Incorporating many of the features available on larger echo sounders, the CEEPULSE™ is CEE HydroSystems’ entry-level black box 200 kHz echo sounder designed for shallow water surveying. With soundings collected at up to 10 Hz using a standard or narrow beam survey grade transducer, bathymetry results are developed with a high degree of confidence.


The CEEPULSE™ can output soundings at up to 10 Hz, giving dense bottom coverage for the most trustworthy survey results available from a “black box” echo sounder. With some design elements shared with the advanced CEESCOPE™ echo sounder, the CEEPULSE™ robust bottom-tracking algorithm offers reliable and repeatable results where other similar echo sounders cannot. Compared to basic units operating at 1-2 Hz, the CEEPULSE™ requires far less compromise in data quality to obtain a simple bathymetry survey solution.

CEE HydroSystems’ CEE CONNECT software offers a modern and intuitive way to communicate and configure the CEEPULSE™ echo sounder, making it simple to start collecting data. Simply establish a Bluetooth connection. Data are transmitted to a survey computer for acquisition using hydrographic software such as HYPACK®, QPS QINSy, Trimble HYDROPro, or Eye4Software Hydromagic. Data may also be directly transferred using the Bluetooth port to a hand held data collector such as the Trimble TSC2 or TSC3 for incorporation into a point measurements data file.

Using the same professional quality hydrographic survey transducers as used with full-size echo sounder systems, the CEEPULSE™ offers a true 0.3 – 100m (1 – 328ft) depth capability and 1cm resolution. With exceptional shallow water performance, the CEEPULSE™ is ideal for small boat inland water surveys.


The CEEPULSE™ offers trouble-free sounding data in shallow water, even as little as 30cm (12″). While some inexpensive single beam echo sounders claim to be able to provide bottom tracking in very shallow water, the CEEPULSE™ actually delivers.

The CEEPULSE™ may be interfaced with a hand-held data collector such as the Trimble TSC2 or TSC3 typically used for land surveying with a GNSS receiver. For small-scale hydrographic surveys the depth output of the CEEPULSE™ may be recorded by the data collector using software such as Trimble Access or Carlson. The depth value from the CEEPULSE™ at the time of each GNSS point shot is subtracted from the antenna elevation to give a bottom elevation and position. The CEEPULSE™ is simply paired and connected to a Bluetooth port of the data collector and configured as a “Depth Sounder”, offering a straightforward and precise way to collect soundings without using any external PC or hydrographic software.

This step-by-step guide HERE shows you how to acquire CEEPULSE™ data using a Trimble TSC3 data collector. The depth output from the echo sounder may be easily incorporated into GNSS shots as a peripheral measurement and real time fully corrected bottom elevation may be recorded in the Trimble data file.

– How tough is the CEEPULSE™?

With a thick shell and components exceptionally well secured, the CEEPULSE™ is hard to damage.

– What is the maximum depth achievable?

100m with 200 kHz transducer.

– How do I connect the CEEPULSE™?

The transducer and power / data connections are the same as all other CEE HydroSystems echo sounders. The Y power / data cable terminates in a standard serial DB9 connector and a pigtail power cable.

– How is it powered?

Use any 12-24V DV supply.

– What is the data output?

The CEEPULSE™ can output common formats data such as DESO25, Odom SBT, NMEA0183.

– How is the echo sounder operated?

Power up and the sounder immediately starts pinging, with a power and data LED flashing once per ping.

– Do I need an acquisition PC?

Yes. The CEEPULSE™ does not log data.

– Is there a Bluetooth data output?

Yes. Input and output. The CEEPULSE™ can output Bluetooth data to a PC, tablet, or field data collector. To change the CEEPULSE™ settings, simply establish a Bluetooth connection and open the CEEPULSE CONNECT software portal.

– Can I change the echo sounder sonar settings if needed?

Yes. Using the CEEPULSE CONNECT software portal and RS232 cable or Bluetooth connection. Maximum depth, blanking distance, gain, pulse width, and detection threshold may be manually adjusted.

– Can I enter sound velocity (SV)?

Yes. This is entered using the software portal.

– Can I use my existing transducer?

Maybe. We can supply patch cables for some connector types.

– Can the CEEPULSE™ take in GPS?

No. The CEEPULSE™ is a standalone echo sounder.
