Functionality of the Deeper CHIRP+ 4
The Deeper CHIRP+ 4 is a sophisticated tool for serious anglers, featuring AI-powered fish detection that interprets raw scan data in real time.

Connectivity Features of the Deeper Range Extender
The Deeper Range Extender is designed to enhance the connectivity between your phone and Deeper sonar devices, extending the Wi-Fi connection up to 200 m (656 ft). This allows users to maintain a stable connection, crucial for accessing real-time data from their fish finders without interruptions, especially from a distance.
The Range Extender is user-friendly, requiring no complicated setup, and it charges completely in just 3 hours. With a battery life of up to 14 hours, it ensures that the connection remains robust throughout your fishing trip. This functionality is particularly beneficial for anglers who rely on consistent connectivity to monitor and adapt their fishing strategies.
User Experience with the Deeper CHIRP+ 4
The user experience with the Deeper CHIRP+ 4 is enhanced by its Fish Deeper app, which allows users to explore depth maps, spot underwater ridges and drop-offs, and track live scans. This app integration provides valuable insights into where fish are holding, enabling anglers to make informed decisions about their fishing tactics.
Additionally, the CHIRP+ 4 allows users to create detailed personal maps by selecting between depth, hardness, and weed information in both 2D and 3D formats.
