In carp fishing, knowing the water is half the battle. A decent sonar on a baitboat gives you the lake bathymetry in one session. But if that information dies on the SD card, you start from scratch every season. Horizon Sonar stores every recording in the cloud so five years later you still know where to put the bait.
Anglers who've spent years on the same venue know it. Some zones produce, some don't, sometimes separated by just a few metres. The trick is knowing which is which — and being able to come back when the conditions are right.
One pass with the baitboat draws complete bathymetry: drops, ledges, weed. What a local learns in years.
Exact GPS pin where a carp shows up on the viewer. Depth, time of day and water temp recorded. Next session you go straight to it.
Compare the same bank in April, May and October. Patterns invisible in real-time become obvious: where the carp are each season.
Fishing in a group: forward the recording link on WhatsApp and both see the same bathymetry. No USB sticks, no heavy email attachments.
Horizon sonars (Spectra, Crystal, Mirror) integrate with Navigator baitboats and compatible third-party hulls. Plug & play.
The moment the boat moves, the sonar records to its SD. You fish; it logs every ping with GPS, depth, temperature and echoes.
Back home, plug the SD into your computer and drag the recording onto the browser. Archived in seconds, accessible everywhere.
For medium waters (gravel pits, small reservoirs), Horizon Spectra is plenty, with GPS and bathymetry. For big lakes with weed, Crystal gives sharper bottom rendering. Mirror is for intense sessions where you want to see left and right of the baitboat, not just below.
Yes, but you lose half the value. Horizon sonars are designed for baitboats and controlled sweeps across the lake. Kayaks work; from the bank you lose the GPS sweep that creates most of the value.
Three practical reasons: (1) SD cards get lost, fail or get accidentally reformatted; (2) home computers aren't eternal either; (3) cloud lets you review the lake from your phone during the session, not just after.
Yes. The bathymetry you build session after session stays linked to your account. The more you fish the same venue, the more detailed the map gets.
