Page 9: Shoot-Thru-Hull Vs. Transom Mounting
Transducer centerline Align transducer centerline with hull bottom. However, there are times when you may need to adjust the transducer slightly higher or lower. (The slots in the mounting brackets allow you to loosen the screws and slide the transducer up or down.) If you fre- quently lose bottom signal lock while running at high speed, the trans- ducer may be coming out of the water as you cross waves or wakes.

The line at the top of the screen represents the surface. The bottom depth (as determined by the digital sonar) shows in the upper left corner. If your speed sensor is con- nected, digital displays for speed and temperature will also be shown.
-
Page 32: Dual-Frequency Split Chart (X58Df Only)
DUAL-FREQUENCY SPLIT CHART (X58DF only) This page shows sonar data from the 50 kHz transducer element on the left side of the screen and data from the 200 kHz transducer on the right side. All other functions and features are the same as the Full Chart page.
-
Page 33: Lrg Digital (Large Digital)
A speed sensor is included with the X58DF. FLASHER The Flasher page represents a flasher style sonar. A circular dial shows all returning echoes at a high screen refresh rate. It uses the Grayline feature to show weaker targets as shades of gray. The bottom depth is also shown as a digital display in the center of the circle, while tem- perature and speed are shown at the bottom.
-
Page 34: Range
RANGE When turned on for the first time, the unit automatically adjusts the depth range according to water conditions. It always keeps the bottom displayed in the lower portion of the screen. You can over-ride the automatic range control and manually select a range. To do this, press MENU keys to select the desired range.
-
Page 35: Zoom

-
Page 36
NOTE: Using the Zoom command while in auto Range mode will always enlarge the echoes near the bottom, because auto Range always keeps the bottom displayed in the lower portion of the screen. When you Zoom in manual Range mode, echoes are enlarged near the middle of the displayed range. -
Page 37: Sensitivity
SENSITIVITY Sensitivity controls the unit’s ability to pick up echoes. If you want to see more detail, try increasing the sensitivity, a little at a time. There are situations when too much clutter appears on the screen. Decreasing the sensitivity can reduce the clutter and show the strongest fish ech- oes, if fish are present.

you from turning sensitivity down too low to allow automatic bottom tracking. When you change the setting with auto turned on, the unit will continue to track the bottom and make minor adjustments to the sensi- tivity level, with a bias toward the setting you selected. Adjusting sensitivity in Manual Sensitivity Mode is similar to driving a car without cruise control —… -
Page 39: Grayline
Since Grayline shows the difference between strong and weak signals, adjusting the sensitivity may also require a different Grayline level. 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 40: Fish I.d
At left, underwater scene in normal fish arch mode. Right, Fish I.D. Fish I.D. is an easier way for a sonar novice to recognize a fishy signal return when he sees it. However, locating fish by symbol only has some limitations.
-
Page 41: Fishtrack
Does that mean Fish I.D. is broken? No — the feature is simply inter- preting sonar returns in a specific way to help take some of the work out of reading the screen. Remember: Fish I.D. is one of the many tools we provide so you can analyze your sonar returns for maximum fish finding information.
-
Page 42: Fishreveal
FISHREVEAL When displaying actual sonar returns, the FishReveal feature helps show fish targets hidden by surface clutter, thermoclines, weed beds and other cover with 10 levels of gray tones. Normal operation (with FishReveal turned off) shows the weakest ech- oes as black and the strongest in light gray. Since all weak echoes are black, fish arches show boldly against the white background.

Page 44: Noise Reject And Asp (Advanced Signal Processing)
ASP is an effective tool in combating noise. In sonar terms, noise is any undesired signal. It is caused by electrical and mechanical sources such as bilge pumps, engine ignition systems and wiring, air bubbles passing over the face of the transducer, even vibration from the engine.
-
Page 45: Alarms
ALARMS The sonar unit has two different types of alarms, fish and depth. Fish Alarm The Fish Alarm sounds a tone when a fish symbol appears on the screen. The default setting is on, but the Fish I.D. feature must be turned on for fish alarms to work.

-
Page 53: Chart Setup
If you turn on your unit before attaching a transducer, it may enter a demo mode. The words «demo mode» flash on the bottom of the screen and a sonar chart plays much like the simulator. Unlike the simulator, the demo mode is for demonstration only, and will auto- matically stop as soon as you turn on the unit with a transducer at- tached.
-
Page 54: Frequency (Change Transducer Frequency — X58Df Only)
This in turn can reduce the amount of detail seen on the sonar chart. Try this command only if you are in deep water, traveling at high speed, and notice a reduction in detail on the sonar chart.
-
Page 55: Digital Data Size For Depth, Temperature, Speed, And Distance Log
There is a common exception to these rules of thumb. Some fishermen on freshwater lakes (or the ocean) using downriggers like to see them on the sonar. In many of those cases, you’ll see a 50 kHz transducer frequency in use because the wider cone angle lets them watch the bait.

Page 57: Troubleshooting
Unit freezes, locks up, or operates erratically: 1. Electrical noise from the boat’s motor, trolling motor, or an accessory may be interfering with the sonar unit. Rerouting the power and trans- ducer cables away from other electrical wiring on the boat may help.
-
Page 58
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. -

installation methods is right for your boat. Use extreme care if mounting the transducer inside the hull, because once it is epoxied into position, the transducer usually cannot be removed. Remember, the transducer installation is the most critical part of a sonar installation! Your Skimmer transducer typically comes packaged with a one-piece stainless steel bracket for mounting it to the transom of your boat. The optional trolling motor mount uses a one-piece plastic bracket with an adj

NOTE: Some aluminum boats with strakes or ribs on the outside of the hull create large amounts of turbulence at high speed. These boats typically have large outboard motors capable of propelling the boat at speeds faster than 35 mph. Typically, a good transom location on aluminum boats is between the ribs closest to the engine. 3. The transducer should be installed with its face pointing straight down, if possible. For shoot-thru applications: Many popular fishing boat hulls have a flat

How low should you go? For most situations, you should install your Skimmer transducer so that its centerline is level with the bottom of the boat hull. This will usually give you the best combination of smooth water flow and protection from bangs and bumps. Transom Transducer centerline Hull bottom Align transducer centerline with hull bottom. However, there are times when you may need to adjust the transducer slightly higher or lower. (The slots in the mounting brackets allow you to

However, the shoot-thru-hull installation does have its drawbacks. First, some loss of sensitivity does occur, even on the best hulls. This varies from hull to hull, even from different installations on the same hull. This is caused by differences in hull lay-up and construction. Second, the transducer angle cannot be adjusted for the best fish arches on your sonar display. (This is not an issue for flasher-style sonars.) Lack of angle adjustment can be particularly troublesome on hulls th

If the transducer’s face isn’t parallel with the ground, remove the transducer and ratchets from the bracket. Place the ratchets into the holes in the bracket with the letter «B» aligned with the dot stamped in the bracket. Reassemble the transducer and bracket and place them against the transom. Again, check to see if you can move the transducer so it’s parallel with the ground. If you can, then go to step 3. If it doesn’t, repeat step 2, but use a different alignment letter until you ca

If the arch slopes up – but not back down – then the front of the transducer is too high and needs to be lowered. If only the back half of the arch is printed, then the nose of the transducer is angled too far down and needs to be raised. NOTE: Periodically wash the

hours, fill the remaining space with polyester resin. When the job is finished, the hull is watertight and structurally sound. Remember, the sonar signal must pass through solid fiberglass. Any air bubbles in the fiberglass or the epoxy will reduce or eliminate the sonar signals.

If you can’t get an acceptable bottom signal, try turning up the sensitivity by three or five keystrokes and then move the transducer around once more. If you find a spot that works, mark it and move on to step 4. If you have to turn up sensitivity by more than five keystrokes to get a good signal, the transducer should be mounted on the outside of the hull. This is especially true if you have to turn sensitivity all the way up to get a decent bottom signal. True bottom Second bottom Ma

100 grit sandpaper. The sanded hull area should be about 1-1/2 times the diameter of the transducer. The surface of the hull must be flat so the entire transducer face is in contact with the hull prior to bonding. After sanding, clean the hull and transducer with rubbing alcohol to remove any sanding debris. Spread epoxy here Sand this surface Orient the Skimmer with the nose facing the bow of the boat.

the transducer should be parallel with the hull, with a minimum amount of epoxy between the hull and transducer. 4. Apply a weight, such as a brick, to hold the transducer in place while the epoxy cures. Be careful not to bump the transducer while the epoxy is wet. Leave the weight in place for a minimum of three hours. Allow the epoxy to cure for 24 hours before moving the boat. 5. After the epoxy has cured, route the cable to the sonar unit and it’s ready to use. Power and Cable Connec

Bracket Installation Mount the unit in any convenient location, provided there is clearance when it’s tilted for the best viewing angle. You should also make sure there is enough room behind the unit to attach the power/transducer cable. (See the following drawings, which show the dimensions of a mounted X51 Pro.) Holes in the bracket’s base allow wood screw or through-bolt mounting. You may need to place a piece of plywood on the back side of thin panels to reinforce the panel and secur
