POWER CONNECTIONS Twelve volt DC power should be supplied by the boat's electrical system. The power cable may be attached to an accessory or power buss, but if you have problems with electrical interference (random dots or lines that show whenever the boat's engine or other accessory is on), the cable should be attached directly to the b[...]

SPECIFICATIONS BASIC OPERATION Dimensions 5¾"H x 8°/16"W x 2%"D Weight 1¾ pounds When first turned on, the X-3 automatically adjusts the sensitivity, range, Transmitter 192 kHz and chart speed according to water and bottom conditions. In fact, it can be left in this mode and it will track the bottom and display it at all times, Ou[...]

SENSITM BAR •'i1F9i1'1bth' AUTO j'tU' Figure 2 SENSITIVITY When first turned on, the X-3 is in the AUTO SEARCH mode. This means the sensitivity and range are being automatically adjusted by the micro- computer to find and lock onto the bottom. The sensitivity can be left in the automatic mode, or it can be manually adjust[...]

SURVEYING A LAKE The most successful anglers on any lake or reservoir are those who fish it day after day and year after year until they learn the hot spots that pro- duce fish consistently. They discover through experience where, and at what depth, they can expect to find the kind of fish they want at any sea- son. And they realize that these prod[...]

LCHART p SLOW STOP I FAST RESUME For example, the 9 key has a small label beneath the number nine that says "LIGHT". If you press the 9 key by itself, the X-3 thinks that you want the number 9. However, if you press the 2nd key first, then press the nine key, the X-3 will turn on the lights in the display. The 2nd key just reas- signed th[...]

SURFACECLUTTER The markings at the top of the screen represent the surface of the water which can extend many feet below the surface. This can interfere with fish signals or other targets. It's called Surface Clutter and is caused by algae, plankton, air bubbles caused by wave action or boat wakes, bait fish, or temperature inversions. These m[...]

SCALE Remember, there must be some movement between the boat and the fish There are ten scale markers printed on both sides of the X-3's display to help determine what the depth of a target is. For example, if the depth range is 0 to 60 feet, then each mark is equal to six feet. If the target (such as a fish) was next to the 5th line, then it [...]

FISH SIGNALS For example, to set the range from 0 to 31 feet, press 3-1 -LOWER LIMIT. The signals displayed on the X-3 by fish can be identified by various shaped markings in certain patterns, as opposed to random marks created by noise, or the solid, continuous markings made by the bottom. Individual fish can, at times, be distinguished by a chara[...]

Example: Set range to 16 to 31 feet Press: 1-6-UPPER LIMIT then 3-1 - LOWER LIMIt Figure 8 UPPER LIMIT NOTE: When the X-3 is in the AUTO RANGE mode, the upper limit may be changed at anytime. If the upper limit is changed while the unit is in the AUTO RANGE mode, the X-3 will continue to select a lower limit that will keep the bottom displayed in t[...]

TRANSDUCERS AND CONE ANGLE The sound waves from the transducr go down ihto the water in a cone shaped beam, much like the beam frOm a flashlight The angle betWeen the outside edges of the cone is called the cone angle. Lowrance offers a choice of transducers with either an 8 or 20 degree cone angle that will interchange with any! of the 192 kHz son[...]

To turn the digital display off, or back on again, press 2nd-5. N OTE Even if the digital numbers are not being displayed on the screen, the digital sonar will still continue to function. If the digital loses the bottom signal, the chart display will stop until the digital finds the bottom. If the digital numbers are being displayed on the screen, [...]

AUTO RANGE WITH ZOOM BOTTOM TRACK An optional Auto Range feature is AUTO RANGE with ZOOM BOTTOM TRACK. When the X-3 is in the auto-range mode, it picks a lower limit range that will keep the bottom signal in the lower 4/5 of the screen. The upper limit is normally set to zero, unless you have changed it However, a "window" can be used to [...]

If the chart alarm is set off by a fish or the bottom, the alarm will sound and the ALARM can be seen at the bottom of the display lithe range is changed, the chart alarm may need to be changed also, since it operates independently and does not track range sethngs. I'll The note key turns the audible tone off or on. When the alarms are first s[...]

r71 FASTRAK FASTRAK J The FASTRAK causes the X-3 to display the bottom, fish, trees, or other echoes including the bottom signal will be converted into short, straight horizontal lines. As the bottom or other echoes moves shallow or deeper, the lines will rise or fall accordingly. This gives quick, precise depth information at a glance. If the auto[...]

19 LIGHT LIGHT A light is provided for operation of the X-3 at night. When the unit is first turned on, the lights will flash for 6 seconds. Press the 2nd-9 keys and the lights will stay on. To turn the lights off, press the 2nd-9 keys. The lights will also go off when the X-3 is turned off. DISCRIMINATION Noise is quite often the biggest complaint[...]
