NOTE: This configuration of the Northstar Explorer 443df is packaged with a plastic dual-frequency transom mount transducer that provides depth, temperature, and speed readings. If you would prefer another transducer type, or already have one, click here to see the unit without it.

Whether you're looking for single or dual frequency, Northstar has an affordable, grayscale fishfinder model for you.
Explorer 443d/443df Features:
Dual Frequency
Pixels, Power and Ping-rate. Northstar's range of grayscale fishfinders offer outstanding performance in each category:
- 360 x 240 pixels for best target definition
- 250 W RMS output power for excellent depth performance
- 50 soundings per second (or pings) for greater coverage.
The Explorer 443d offers depth and temperature features while the advanced Explorer 443df also provides speed and log functions. With an optional fuel kit added, the Explorer 443df also offers gasoline and SmartCraft fuel management capabilities.
Dual Frequency = Dual Beam Width
Both units incorporate selectable frequency to allow the fisherman to adjust the sonar beam width with a standard dual frequency transducer. Widen or narrow your search area by selecting either 83 kHz or 200 kHz for a beam width of 20° or 14°.
