Deeper Smart Sonar CHIRP 4+

Deeper Smart Sonar CHIRP 4+

The world's first AI-powered castable fishfinder.

The all-new CHIRP+ 4 with AI-powered sonar data analysis!

The CHIRP+ 4 incorporates artificial intelligence developed by anglers that accurately analyzes sonar returns displayed on your smartphone screen. It reliably determines the nature of echoes—fish, branches, air bubbles, etc.—especially in conditions where interpreting this information is complex.

AI-powered fish detection, personal bottom hardness, and weed maps in 2D & 3D, along with 3-frequency CHIRP technology. The most advanced castable sonar ever made.

AI-Powered Fish Detection

No need to guess what's on your sonar screen. CHIRP+ 4's built-in AI interprets raw scan data in real time, automatically identifying fish from noise, so you can focus on catching, not decoding readings.

AI performance steadily improves with continuous updates.

Fish Locations on Your Maps

With CHIRP+ 4, you’ll see detected fish not only during live scanning but also on your saved maps in both 2D and 3D. View past fish marks anytime.

3D view

Fish icons appear directly on your 3D bathymetric map for spatial awareness.

2D view

Fish icons appear directly on your 2D depth map for spatial awareness

Multi-Layered Personal Maps

Scan the depths and map out the bottom in great detail.

Depth

Create your own detailed personal depth maps that reveal underwater contours and structure, helping you understand every fishing spot.

Hardness

With CHIRP+ 4, you can generate personal bottom hardness maps in both 2D and 3D, revealing exactly where hard gravel transitions into soft mud.

Weeds

CHIRP+ 4 maps aquatic vegetation in detailed 2D and 3D layers, revealing weed edges, pockets, and clear lanes.

Powerful and Variable CHIRP Technology

Choose between 3 beam widths and explore the bottom structure in rarely seen clarity with whichever option suits your needs. Analyze lakebed features/hardness, vegetation, and depth with 100 meter, all in one cast!

4x More Pixels in Shallow Water

4x more pixels means distinguishing features, such as fish, bottom drop-offs, and snags, in depths of up to 5 meter, become significantly easier for any angler.

Pro 2+/CHIRP4+ Comparison

Built-in triple beam system

Choose between 3 beam widths and explore the bottom structure in rarely seen clarity with whichever option suits your needs.

Wide

Covers a wide area, which is perfect for identifying any fish activity.

Frequency 100kHz, 47°

Differences between CHIRP+ 4 and CHIRP+ 3

The Most Advanced Technology

The CHIRP+ 4 incorporates artificial intelligence developed by anglers, which accurately analyzes the sonar data displayed on the smartphone screen. It reliably identifies the nature of echoes—fish, branches, air bubbles, etc.

Automatically identify echoes corresponding to fish and visualize them clearly on the 3D map.

Choose from three beamwidths and explore bottom structure with unparalleled clarity.

Identify the nature of the bottom and aquatic vegetation using your own high-precision sonar data to pinpoint the most productive spots.

Visualize bottom features—structures, depths, topography, and slopes—in 3D with exceptional clarity.

Comes with its interchangeable colored cover

Compatible with DEEPER accessories
