Founded in 1965, Vexilar, Inc. has a long history of bringing revolutionary technology to the sport fishing industry. Just some of the Vexilar firsts include: the first liquid crystal display, the first fish alarm, the first three color display, and the first CRT and straight...
Page 2: General Description
The output frequency of 107 KHz is much lower than most depthfinders of today. This is designed to give more output power and a greater area of coverage. The 107 Pro can truly "arc" fish and does not need to use artificial fish symbols.
Page 3 Clean Echo feature to eliminate interference All told, the 107 Pro is a powerful tool for visualizing structure and fish, in almost all situations. Quality con- struction and superior product support. Long Vexilar tra- ditions that go with this unit, and everything else we pro- duce.

Page 5: Unit Installation
INSTALLATION You will need to find a place to mount the 107 Pro that will make it easy to view and reach. You must provide the unit with power and mount the transducer and sensor assembly in an effective location.
Page 6: Mounting The Sensor Box
MOUNTING THE SENSOR BOX The sensor box needs to be located within three feet of the main unit. It is recommended that it be fastened to a sturdy surface. You can mount it, using the screws pro- vided, to a flat surface or you can simply tie it to a frame or wire harness, using cable ties which are not provided.
Page 7: Attaching The Sensor
ATTACHING THE SENSOR ASSEMBLY The speed and tempera- ture sensor assembly attach- es to the transducer as shown. Pinch, or squeeze, together the tabs at the top of the sensor and slide the assembly down into the tracks on the back of the transducer.
Page 8: Mounting The Transducer
MOUNTING THE TRANSDUCER The 107 Pro transducer is designed to be mounted on the transom of the boat. The shape will allow a clear depth reading at any boat speed, if properly installed. Locate a spot similar to the one in figure 7. Keep in mind that you need clear water flow across the face of the trans- ducer to insure a clear reading at all speeds.
Page 9 so that when the bottom of the transducer is flush with the bottom of the boat the holes are located at the bottom of the bracket slots. This gives you room to "fine tune" the position of the transducer and optimize your reading after you've put the boat back in the water.
Page 10 PORTABLE MOUNTING An optional suction cup bracket can be used to temporarily attach a transducer to the transom or side of the boat. The cups should be placed in a location where they will not be torn off when the boat goes high speed, but still just low enough to maintain the high speed reading.
Page 11 Using an epoxy or silicone glue, make a puddle about the same diameter as the transducer on the hull. Place the transducer in the glue. Press it down firmly, gently twisting it back and forth, making sure that there are no air bubbles in the glue between the transducer and the hull.
Page 12: Operation
Figure 11 shows the main controls of the 107 Pro. POWER - OFF / ON Turns the 107 Pro OFF and ON. Press the ON button to turn the unit on. You will hear a short beep when the unit powers on. Press the OFF button to turn the unit off.
Page 13 GAIN CONTROL The 107 Pro comes selected from the factory to run in automatic gain mode. The unit will monitor the conditions and adjust the gain, or sensitivity, to an optimum level. If you wish, you can over ride this feature in the MENU set- tings and adjust the gain manually.
Page 14 ZOOM The 107 Pro has three different Zoom Zones. You can select to view only the top half, middle half, or bottom half of the depth. Using a Zoom Zone, effectively, doubles the display resolution, making things appear twice as large.
Page 15: Menu Functions
MENU FUNCTIONS Press the MENU button to enter the first menu page. Press the MENU button again to enter the second menu page. AUTO GAIN Press MENU, then, the 1, or DEC, button to enter the AUTO GAIN submenu. This feature has three available settings.
Page 16 BOTTOM ALARM Press MENU, then the 3, or SLOW, button to enter the Bottom Alarm submenu. Press the 1 button turn this fea- ture off, the default. Press the 2 button to turn this feature There are two values to be entered in the alarm settings. There are also several different ways in which the alarm works, depending on the depth values you enter.
Page 17: Fish Alarm
Example 3 - To set the alarm to sound whenever the depth gets less than five feet or more than fifteen feet, press the 4 button to enter the upper alarm limit. Press the 1 but- ton and then the 5 button to enter the value of fifteen. Press the SET button to enter this value.
Page 18 LIGHT To turn on the backlight, for night use, press the MENU button, then, the 5 button to enter the Light submenu. Press the 2 button to turn it on and the 1 button to turn it off. CONTRAST To adjust the liquid crystals display contrast, press MENU, then, the 6 button to enter the Contrast adjustment submenu.
Page 19: System Reset
3 button to clear the Log and start a new read- ing. SIMULATION The 107 Pro has a built-in Simulator to help you learn or demonstrate the functions of the unit. The Simulator is a short program which simulates a real world situation. All of the front panel controls and menu functions can be used with the simulator.
Page 20 CLEAN LINE Clean Line is a feature which can help determine the hardness of the bottom. Clean Line "cleans out" the target signal on harder objects. A hard bottom will appear cleaned out in the center. A soft bottom will be all black. Press the MENU button twice, then, the 3 button to enter the Clean Line submenu.
Page 21 UNIT You can select the unit of measurement for depth, tem- perature, and speed. Press MENU twice, then, the 6 but- ton to enter the Unit submenu. For Depth, you can select Feet, Fathoms, or Meters. Press the 1 button for Feet, the 2 button for Fathoms, or 3 for Meters.
Page 22: Typical Indications
SEEING FISH Fish passing through the cone will appear as an arc, or partial arc. Here is how it works. The 107 Pro has allot of power and a very wide cone angle. When the fish appears at the edge of the cone it is far away from the transducer.
Page 23: Surface Clutter
It can, however, make things difficult to see in shallow water. HIGH SPEED OPERATION The 107 Pro can read depths at almost any boat speed. Due to the limited speed of the display, the displayed bot- tom may be some distance behind you, depending on how fast the boat is traveling.
Page 24: Shallow Water Operation
Readjustment of the transducer mounting should solve this problem. SHALLOW WATER OPERATION When the 107 Pro is in the automatic range and gain modes, it automatically senses the bottom depth and tries to keep the best view at all times. Although the display may...
Page 25 ICE FISHING The stable platform of ice lets you concentrate on your bait and the fish around it. The bottom becomes less impor- tant because it never changes. The only movement on the display is of your bait and fish. Unlike open water use, the direction in which the trans- ducer is pointed is very critical.
Page 26: Maintenance
MAINTENANCE Maintenance for the 107 Pro is very simple. There, sim- ply, is not that much to maintain. Because of this, problems can sneak up on you if you're not careful. The unit should be removed whenever the boat is parked to guard against theft.
