NDS Build-in Sonar kit

Upgrade Program for Existing BB2 Users

The NDS Built-in Fish Finder Kit seamlessly integrates with Bait Boat V2/V3/V4, enabling unified control of both the boat and sonar via the NDS FISH FINDER APP. For instance, you can use the boat's Mapping feature to scan areas and automatically generate contour maps; or effortlessly set spots based on sonar readings. All of which significantly enhances your fishing experience.

To ensure installation quality, we have strictly selected following NDS-authorized installation centers.


Pre-order customers will enjoy the following benefits:

1. A Free internal service on their boat and additional one-year extended warranty applied from date of installation.

2. A Choice of a  50% discount on the Autopilot purchase or  a free NDS WiFi extender NDS4

3. Limited availability—only available tothe first 50 customers.

4. Exclusive Upgrade Bundle Price: NDS Built-in Sonar Kit (£499)+Installation Cost (£100)+Free Return Shipping (One-way shipping for BB2 customers)

Depth Scanning

Paired with NDS Sonar, it offers triple-beam frequencies (680kHz, 200kHz, 100kHz). 680kHz ensures high-precision scanning in shallow water(0.3m), while 100kHz/200kHz optimise deep-water (30m) performance.

Sensitivity Control & Clutter Filtering

Sensitivity Control & Clutter Filtering

The NDS Fish Finder APP processes incoming sonar returns with advanced clutter filtering.

Understanding Sensitivity:

· Lower Sensitivity Values: Preserve more detail (less filtering).

· Higher Sensitivity Values: Apply more filtering, resulting in a cleaner display.

Setting Your Sensitivity:

You can adjust the sensitivity level based on your personal preference and experience.

Our Recommended Approach:

· Start Low: Begin with a relatively low sensitivity setting.

· Increase Gradually: Slowly raise the value.

· Find the Sweet Spot: Stop when the display is readable (low clutter) but still shows good detail in the sonar returns.

As your experience grows, mastering this feature will significantly enhance your ability to locate fish and identify underwater structures.

NDS "2nd Returns"

A hard bottom produces an extremely powerful sonar signal. This intense return can sometimes reflect off the water's surface back down, striking the bottom a second time and creating a secondary echo.

· On Your Display: Look for a distinct, parallel line appearing below the primary bottom contour – this is the '2nd return'.

· Why It Matters: Spotting a 2nd return is a reliable indicator of a hard bottom.

· A Mark of Technical Excellence: The clear visibility of 2nd returns is a direct testament to the sonar's superior hardware performance. Our technology achieves this by enabling the transducer to deliver maximum peak power within the smallest form factor and at minimal power consumption. Combined with an optimise amplification circuitry that provides exceptional signal gain while effectively rejecting clutter, these 2nd returns become strikingly clear.

· The Performance Benchmark: Under identical bottom conditions, the clarity and presence of the 2nd return serve as definitive, hard evidence of the sonar system's overall performance capability.
