Hummingbird pro 128 fish finder manual

If the unit functions well at low speeds but begins to skip or miss the bottom at higher speeds, the transducer needs to be moved. If depth performance is required, test the fishfinder in water at the desired depth. Extension cables are available. Page 13 not included for the protection of the unit Figure Humminbird is not responsible for over voltage or over current failures.

In order to minimize the potential for interference with other marine electronics a separate power source such as a second battery may be necessary. Page 14 5. Install the control head by sliding it onto the mounting bracket until it is fully seated.

To remove the unit simply depress the latch on the rear of the unit and lift Figure Your Humminbird is now ready for operation. Page 15 Note: it is often necessary to make several incremental transducer adjustments before optimum high-speed performance is achieved.

Important: For Transom Mount transducer installations, install the third mounting screw after the final transducer adjustments.

Humminbird 3 Humminbird Lane Eufaula, Alabama Page 16 The Wide is completely automatic and easy to use. Simply press the POWER button and the unit will locate and track the bottom from 2' to ' changing ranges as necessary, display any structure or suspended fish and work at speeds from 0 to over 70 mph.

Page 17 Simulator mode, power the unit off. This type of display provides outstanding viewability in all light conditions over a wide range of temperatures. Page 18 The best way to learn to interpret structure is to operate the Wide over a variety of known conditions and experiment with user functions to best represent those conditions on-screen. Page 19 The backlight is very effective for low-light and nighttime operation.

When the backlight is on, the Wide will consume more power than with the backlight off. This is important when using the Wide in a portable configuration powered by a separate battery, or when powering the unit from a trolling motor battery. The Wide automatically adjusts the level of receiver sensitivity based on a number of factors including the depth of the water and the level of noise present.

Noise can be caused by other electronic devices, engines, trolling motors, propeller cavitation and hydrodynamic flow among others. Page 21 The Wide automatically adjusts the depth range depending on the depth of the water. Page 22 '' depth range is in use, the Zoom range is 30', and if the ' range is in use, the Zoom range is 60'. The Wide shows Zoom range in conjunction with the full depth range. The Zoom range is shown on the left side of the screen and full range information is shown on the right side of the display.

Page 23 Fish Alarm. Once the Fish Alarm is enabled, the Wide emits an audible beep when the selected size fish symbol appears on-screen. The sound is slightly different for each of the three fish symbol sizes, so with practice, it is possible to distinguish the size of the detected fish without looking at the unit.

Page 24 Use Diagnostic while running the boat at high speeds to show the voltage gain. Also, if you are using the Wide in portable configuration or from the trolling motor battery, Diagnostic can be used to evaluate the health of the battery by showing the current voltage.

The Tracker unit automatically adjusts the level of receiver sensitivity based on a number of factors includ- ing the depth of the water and the level of noise present. If additional time is needed to study a menu, press and hold the MENU button and the menu will remain on-screen indefinitely.

Using manual Depth Range control, you can view sonar information from the area near the surface in great detail. Zoom can either operate automatically, in which the Zoom range is constantly adjusted to show the bottom, or manually, in which the user controls the location of the Zoom range. Fish Alarm. The Fish Alarm alerts you to the presence of fish, or other targets not con- nected to the bottom.

The display contrast will change as the adjustment is made so the optimum level of contrast can be achieved. There is no interpretation made by the unit. The big numerals occupy space on the display that could be used for the graphics area. Hence, the small numerals option. With small numer- als selected, a greater amount of the display area is available for the graph- ic view.

A negative value equal to the distance from the transducer location and the deepest point of the hull will have the same effect as mounting the transducer at the deepest point. If a series of dashed lines is shown, no transduc- er is connected or there is a problem with the transducer or cable. If you are using multiple transducers, switch between transducers to confirm the connections for each. Do not use a chemical glass cleaner on the lens.

Chemicals in the solution may cause cracking in the lens of the unit. Nothing happens when I turn the unit on. Check the power cable connection at both ends. Be sure the cable is connect- ed correctly to a reliable power source—red lead to positive, black lead to neg- ative or ground. Also, in very deep water, it may be nec- essary to manually increase the sensitivity setting to maintain a graphic depiction of the bottom. My unit loses power at high speeds. Your Tracker unit has over-voltage protection that turns the unit off when input voltage exceeds 20 VDC.
