Ultra High-Definition Imaging That Drives Smarter Decisions

ClearVü and SideVü UHD: A Tactical Advantage Below the Surface

Underwater interpretation has been fundamentally improved through Garmin’s Ultra High-Definition sonar imaging. Instead of abstract arches and guesswork, photo-like visuals are delivered with remarkable consistency.

Because structure, bait, and fish can be distinguished instantly, time on the water is used more effectively. Consequently, less effort is spent repositioning, while more attention is focused on strategy.

Benefits of UHD Sonar Imaging:

• Submerged structure is revealed with exceptional detail

• Fish positioning is identified with greater confidence

• Bottom composition changes are interpreted more accurately

• Search patterns are completed faster and more efficiently

Through this level of visual clarity, decision-making is simplified—even in unfamiliar waters.

---

Traditional CHIRP Sonar for Reliable Target Separation

Consistency That Builds Trust Over Time

While ultra-clear imaging enhances exploration, traditional CHIRP sonar ensures reliability. By transmitting a continuous range of frequencies, clearer returns are generated across varying depths and conditions.

As a result, fish targets are separated cleanly from structure and clutter. This consistency builds trust in the data being displayed, especially during high-pressure fishing situations.

Because dependable information reduces uncertainty, confidence grows with every use.

---

Seamless Networking for Shared Intelligence

Built-In Connectivity That Expands Capability

Fishing rarely happens in isolation. Therefore, the ECHOMAP Ultra 2 166sv has been designed to integrate seamlessly with compatible Garmin devices. Sonar data, waypoints, and maps can be shared effortlessly, allowing everyone on board to stay aligned.

Instead of working independently, crews can collaborate using synchronized information. Consequently, efficiency is increased and miscommunication is reduced.

Networking Highlights:

• Waypoints can be shared across compatible units

• Sonar data can be viewed from multiple displays

• System expansion is supported as needs grow

Through shared intelligence, the entire experience becomes more inclusive and cohesive.

---

Customizable Interface Designed for All Users

Personalization Without Complexity

No two anglers fish the same way. Because of this, the interface has been designed to adapt to individual preferences. Views can be customized, data fields can be rearranged, and frequently used functions can be accessed quickly.

Rather than forcing a fixed workflow, flexibility is provided. Therefore, users of all experience levels feel supported rather than restricted.

Importantly, these customizations enhance usability without increasing learning curves—ensuring accessibility remains central.

---

Chartplotter Intelligence That Supports Strategic Planning

Mapping Tools That Evolve With You

Navigation is not treated as an afterthought. Instead, chartplotting has been elevated into a strategic tool that supports long-term success. Depth contours, shoreline detail, and waypoint management are all integrated into a single, intuitive system.

Because fishing knowledge accumulates over time, saved data becomes increasingly valuable. Each trip builds upon the last, creating a personalized map of success.

Strategic Chartplotter Advantages:

• Hotspots can be marked and revisited easily

• Routes can be planned and adjusted confidently

• Waterways can be explored safely and efficiently

Through intelligent mapping, preparation becomes proactive rather than reactive.
