USING THE PRO FLASHER
The Pro Flasher differs from LCD depthsounders in two important ways: Operation of the
unit is completely manual. Adjustment of the sensitivity and noise reject controls, and
interpretation of the information displayed is entirely up to the user. Also, there is no history
retained on-screen. Information displayed is in the form of instantaneous flashes of light on the
dial - targets beneath your boat will appear on-screen for only as long as they are reflecting the
sonar signal.
As with any sonar product, the best way to learn to use the Pro Flasher is to operate in a
familiar area and study the information presented on the display. As you gain experience with the
unit you will be able to quickly analyze the underwater situation, and understand the conditions
that lead to more productive fishing.
The Pro Flasher uses a super-bright LED light source to indicate sonar returns. Since the
display is naturally "light emitting", it is ideal for use at night or in low- light situations. The rubber
lens hood prevents washout in even the brightest sunlight.
As with all Humminbird products, all moving parts are ruggedized for tough shock and
vibration endurance, and special components allow the Pro Flasher to operate at temperatures
more extreme than you are likely to encounter.
Your Pro Flasher may be used on an existing Wide Eye, Wide View or Wide Vision
mounting base. Once mounted it will automatically sense and use the 200 KHz 16° element of
the dual beam transducer. The Pro Flasher mounting base can only be used with the Pro Flasher
unit.
CONTROLS
The Pro Flasher uses two simple controls to vary the display of sonar information:
Sensitivity/On-Off, and Noise Reject.
The Sensitivity/On-Off control serves as both the power switch for the unit as well as the
variable sensitivity control. This is very similar to the volume control on a radio. Increasing the
sensitivity is similar to turning up the volume.
Adjustment of the Sensitivity control is largely a matter of personal taste and experience.
Lower sensitivity settings will present a clean display with only large returns such as the bottom
visible on-screen. Higher sensitivity settings will display progressively smaller signal returns, at
the expense of cluttering the display with information.
The depth of the water will affect the sensitivity setting you choose. Shallow water
requires a lower setting, while deeper water requires a higher setting since some of the sonar
signal will be absorbed or deflected.
Also, the water condition- clear, murky, salt, fresh, etc. will affect the amount of sensitivity
required.
The other control is the Noise Reject. Adjustment of this control is not normally necessary
in the operation of your Pro Flasher. The variable noise reject feature allows you to filter out
electrical interference caused by the boat motor and other electronic devices on your boat.
Noise is normally seen in the form of concentric light patterns that slowly revolve around
the dial. If noise is present, you can reduce it's effect on the Pro Flasher by turning the Noise
