Nothing to charge
The CEE-LINE™ runs off your data collector or tablet / PC, so there’s no battery to charge the night before and no dead unit halfway through a job.

Depths you can trust
Dual frequency and a live echogram show what’s really under the pole; soft mud, sub aquatic vegetation or hard bottom, so you can stand behind every number you deliver.

Shallow river mapping
Keeps a solid lock on the bottom even in very shallow water from 0.2 m at 200 kHz.
Environmental monitoring
See submerged vegetation, debris and soft bottoms on the echogram not just a depth number.
Bridges & construction
Consistent depths near piers and hard, reflective bottoms, straight into the GNSS dataset.
Dredging & sediment
Dual frequency 200 / 33 kHz as standard, for poorly consolidated or disturbed sediment.
Kayak & small boat surveys
Lightweight and pole-mounted, powered from the data collector ideal where no survey boat can launch.
GNSS pole-mounted bathymetry
Works with Trimble Access, Carlson SurvCE, Leica Captivate and Topcon MAGNET Field.

Buying guide
What will you connect it to?
The CEE-LINE™ works with the gear you already carry. What you get depends on the device and the software.
Android data collector
No new software
For example, the Trimble TSC5. Depth is logged with every point in continuous topo. The CEE Bluetooth cable sends depths wirelessly and runs from the collector’s USB-C port.

Going wireless? The CEE Bluetooth cable has the Bluetooth radio built into the cable LEMO at one end, USB-C at the other so the CEE-LINE™ sends depths to any Bluetooth collector while drawing power over USB-C.

Step 3 · Data collector
Which cable do you need?
Select either USB-C or USB-A type cables to supply power and send depths to your data collector. A Bluetooth radio is fully encapsulated inside the USB cable and operates seamlessly with the CEE-LINE™: choose to use either the high-speed wired USB or the Bluetooth data output mode without changing any hardware. Plug into a USB power bank for a roving wireless data collector link. The programming cable connects the CEE-LINE™ to a Windows PC for CEE-LINE Connect 3.

Why 20 Hz matters
The same line, surveyed twice.
Two sounders run the same seabed at the same speed. When depths aren’t time-tagged, each one is logged against the GNSS fix it arrives with — so the charted seabed slides along track. The slower the ping rate, the further it slides.

Offset = speed × (ping interval + output latency). Worst case within the ping cycle, for depth output that isn’t time-tagged — the way most GNSS data collectors log depth. A faster ping rate shrinks the error; the fixed output latency remains. Output latency30 ms
