SonarDepthPro

Windows desktop application

Your sonar wrote a file. Now read it.

Marine chartplotters, like the Garmin® ECHOMAP™ series, can record your scans as .rsd files but give you no built-in way to review them. With no official desktop software available to read them either, your recorded data is effectively locked. SonarDepthPro takes those unreadable files and opens them on your Windows computer.

What it does

Reads RSD recordings

Point it at the recordings from your sonar unit's memory card and the trace opens on screen. No conversion step, no manufacturer software required.

Review at your own pace

Scroll back through a whole trip, stop on anything interesting, and look at it on a screen larger than the one bolted to the boat.

Measure what you see

Read depth off the trace and inspect the returns properly, instead of squinting at a five inch display in daylight.

Licensed to you

One purchase, one license key, activated inside the application. Your key stays valid for the version you bought.

Who it is for

Anglers, boat owners and anyone else who records sonar and wants to look at it afterwards. If you have ever finished a day on the water thinking there was something on the screen you did not have time to study, this is the tool for that.

SonarDepthPro runs on Windows. It reads your own recordings from your own equipment and does not require an account or an internet connection to work, beyond the one-time license activation.

Frequently asked questions

What are the system requirements for SonarDepthPro?

  • Operating system: Windows 11, certified Windows 11 hardware
  • Memory: 8 GB minimum (16 GB recommended)

Why does Windows show a warning when I start the installation?

Windows 11: “Smart App Control” may block the installer

SonarDepthPro is not yet code-signed with a commercial certificate. On Windows 11 machines where Smart App Control is active, Windows may refuse to start the program. This is not a fault in the program or in your sonar files, Windows is blocking any application it does not yet recognise.

To allow SonarDepthPro to run:

  1. Open Windows Security
  2. Go to App & browser control
  3. Open Smart App Control settings
  4. Set Smart App Control to Off
  5. Run the installer again

Most computers already have Smart App Control switched off, in which case you will never see this message. If the setting is not shown at all, it is not active on your machine and something else is the cause, please get in touch.

The warning does not mean the file is unsafe. It only means the publisher has not paid to be pre-verified. To continue, click More info and then Run anyway. Only ever install the file you downloaded from the link in your purchase or trial email, and if anything looks wrong, email support@visionframe.se before you run it.

Do I need an internet connection to use SonarDepthPro?

No. You only need to be online once to activate your license key. After that, the software runs completely offline on your Windows machine. Your sonar data stays on your computer and is never uploaded anywhere.

Will SonarDepthPro always be able to read my recordings?

SonarDepthPro is built to read the .rsd files generated by current and past Garmin® units. However, because this is a proprietary file format, Garmin could technically change how they encode these files in a future firmware update.

If they do, I will do my best to figure out the changes and update SonarDepthPro. But since VisionFrame is completely independent and receives no technical specifications from the manufacturer, I cannot guarantee that future device updates won’t break compatibility. You are buying a tool that works with the files your equipment produces today.

Are updates included in the price?

Yes. Your one-time purchase includes all minor updates and bug fixes for the current major version. If Garmin makes small changes that I can patch, that update will be free. There are no subscriptions and no hidden fees.

Why is SonarDepthPro a paid tool rather than free open source?

While SonarDepthPro builds upon public reverse-engineering research and open-source parsing techniques, turning raw data streams into a fast, stable desktop application with full visual rendering, measurement tools, and a clean interface takes hundreds of hours of specialized work.

Charging a fair, one-time price allows VisionFrame to remain independent:

  • Personal support: When you have a question or an issue, you get direct help from the developer who wrote the code.
  • Ongoing maintenance: It funds continuous bug fixes, performance improvements, and support for newer Windows updates.
  • No hidden catches: Because you pay upfront, the software doesn’t need to track you, show ads, force online accounts, or lock you into recurring subscriptions.

You are paying for a complete, maintained, and reliable tool—not just raw code.

Can I use this software to navigate?

Absolutely not. SonarDepthPro is designed exclusively for viewing and reviewing sonar data after you have safely returned to shore. It is not a navigation system, and the depth estimates on screen must never be used for hazard avoidance.
