Drop & Tow Camera Systems
Save Time. Start Surveying.
Get the clarity, capability, and control you need to capture high-quality underwater imagery, simplify deployments, and reduce the time spent processing survey data.
Capture Better Data
Rayfin Coastal captures high-resolution imagery while embedding metadata such as altitude, depth, GPS, and time directly into your images and videos.
Deploy Faster
Field-tested Drop and Tow frames arrive ready to deploy, removing weeks of custom design and integration.
Operate From One Interface
Control cameras, lights, and lasers, tag events, and automate data logging in DVR+.
Finish Projects Faster
ReviewStudio streamlines post-dive review, event editing, data validation, and structured log exports.
Reduce post-processing time by 50% or more
Find the Right System For Your Survey
Fast deployment. Minimal complexity.
A simple system for deployment from small vessels, delivering high-quality imaging during vertical drops and drifting surveys.
Because the system makes zero seafloor contact, it is particularly well suited to marine protected areas, coral reefs, and environmental impact assessments.
Key details
Up to 400m operation
Rugged aluminum drop frame with stabilization tail
27.5 kg in air; optional weight plates available
Rayfin Coastal HD/4K camera
Depth, altitude, GPS, time, tilt, roll, and temperature data
Smooth video across large survey areas.
Designed for deployment from vessels with an A-frame, the Tow Camera System delivers continuous high-quality imaging along transects.
Its passive altitude control makes it ideal for seafloor mapping, fisheries research, and repeat surveys.
Key details
Up to 380m operation
Passive altitude-control tow frame
Rayfin Coastal HD/4K camera
Continuous imaging for efficient large-area surveys
Depth, altitude, GPS, time, tilt, roll, and temperature data
Capability: Drop & Tow Camera Systems Make Deployment Easy
Skip the build with our field-tested frames that eliminate weeks of design and integration. These ready-to-deploy frames allow teams to mobilize faster, ensuring you spend less time collecting the data your research depends on.
Clarity Starts With Rayfin
The Rayfin Coastal Camera delivers high-quality imaging for subsea drop and tow applications, utilizing scratch-resistant, water-corrected LiquidOptics™ and Rapid Digital Imaging (RDI) for continuous, sharp stills in harsh environments. Our Rayfin cameras embed altitude, depth, GPS, and time metadata directly into images and videos, ensuring data alignment. This has proven to cut post-processing time by 50% or more.
Control: One Software, Every System
With DVR+, you can control your camera, lights, and lasers, tag events live, and automate data logging with timestamps - all from a single interface. This streamlined software increases ease of use, enabling faster completion of projects.
Capture 12.3 MegaPixel Images with SubC Rayfin Cameras and get accurate measurements with SubC Parallel Line Lasers.
What Our Customers Are Saying
“Rayfin has been a game-changer for Ocean Ecology's teams, cutting our post-survey processing times by at least half, and even more for larger projects. The efficiency it offers is unparalleled, making it an invaluable tool for our survey operations.”
Ashley Kirby,
Head of Survey
“We're very happy with the image quality, especially in very dark environments. The Ethernet feature is a big time and money saver for us because we can download still images in real-time. The other great thing about SubC is that they are very collaborative.”
Dr. Friedrich Abegg,
ROV-Team Leitung
“We've been impressed with the software's capabilities. Features like the visual EXIF GPS indicator are incredibly helpful. The collaborative approach has truly enhanced our project workflow and it's great to have such a responsive and supportive partner in SubC Imaging.”
Katie Duncan,
Project Environmental Scientist
