1 Introduction

Congratulations on choosing a Northstar fishfinder. For maximum benefit, please read this manual carefully before installation and use.

This manual describes how to install and set up the Explorer 435 or Explorer 438. Refer to seperate Transducer Installation Instructions supplied with the transducer.

1-1 Benefits of the Explorer 435 and Explorer 438

This manual also explains how to operate the Explorer 435 and Explorer 438 effectively and gives troubleshooting and performance tips.

Important

It is vital to the performance of the fishfinder that the transducer is installed in the best location. Please follow the installation instructions very carefully.

The Explorer 435 and Explorer 438 are high quality fishfinders that are supplied with a transducer. Both use TFT (Thin Film Transistor) technology to provide a color display for easy daylight viewing. The LED backlight can be dimmed for night fishing. The bracket mounting option also allows the fishfinder to be tilted and swivelled for optimum viewing.

The colors on the sonar displays are cus- tomizable, with a choice of four 16 color palettes and one 8 color palette. The colors represent different signal strengths, making the sonar displays easy to interpret.

This capability, combined with a variable power output of up to 200 W RMS, ensures that the Explorer 435 and Explorer 438 operate effectively in shallow and deep water.

The Explorer 435 and Explorer 438 can detect the bottom to a depth of 600 feet (180 metres) depending on the clarity of the water and the type of transducer used.

The Northstar fishfinder can be used to find fish, to locate features on the bottom such as reefs or wrecks and to help recognize favourite fishing spots from the bottom profile.

The Northstar fishfinder can also assist with navigation by providing depth information to

CAUTION

IMPORTANT NOTE ON USE. While any fishfinder can be used as an aid to navigation, accuracy can be limited by many factors, including the location of the transducer. It is the user’s responsibility to ensure the Northstar fishfinder is installed and used correctly.

help identify the depth contours marked on charts.

With the optional fuel kit, the Explorer 438 also becomes a sophisticated and easy-to-use fuel computer.

All of the Northstar 400 Series fishfinders use proprietary SBN Technology for sonar processing to improve Signal enhancement, Bottom recognition and Noise rejection.

SBN Technology uses digital adaptive filter algorithms to enhance all returned signals. At the same time, SBN Technology uses active noise control to reject interference, which can often be mistaken by fishfinders for true returns.

Using SBN Technology, the fishfinder analyses the reflections from each pulse, filters false returns and displays what is in the water under the boat. See section 4-1 Interpreting the display, for more information.
