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. SPECIFICATIONS Dimensions..................................... 5 7/8" H x 7 3/4"W x 3 7/8"D Transmitter Frequency .................... 384 kHz and 192 kHz Transmitter Pow

Transducer Location 1. The transducer must be placed in a location that has a smooth flow of water at all times. 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. 2. The transducer should be installed with its face pointing straight down, if possible. 3. Make certain the chosen location doesn’t interfere with the boat’s tr

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. Press the two small plastic ratchets into the sides of the metal bracket as shown below. Notice there are letters molded into each ratchet. Place each ratchet into the bracket with the letter “A” aligned with the dot stamped into the metal bracket.

METAL 3. Once you determine the WASHER NUT correct position for the ratchets, assemble the transducer as shown at left. Do not tighten the lock nut at this time. RUBBER METAL WASHERS WASHER BOLT 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. D

6. Route the transducer cable to the sonar unit. 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. Use caution when routing the transducer cable around these wires. IMPORTANT! Clamp the transducer cable to the transom close to the transducer. This can prevent the transducer from entering the boat if it is knocked off at high speed. 7. Make a te

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. Therefore, it’s safer to go ahead and attach the power cable directly to the battery. If the cable isn’t long enough to reach the battery, splice #18 gauge wire onto it. The power cable has two wires, which are red and black. Red is

KEYBOARD The keyboard is arranged for convenient operation. A ten-key keypad on the right side of the screen lets you enter numbers. Arrow keys beneath the keypad are used to adjust features. The keys in the left column are used to select menu features. The keys along the bottom of the screen let you select the basic sonar functions. SENS Press this key to adjust the unit’s sensitivity. RANGE This key lets you adjust the range shown on the display. ZOOM This switches the chart between two time

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. A fish symbol to the left of the depth shows that the Fish ID feature is on. The word “AUTO” signifies that the automatic function is on, keeping the bottom on the display at all times. If the computer identifies targets

screen, showing the distance behind the boat. 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™ modes. The 2D and Bottom Depth Views can use either the 384 or 192 kHz transducer (if the optional 192 kHz transducer is attached). The 3D mode is al- ways 384 kHz. To switch be- tween the different modes, first press the WINDOWS key. P

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. The Bottom Depth View as shown at right displays the depth at the top of the display in large digits. The graph scrolls at high speed. Note that this graph only shows the bot- tom sig

OPERATION The Automatic and Sensitivity features used on the X-70A 3D are the same for all modes of operation. This section will explain these features. For information on features specific to different modes, see the 2D or 3D operation sections. AUTOMATIC The X-70A 3D adjusts the sen- sitivity and range to keep a detailed bottom signal on the display when the automatic feature is on. This is enabled when the unit is first turned on. You can turn this feature off to gain greater control over the

To adjust the sensitivity, press the SENS key. A menu appears on the right side of the screen as shown on the previous page. Press the right arrow key to increase it, the left arrow key to decrease it. When you have it changed to the desired level, press the CLR key to erase the menu or wait a few seconds for it to automatically clear. 3D OPERATION When the X-70A 3D is in the 3D mode, the Fish ID feature is always on (unless you turn it off).

To use the zoom feature, first press the ZOOM key, then press the key next to the zoom menu that appears in the lower left corner of the display as shown at right. This switches the unit to the 2X zoom mode. This enlarges all echoes on the screen to twice their nor- mal size. If you press the key again while the menu is showing, the unit will switch to the 4X zoom mode. This enlarges all echoes four times th

(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" label or the "2D 192 kHz" label. The screen shown at right ap- pears. If you want to use only the cen- ter two transducer ele

few seconds and the menu will automatically disappear from the screen or press the CLR key to erase it. Manual mode When the X-70A 3D is in the manual mode, any range can be selected. The unit will leave the range setting you choose, but it won't keep the bottom on the display. For ex- ample, if the range is 0 - 60 feet, and the bottom signal goes from 55 to 70 feet, once the bottom goes deeper than 60 feet, it won't show on the display. To change the range, first press the RANGE key. A screen s

One, since the unit is in manual, the unit won’t change the range to keep the bottom signal on the display. Two, you can adjust the zoom “window” to any desired depth. To zoom the screen in the manual mode, first press the ZOOM key. A screen similar to the one on the previous page appears. You’ll notice a new label on t
