Next Generation pole-mounted echo sounder.

CEE-LINE™ brings hydrographic-grade performance to bathymetry projects using land survey data acquisition. Indestructible with exceptional sounding consistency, simply connect the CEE-LINE™ to a data collector, tablet or PC for accurate and trustworthy results.



The CEE-LINE™ represents a next generation approach to GNSS pole-mounted bathymetry surveys. With an indestructible construction and a no-nonsense USB power cable connection to the acquisition data collector, tablet or PC the CEE-LINE™ is a survey-grade echo sounder designed for maximum reliability and exceptional bottom tracking. With no internal battery to worry about, the CEE-LINE™ is always ready to start surveying.

Containing a super-fast modern processor running advanced bottom tracking algorithms, the CEE LINE™ keeps a solid lock on the bottom even in extremely shallow water. With a ping rate up to 10Hz and two frequency channels 33 kHz and 200 kHz available, the CEE LINE™ may equally be used with dedicated hydrographic acquisition software or with GNSS topographic acquisition utilities.


Ultra-Modern Processing Unit

The CEE-LINE™ echo sounder uses a 2016 generation small form factor processor to run complex bottom tracking algorithms while maintaining a high ping rate, maintaining a rock-steady lock on the “real” bottom and ignoring fake signals such as double reflections and unwanted noise. With flexibility to use several different transducers and even operate in dual frequency 33/200 kHz mode, the CEE-LINE™ is a true hydrographic survey quality performer whether used with a GNSS data collector or with an acquisition PC running HYPACK®.


Hydrographic Quality Narrow Beamwidth Transducers

All CEE echo sounders use hydrographic survey-grade analog transducers, including the CEE-LINE™. This means the depth sounder calculations are performed in the CEE-LINE™ processor module and not in the transducer itself as happens in so called “smart” echo sounders.


Flexible Solution for All Data Acquisition Methods

The CEE-LINE™ is designed to operate with hand controllers using either a USB or COM port interface. Simply plug the data / power cable into the acquisition device and bring in the echo sounder depth data. The CEE-LINE™ outputs several formats for trouble-free integration into GNSS continuous topo data recording.

The CEE-LINE™ can be used with practically all GNSS data collection equipment. Whether you are replacing an existing pole-mounted echo sounder or introducing a new hydrographic capability for inshore bathymetric surveys, the CEE-LINE™ can be trusted to work seamlessly with common acquisition utilities such as Trimble Survey Controller, Trimble Access, Carlson SurvCE, Topcon MAGNET Field, and Leica Viva. The CEE-LINE™ continuously streams accurate depth data every tenth of a second, ready to be incorporated into the GNSS topographic dataset as a modified point elevation.


The USB smart cable offers a simple and reliable data and power interface with the CEE-LINE™. No need to worry about charging batteries or dealing with potentially troublesome Bluetooth interface settings, or having to use a potentially unreliable wireless connection. Every time the CEE-LINE™ is plugged in, it is ready to start work. With a low power draw – especially working in shallow water – battery run time on a connected data collector will not decrease excessively even with the acquisition device powering the CEE-LINE™.


Rugged and Durable

Manufactured to exceptional quality standards with an encapsulated processor core and an over-molded jacket the CEE-LINE™ will withstand years of field work.  Don’t introduce a weak link in your survey equipment – choose the CEE-LINE­™.

Minimalist Design

By reducing the connections to just two waterproof LEMO plugs (transducer, and power / data) the CEE-LINE™ has no weak points, less to go wrong, and nothing to break off.




200 kHz CEE-LINE Echo Sounder

The CEE-LINE™ echo sounder is supplied with a USB power / data cable compatible with a PC, tablet, or data collector. Two transducer options are available separately – 3 degree narrow beamwidth or 9 degree standard beamwidth.

The optional RS232 DB9 cable with a flying lead for DC or USB power allows the CEE-LINE™ to connect using a standard COM port interface.

NOTE: Previous generation CEEDUCER™ and CEEDUCER PRO™ transducers are not compatible with the CEE-LINE™.



33/200 kHz Dual Frequency CEE-LINE Echo Sounder

The CEE-LINE™ is available as a two-channel echo sounder that may be used for surveying in regions with poorly consolidated or disturbed sediment where a 200 kHz-only echo sounder might be inadequate. Using the compact M195 transducer,the CEE-LINE™ offers a lightweight and portable dual frequency system. The CEE-LINE™ advanced power management automatically adjusts the ping rate to ensure enough ping energy is available to track the bottom. Existing 200 kHz-only units may be upgraded to dual frequency with a simple field firmware update.


CEE-LINE Surveying Kit

For convenient installation on small boats, the 200 kHz CEE-LINE™ echo sounder is available in a surveying kit with custom brackets and mounting hardware. Everything needed to start hydrographic surveys with a data collector, tablet, or PC is included in the waterproof Pelican 1560 roller case. See the CEE-LINE KIT kit tab in the product information table below for details.

Data Collector TSC2 / TSC3 / TSC7 or Tablet

Several data output formats are available on the CEE-LINE™ allowing depth data to be brought into GNSS measurement software to record a final bottom elevation. Well-established Trimble configuration options are easily added to the data collector in order to start work with the CEE-LINE™. The USB port or DB9 COM port may be used as desired, with the CEE HydroSystems “Smart USB” cable handling data and power in one for field tablets. Using a field tablet PC further enhances the bathymetric data collection process using the CEE-LINE™, enabling the simultaneous CEE-LINE CONNECT software to fine-tune the echo sounder sonic characteristics. For data collectors, a split USB / COM cable is used.

Connection to TSC2, TSC3 or TSC7 Data Collectors

The split USB / RS232 cable is used to supply power to the CEE-LINE™ from the data collector and to allow the echo sounder data to be accessed through the standard COM port.

CS35 Tablet

The CEE-LINE™ output may be configured to interface with the Leica CS35 tablet using Captivate software. Power for the CEE-LINE™ is provided by the 5V USB cable.

Connection to CS35 Tablet

The Smart USB cable may be used when connecting the CEE-LINE™ to a tablet PC running a full Windows operating system. The USB port provides the 5V power to the echo sounder and generates a virtual COM port that may be accessed by the acquisition software.

CS15 / 20 Data Collectors

The CEE-LINE™ output may be configured to interface with the Leica CS15 and CS20 data collectors using Viva or Captivate software. The data connection may be through the LEMO or 9 pin COM port as fitted.

Connection to CS15 / 20 Data Collectors

For data collectors that do not output 5V on the USB port, a separate rechargeable USB power pack can be used with the CEE-LINE™.

Data Collector FC500 or FC5000 Tablet

The CEE-LINE™ may be used with Topcon data collectors running MAGNET Field. Power for the CEE-LINE™ is provided by the 5V USB port, and echo sounding data is passed through the standard COM port over a split USB / 9 pin serial cable or through the standard Smart USB cable.

Connection to Topcon Data Collectors and FC5000 Tablet

There are two cable options available for the echo sounder interface to Topcon devices. A split “Y” cable with a generic 9 pin DB9 female and standard USB connector may be used, with power supplied by the data collector’s USB port. Alternatively, for tablet PCs running a full Windows operating system, the Smart USB cable may be used instead. This cable automatically generates a COM port when plugged into the device, allowing both power and data to be passed over a single USB cable. Use of the Smart USB cable eliminates the requirement for a physical 9 pin COM port.

Setup in MAGNET Field

The CEE-LINE™ is added as a peripheral device, with the device interface through the appropriate COM port.  Serial data communication parameters should be set to match the CEE-LINE™ output configuration – usually 9600 baud. The GENERIC NMEA echo sounder model is selected to match the echo sounder output, which should be NMEA $SDDBT or $SDDBS. If DBS (Depth Below Surface) output is selected, the draft entered in the CEE-LINE™ configuration will be incorporated into the depth measurement. If DBT (Depth Below Transducer) is selected, any draft entry will be ignored.

Carlson SurvCE Data Collector Acquisition Software

The CEE-LINE™ echo sounder may be used with Carlson software running on GNSS data collectors for a simplified bathymetry survey approach compared to traditional hydrographic acquisition software. The serial RS232 data output from the echo sounder is treated as a peripheral input, and depth data are automatically applied to measured GNSS elevations to give a resultant underwater bottom elevation.

Learn how to configure the CEE-LINE™ echo sounder and Carlson SurvCE software to allow incorporation of CEE-LINE™ depths into GNSS point elevations.
