Deeper CHIRP+ 4.0 (AI)

Deeper CHIRP+ 4 is a professional-grade castable sonar that combines tri-frequency CHIRP technology, artificial intelligence, and ultra-precise mapping. It is designed for anglers who demand maximum accuracy, better fish detection, and a complete understanding of underwater structure.

Advanced AI Fish Detection

Built-in artificial intelligence analyzes sonar data in real time, identifying fish based on their shape and movement. Fish are displayed only after full detection, reducing false signals and improving reliability.

Tri-frequency CHIRP Sonar

• 100 kHz (wide beam ~47°) – for fast area scanning
• 240 kHz (medium beam ~20°) – balanced detail and coverage
• 675 kHz (narrow beam ~7°) – maximum detail and precision
• Scanning rate up to 15 scans per second
• Target separation up to 1 cm

Full Mapping Capabilities (2D & 3D)

Create detailed maps of your fishing spots and store the best locations:

• Bathymetric (depth) maps
• Bottom hardness maps
• Vegetation maps
• Fish location marking (hotspots)
• Real-time mapping in the mobile app

High-Precision GNSS Positioning

• GPS
• GLONASS
• Galileo
• BeiDou

Multi-system satellite support ensures maximum accuracy for mapping and navigation.
