Supplier's note

  1. Technical Breakthroughs:

    • 1cm Accuracy: Enables centimeter-level bathymetric mapping for engineering projects requiring strict tolerances.
    • Dual Frequency Design: Combines 200kHz (deep-water penetration) and 455kHz (high-resolution shallow zones) for versatile terrain analysis.
    • Ruggedized Materials: The aluminum alloy enclosure withstands saltwater corrosion and mechanical shocks, extending field lifespan.

  2. Version Selection Guidance:

    • Base Model: Ideal for routine surveys in shallow coastal areas where 200m depth suffices.
    • Advanced Model: Preferred by hydrographic agencies needing extended battery life and Wi-Fi for real-time data sharing.
    • Pro Model: Chosen by deep-sea researchers or oil/gas operators requiring 500m depth capability and 4G connectivity for remote operations.

*Pro Model accuracy meets or exceeds IHO S-44 standards for hydrographic charting.

⭐ Customer Reviews and Testimonials

Authentic User Feedback

🔬 Hydrographic Surveyor Reviews

⭐⭐⭐⭐⭐ Captain Elena Rodriguez - Coastal Mapping Team
"We've been using the HY1601 Advanced Model for six months on our survey vessel, and it’s transformed our data collection process. The 1cm accuracy is not marketing fluff—it holds up even in turbid estuaries. The dual-frequency mode lets us switch between deep channels and shallow flats seamlessly. We’ve already caught discrepancies in outdated nautical charts thanks to its precision."

🎣 Recreational Boater Reviews

⭐⭐⭐⭐⭐ James Wilkins - Weekend Angler & Lake Explorer
"I bought the Base Model for my fishing boat, and I’m stunned by how professional-grade it feels. The 7-inch touchscreen is bright and responsive, even under direct sunlight. I use it to map drop-offs and locate submerged structures. It helped me find a new bass hotspot that wasn’t on any public map. Setup was intuitive, and cleaning the transducer after each trip is a breeze with just freshwater."

🌊 Environmental Researcher Reviews

⭐⭐⭐⭐☆ Dr. Amina Patel - Freshwater Ecology Lab
"We deployed the HY1601 Pro Model for a lake sediment study, and the 4G connectivity and 24-hour battery life made remote monitoring possible without constant site visits. Data logging is reliable, and exporting to GIS software took minimal effort. The only reason I’m not giving five stars is that the initial firmware setup required a support call—but once configured, it’s been flawless."

Purchase Date: January 2025 | Usage Period: 5 months

⚓ Marine Contractor Reviews

⭐⭐⭐⭐⭐ Lars Jensen - Underwater Construction Contractor
"This unit replaced two older plastic-encased echo sounders that failed within a year due to saltwater corrosion. The marine-grade aluminum alloy body on the HY1601 shows zero wear after seven months of daily use in the North Sea. Its IP68 rating gives us peace of mind during submersion operations. The real-time depth profile display has improved our positioning accuracy during foundation laying by at least 30%."

Purchase Date: April 2024 | Usage Period: 7 months

🛥️ Small Survey Team Reviews

⭐⭐⭐⭐⭐ Maya Tran - Independent Hydrographic Consultant
"As a solo operator running small-scale river surveys, I needed something portable but precise. The ergonomic handles and lightweight build make it easy to carry from site to site. I paired the Base Model with a handheld GPS, and the data sync works well. The customization guide helped me tweak the frequency for muddy riverbeds. For the price, the performance is exceptional."
