USING THE 405SX

MENU FUNCTIONS

Decreasing the value to a number less than zero shows fewer fish symbols on-screen. In this case smaller sonar returns are disregarded. This is useful for eliminating many small sonar returns when seeking larger species of fish.

The 405SX remembers this selection even when the unit is powered off.

Numeral Size. Two options are available: Big and Small. The factory setting is Big. With this setting, the digital depth and speed and temp numerals are drawn large enough to be read from across the boat. The big numerals occupy space on the display that could be used for the graphics area. Hence, the small numerals option. With small numerals selected, a greater amount of the display area is available for the graphic view. This effectively increases the display resolution of the unit.

Numeral Size settings are remembered when powered off.

Units Speed. Units of Speed allows the selection of MPH (statute miles per hour), or KTS (nautical miles per hour). Use the Arrow buttons to highlight the desired selection.

Speed Offset. The Speed Offset option allows the user to compensate for differences in hull design, and its effect on the accuracy of the speed measurement. If there is a discrepancy between the indicated speed and another speed measurement device on the boat, the speed measurement can be varied to improve accuracy. Remember, the speed paddle wheel measures speed through the water, not speed over ground.

Speed offset is remembered after power is disconnected.

Depth Offset. The Depth Offset allows the user to select the point on the boat from which the depth measurement is made. Selecting a positive value adds distance to the measurement. If the transducer is mounted 1 metre beneath the waterline, a positive 1 will show the correct depth from the surface of the water.
