Humminbird SmartCast RF45 Advance Remote Sonar Sensor (Discontinued by Manufacturer)
With the Humminbird RF45 Advance Remote Sonar Sensor (RSS), you get an even better performance from your SmartCast wireless remote fish finder. This unit provides you with a greater depth capability, and longer in-water usage time than the RSS device that originally came with your SmartCast system. The RF45 features water surface temperature readings, and programmable two-channel operation so you can fish with a buddy without crossing signals, as well as a flashing, internal light that you can switch on or off for night fishing. The RF45 is designed for use with Humminbird's SmartCast RF15, RF25, RF35 fish finders, although it will work as replacement sensor for the RF10, RF20 and RF30 as well, but will not provide temperature readings or extended depth performance. The RF45 is intended for use in the US and Canada only, and is backed by Humminbird's one-year limited warranty.
