1 INTR ODUCTION Thank you f or purchasing an X-70A 3D . Its adjustable V ar iView™ 3D per- spective lets y ou rotate the underwater picture to accommodate specific viewing needs . In addition to the 3D views , the X-70A 3D also giv es yo u outstanding 2D detail using either the supplied 384 kHz transducer or an optional 192 kHz transducer . SPECI[...]

2 T ransducer Location 1. The transducer must be placed in a location that has a smooth flo w of w ater at all times. If the transducer is not placed in a smooth flow of w ater , interf erence will show on the sonar’ s display in the f orm of ran- dom lines or dots whene ver the boat is mo ving and can completely mask the sonar image at high spee[...]

3 T ransducer Assembly and Mounting The best wa y to install this transducer is to loosely assemb le all of the par ts first, place the transducer’ s brack et against the transom and see if you can mo v e the tr ansducer so that it’ s par allel with the ground. 1. Press the two small plastic r atchets into the sides of the metal bracket as show[...]

4 3. Once you determine the correct position f or the ratchets , assemble the transducer as sho wn at left. Do not tighten the lock nut at this time . NUT MET AL W ASHER R UBBER W ASHERS MET AL W ASHER BOL T 4. Hold the transducer and brac ket assemb ly against the transom. The transducer should be roughly parallel to the ground. The bottom of the [...]

5 6. Route the transducer cab le to the sonar unit. If possible , route the transducer cab le awa y from other wir ing on the boat. Electr ical noise from the engine’ s wiring, bilge pumps, VHF radio wires and cables, and aerators can be pic ked up by the sonar . Use caution when routing the transducer cab le around these wires. IMPORT ANT! Clamp[...]

6 PO WER CONNECTIONS The X-70A 3D works from a twelve-v olt batter y system. F or the best re- sults, attach the po wer cable directly to the battery . Y ou can attach the po wer cable to an accessory or power buss , howe ver y ou may hav e prob- lems with electrical interference . Therefore , it’ s safer to go ahead and attach the pow er cable d[...]

7 KEYBO ARD The ke yboard is arranged f or con v enient oper ation. A ten-key k eypad on the right side of the screen lets you enter numbers . Arrow k eys beneath the ke ypad are used to adjust features . The keys in the left column are used to select menu f eatures. The keys along the bottom of the screen let you select the basic sonar functions .[...]

8 DISPLA Y - General When the X-70A 3D is first turned on, the display looks similar to the one below . The 3D screen scrolls from r ight to left, with the scale on the right side of the screen. The current depth beneath the transducer shows in the upper right cor ner of the displa y . A fish symbol to the left of the depth shows that the Fish ID f[...]

9 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 OPERA TION The X-70A 3D shows a sonar picture of the underw ater wor ld in 3D , 2D , Bottom Depth View , and FasT rack™ modes . The 2D and Bottom Depth Views can use either the 384 or 192 kHz t[...]

10 All 2D modes show the bottom signal, structure, thermoclines, fish (both with and without the Fish ID f eature), baitfish schools, and more . The 3D view sho ws a 3D representation of the bottom, with Fish ID symbols only . The 2D mode shows more inf or mation, the 3D mode makes it easier to visualize the bottom contour . The Bottom Depth View a[...]

11 OPERA TION The A utomatic and Sensitivity features used on the X-70A 3D are the same f or all modes of operation. This section will e xplain these f eatures. F or inf or mation on f eatures specific to diff erent modes, see the 2D or 3D operation sections . A UT OMA TIC The X-70A 3D adjusts the sen- sitivity and range to k eep a detailed bottom [...]

19 mation only . No fish, structure, or any echoes other than the bottom signal appear on this screen. Y ou can adjust the range , howe ver this is the only adjustment y ou can make on this screen. The X-70A 3D au- tomatically sets the sensitivity le vel. F ASTRAK™ The F asT r ak™ view con ver ts all echoes to shor t hor izontal lines. T ypical[...]

20 gets appear as shor t, thin lines; usually for v er y shor t periods of time. The bottom echo usually looks like a slice tak en from the 2D screen. Surf ace clutter appears at the top of the screen, near the picture of the boat. Using the F astrak screen combines the “instant read” of a flasher with the v ersatility and conv enience of a liq[...]

21 The depth alarms sound a tone when the bottom signal goes shallow er than the shal- low alarm’ s setting or deeper than the deep alarm’ s setting. F or e xample, if you set the shallow alarm to ten feet, the alarm will sound a tone if the bottom signal is less than ten f eet. It will continue to sound until you m ute it or the bottom goes de[...]

32 The ASP f eature has two le v- els - Low and High. If you ha ve high noise le vels, try using the “High” ASP setting. Howe ver , if you are ha ving trouble with noise , we suggest that you take steps to find the interf er- ence source and fix it, rather than continually using the unit with the high ASP setting. How ev er , there are times wh[...]

33 mark is on the desired range. Press the CLR ke y to e xit the menu. RESET DIST ANCE LOG The X-70A 3D can displa y the log (distance trav elled) in the digital block if the optional speed/temperature sensor is installed. This f eature star ts counting distance as soon as the unit is turned on. T o reset the distance log to zero , press the MENU k[...]

34 3D SIMULA T OR The X-70A 3D has a built-in sim ulator f or the 3D display . When this simu- lator is turned on, a realistic 3D view scrolls across the screen. The digital depth displa y shows the simulated bottom depth, and fish symbols ap- pear on the displa y . IMPORT ANT! Do not use the simulator when na vigating! T o turn the 3D simulator on[...]

35 TROUBLESHOO TING If your unit is not w or king, or if you need technical help , please use the f ollowing troubleshooting section bef ore contacting the f actor y customer service depar tment. It may sa v e y ou the troub le of returning your unit. Unit w on’t turn on: 1. Check the po wer cable’ s connection at the unit. Also chec k the wiri[...]

36 manual mode , then change the range to a realistic one , (for e xample , 0-100 f eet) and increase the sensitivity . As you mov e into shallower w ater , a bottom signal should appear . 4. Check the battery voltage . If the voltage drops , the unit’ s transmitter pow er also drops, reducing its ability to find the bottom or targets . Bottom ec[...]

37 NOISE A major cause of sonar problems is electrical noise. This usually appears on the sonar’ s displa y as random patter ns of dots or lines. In sev ere cases, it can completely cov er the screen with black dots , or cause the unit oper- ate erratically , or not at all. T o eliminate or minimize the effects of electrical noise, first try to d[...]
