Speed/Temperature Sensors

This unit can accept as many as two temperature sensors, which can be used to monitor the temperature of surface water, a live well or some other location. These units can also accept an optional speed sensor for showing speed and distance traveled. However, you can only use one ac- cessory at a time. If you would like to use a speed sensor and a second temperature sensor at the same time, you will need a combination device.

NOTE:

This unit is packed with a transducer containing a built-in temp sensor. The SeaCharter package also includes a speed sensor. If you have a FishElite 640c and want a speed sensor or additional temp sensor, see the Accessory Ordering Information in the back of this manual.

If a second temp sensor is used, it must be the model TS-2U. This model has a fixed electronic address which designates it as the second of two temp sensors. Dual temperatures are only displayed on the Full Chart page. The Large Digital page will only display the primary tem- perature sensor. See the following wiring diagram for temperature and speed sensor combinations.

The high-resolution graphics enhance the experience while providing an intuitive interface for easy navigation through its various features.

The 640cDF, a variant of the 640C, elevates the standard fish finder experience by incorporating dual-frequency sonar capabilities. This model operates on both 200 kHz and 83 kHz frequencies, allowing users to switch between narrow and wide beams based on their fishing needs. The dual-frequency technology provides a more comprehensive view of the underwater environment, making it easier to identify different types of fish and underwater structures. Additionally, the 640cDF boasts temperature sensing capabilities, giving anglers valuable data regarding water conditions that can influence fish behavior.

All models in the Eagle 640 series feature built-in GPS navigation. The integrated GPS provides a reliable mapping system that allows users to mark waypoints and create routes, significantly improving navigation efficiency. This technology is vital for those who engage in long-distance fishing trips or travel in unfamiliar waters. The GPS functionality, combined with the sonar capabilities, makes these devices essential tools for successful fishing excursions.

Furthermore, the Eagle 640 series devices come equipped with customizable display options, allowing users to tailor the information presented based on their preferences. The intuitive menu system simplifies the navigation of the device's various features, empowering users to quickly access critical data without unnecessary complications.

In summary, the Eagle Electronics 640C, 640cDF, and the 640c represent a blend of cutting-edge technology and user-centric design in the marine electronics space. With features such as high-resolution displays, dual-frequency sonar, built-in GPS navigation, and customizable settings, these devices enhance the fishing experience, making them invaluable assets for anglers and navigators alike.
