  • Page 3: Introduction

    Thank you for purchasing an X-70A 3D. Its adjustable VariView™ 3D per- spective lets you rotate the underwater picture to accommodate specific viewing needs. In addition to the 3D views, the X-70A 3D also gives you outstanding 2D detail using either the supplied 384 kHz transducer or an optional 192 kHz transducer.

  • Page 4

    If the transducer is not placed in a smooth flow of water, interference will show on the sonar’s display in the form of ran- dom lines or dots whenever the boat is moving and can completely mask the sonar image at high speed.

  • Page 5

    Transducer Assembly and Mounting The best way to install this transducer is to loosely assemble all of the parts first, place the transducer’s bracket against the transom and see if you can move the transducer so that it’s parallel with the ground. 1.

  • Page 6

    METAL WASHER RUBBER WASHERS 4. Hold the transducer and bracket assembly against the transom. The transducer should be roughly parallel to the ground. The bottom of the transducer bracket should be in line with the bottom of the hull. Don't let the bracket extend below the hull! Mark the center of the slots for the mounting holes.

  • Page 7: Sonar Unit

    SONAR UNIT MOUNTING Install the X-70A 3D in any convenient location, provided there is clear- ance behind the unit when it is tilted for the best viewing angle. Holes in the bracket base allow wood screw or through-bolt mounting.

  • Page 8: Power Connections

    POWER CONNECTIONS The X-70A 3D works from a twelve-volt battery system. For the best re- sults, attach the power cable directly to the battery. You can attach the power cable to an accessory or power buss, however you may have prob- lems with electrical interference.

  • Page 9: Keyboard Basics

    ARROW KEYS These keys are used to make adjustments on menus. ON The “On” key turns the unit on and also turns the backlights on. OFF Press and HOLD the Off key to turn the X-70A 3D off. FULL CHART This key switches the digital box between small and large digits when the 2D chart is displayed.

  • Page 10: Display

    DISPLAY - General When the X-70A 3D is first turned on, the display looks similar to the one below. The 3D screen scrolls from right to left, with the scale on the right side of the screen. The current depth beneath the transducer shows in the upper right corner of the display.

  • Page 11: Modes Of Operation

    If the speed/temperature sensor is not plugged into the X-70A 3D, then none of these will show. MODES OF OPERATION The X-70A 3D shows a sonar picture of the underwater world in 3D, 2D, Bottom Depth View, and FasTrack™...

  • Page 12

    All 2D modes show the bottom signal, structure, thermoclines, fish (both with and without the Fish ID feature), baitfish schools, and more. The 3D view shows a 3D representation of the bottom, with Fish ID symbols only. The 2D mode shows more information, the 3D mode makes it easier to visualize the bottom contour.

  • Page 13: Operation

    When the X-70A 3D is in the automatic mode, the computer inside ad- justs the sensitivity for the best setting. You can override this setting, add- ing or subtracting the amount of sensitivity the computer uses. You can also take complete control of the sensitivity level when the unit is in the manual mode.

  • Page 14: Operation

    3D OPERATION When the X-70A 3D is in the 3D mode, the Fish ID feature is always on (unless you turn it off). FishTrack (the depth numbers above the fish sym- bols) shows you the depth of the fish symbol and can be turned off, if desired.

  • Page 15: Variview

    3D VARIVIEW™ When the X-70A 3D is first turned on, the 3D screen scrolls from right to left as shown above. This view shows you the bottom contour as if your boat is travelling from the left side of the screen to the right side. The upper right corner of the screen is the right (starboard) side of your boat’s...

  • Page 17: Transducer Element Selection

    384 kHz transducer elements, or the 192 kHz transducer. (Note: 192 kHz operation requires an optional 192 kHz trans- ducer.) To select the transducer element and place the X-70A 3D into the 2D mode, press the WINDOWS key. Next, press the key next to the "2D 384 kHz"...

  • Page 18: Range - Upper And Lower Limits

    The X-70A 3D uses the following ranges: 0 - 5, 10, 20, 40, 60, 80, 100, 150, 200, 300, 400, 500, 700, and 900 feet. Upper and Lower Limits The X-70A 3D gives you added versatility with the upper and lower limits menu.

  • Page 19: Zoom - Automatic Operation

    and your new upper limit will be at the top of the screen. To change the lower limit, use the same steps as above, but press the key next to the "Set Lower Limit" menu. Press the CLR key to erase these menus or wait a few sec- onds and they will automati- cally disappear.

  • Page 20: Zoom - Manual Operation

    matically disappear from the screen or press the CLR key to erase it. 2D ZOOM - Manual Mode The zoom feature works the same in manual as it does in automatic with two exceptions. One, since the unit is in manual, the unit won’t change the range to keep the bottom signal on the display.

  • Page 21: Fastrak

    You can adjust the range, however this is the only adjustment you can make on this screen. The X-70A 3D au- tomatically sets the sensitivity level. FASTRAK™ The FasTrak™ view converts all echoes to short horizontal lines.

  • Page 22: Stop Chart

    The unit returns to the last used sonar display. ALARMS The X-70A 3D has three different alarms. The first is the Fish Alarm. It sounds when the Fish I.D. feature places a fish symbol on the screen. (This alarm only works in the 2D and 3D modes.) Another alarm is the Zone Alarm which consists of a bar on the right side of the screen.

    "Alarms" label. Now press the key next to the "Shal Alarm" menu until the check mark moves to the “OFF” box. Press the CLR key to return to the sonar display. Remember, the shallow and deep alarms adjust exactly the same. The only difference is the shallow alarm sounds when the bottom signal goes shallower than the shallow alarm’s setting.

  • Page 25: Fish Alarm

    FISH ALARM The fish alarm sounds a distinctive tone when the X-70A 3D places a fish symbol on the display. A different tone sounds for each of the four fish symbol sizes. To turn the fish alarm on, first press the MENU key, then press the key next to the "Alarms"...

  • Page 26: Display Contrast

    Any targets the microcomputer determines are fish will be dis- played as fish symbols. Remember, the Fish I.D. feature can’t be used when the X-70A 3D is in the manual mode. If you turn the Fish I.D. feature on when the unit is in manual, the microcomputer will turn the automatic feature on.

  • Page 27: View Options

    DIGITAL BOX OPTIONS The X-70A 3D can display the depth, speed, surface water temperature, and distance log on all sonar screens, including the 2D, 3D, Bottom Depth View, and FasTrak.

  • Page 35: Reset Distance Log

    Press the CLR key to exit the menu. RESET DISTANCE LOG The X-70A 3D can display the log (distance travelled) in the digital block if the optional speed/temperature sensor is installed. This feature starts counting distance as soon as the unit is turned on.

  • Page 36: Simulator

    3D SIMULATOR The X-70A 3D has a built-in simulator for the 3D display. When this simu- lator is turned on, a realistic 3D view scrolls across the screen. The digital depth display shows the simulated bottom depth, and fish symbols ap- pear on the display.

  • Page 37: Troubleshooting

    This can cause the unit to eliminate weaker signals such as fish or even structure from the display. 3. The water may be deeper than the sonar’s ability to find the bottom. If the sonar can’t find the bottom signal while it’s in the automatic mode, the digital will flash continuously.

  • Page 38

    1. The transducer may be in turbulent water. It must be mounted in a smooth flow of water in order for the sonar to work at all boat speeds. Air bubbles in the water disrupt the sonar signals, interfering with its ability to find the bottom or other targets.

  • Page 39: Noise

    Make certain the engine is off, also. Turn your X-70A 3D on, then turn off ASP (Advanced Signal Processing). There should be a steady bottom signal on the display. Now turn on each piece of electrical equipment on the boat and view the effect on the sonar’s display.
