Modern fishing sonars record kilometres of data every session: bathymetry, fish echoes, water temperature, GPS trail. Horizon Sonar ships that data to the cloud the moment you get home, archives it, lets you revisit it from any device, and share the spot that produced with a single link.
A fishing sonar tells you what's underneath in real time. But once the recording sits forgotten on the SD card and gets overwritten, that knowledge is gone. Horizon Sonar fixes that.
Each session adds detail to the lake bathymetry. After three sessions you know the venue better than most locals.
When a 12 kg carp shows up on the viewer, it's pinned to an exact GPS, depth and timestamp. Next time you go straight to it.
Drag the recording onto the browser, done. No software to install, no SD card to lose, no hard drive that fills up.
Send a WhatsApp link. The recipient sees your recording in their browser, no account needed. Or sell it on the marketplace.
Every Horizon sonar (Spectra, Crystal, Mirror) records automatically in our format. The file stays on the SD until you get home.
Open horizon.nuntius.club, drag the recording onto the browser and the system processes it. Nothing to install.
Web viewer with bathymetry, GPS trail, fish echoes, temperature. Filter by lake, date, depth. Share or sell what you want.
A fishing sonar (fishfinder) is a transducer that fires ultrasonic pulses underwater and measures the echo. The return time becomes distance; the device draws depth, fish, vegetation and thermoclines on screen.
In carp fishing the sonar lives on a baitboat or kayak — the boat sweeps the lake and the sonar logs every ping with GPS.
All Horizon sonars (Spectra, Crystal, Mirror) record in sonar recording. A compact format designed to fit many hours of pinging without filling drives. Each row carries timestamp, GPS, depth, water temp and detected echoes.

Yes. Each recording has an optional public link. The visitor sees bathymetry and GPS trail from their browser, no signup needed. You pick which recordings are public and which stay private.
The app that ships with the sonar is built for live viewing while you fish. Horizon is the archive of your entire season — re-open last year's sessions, compare the same bank in April vs September, never rely on an SD card or local disk again.
30 days free, no card. €2/month or €19.99/year afterwards. If your sonar records sonar data, it's ready for Horizon.
