • Page 42: System Setup

    System Information This screen shows some basic data about the sonar unit. To view this, highlight the "System Info" label on the System Setup menu, then press the right arrow key. The system info screen appears. To erase this screen, press the EXIT key.

  • Page 43: Temperature Graph

    If the transducer is one foot below the surface, and the sonar reports the water depth as 30 feet, then the depth is actually 31 feet.

  • Page 44: Calibrate Speed

    Press the right arrow key, then the up or down arrow keys until 1.0 appears in the "Adj Keel" box, as shown at right, then press the ENT key. This immediately changes the digital depth display at the top of the screen by one foot.
