– Where do I connect my GPS?
We recommend GPS data are fed directly into the CEE ECHO™. This allows all data to be time stamped, saved, and output in a single highly accurate data stream with minimum latency.
– Can I use RTK GPS?
Yes. RTK can be used with the CEE ECHO™ to generate a bottom elevation point cloud in the hydrographic survey software, consistent with the local grid coordinates and vertical datum.
– How long does the battery last?
The rechargeable battery will last 8 hours in operation, although this can be extended by turning off the touch screen display when not required.
– How long does it take to recharge the battery?
The battery will recharge in 4 hours. The battery will NOT recharge unless the unit is powered off.
– Can an external power source be used?
Yes. Any 12-24V supply may be used.
– What is the maximum depth achievable?
100m is the limit for both 33 kHz and 200 kHz transducers. The CEE ECHO™ is designed to output soundings of high quality in shallow water.
– Can I use my own existing transducer, eg Odom?
Yes. We can supply patch cables for third party transducers with Amphenol connectors.
– How is the transducer mounted?
The transducers can each be supplied with a matching mount that will fit standard 50mm OD pipe. The transducer cable is passed up the inside of the pipe to prevent damage
– Can I use 24 kHz or 28 kHz transducers?
Yes. The CEE ECHO™ is designed for transducers at 24 kHz or 33 kHz.
– How waterproof is the unit?
A special custom manufactured lid seal is used to ensure water cannot penetrate through the box and the seal will remain intact after years of use. Waterproof rugged LEMO cable connectors are used.
– Do I need an acquisition computer?
No. While the CEE ECHO™ is often used with a laptop collecting the data in real time, it has internal memory allowing collection of all data with no connected PC. This also serves as a useful backup data log.
– Can I use a hand held data collector, such as Trimble TSC2 or TSC3?
Yes. The Bluetooth data output from the CEE ECHO™ may be accepted by land survey data collectors after pairing the devices. Depth measurements from the CEE ECHO™ may then be stored in a point data file with GPS data.
– How do I take data off the CEE ECHO™?
Inserting a USB flash drive into the USB port will cause data to be automatically copied onto the external USB.
– How do I change the units’ settings?
All the settings are available through the touch screen display with a simple on-screen menu system. A computer is not required to change any of the CEE ECHO™ settings, however the CEESCOPE CONNECT software utility allows settings to be changed through a connected PC.
– Can I change the echo sounder sonar settings?
Yes. The high and low frequency channels can be independently adjusted in terns of pulse width, gain, detection threshold, blanking distance, and maximum depth to follow the desired bottom surface.
– How do I conduct a bar check?
The CEE ECHO™ has a special bar check routine to make it easy to conduct a calibration check. A connected PC is not required to complete this procedure.
– Can I adjust sound velocity (SV)?
Yes. Enter the SV value directly into the CEE ECHO™, or input the temperature and salinity and the SV will be calculated.
– What are the output formats?
The CEE ECHO™ outputs a proprietary output format including GPS position, sounding depths, and a full water column echogram binary packet file in a time-stamped data stream. Other industry standard formats may be selected such as DESO25, Odom SBT / DBT, NMEA0183.
– What software package is required?
The CEE ECHO™ will work with all available hydrographic acquisition packages. The package used must contain a driver for the CEE HydroSystems digital echogram to be able to see the water column envelope. HYPACK® is the most suitable option.
– Where do I mount the transducer?
The transducer ideally should be mounted half way between bow and stern to minimize motion from waves, and should be braced with ropes fore and aft to prevent movement in the water. The minimum draft should be 50cm from the water surface to the transducer face, or slightly above the keel depth.
– What is the typical survey speed?
Usually 4-6kts. Surveying at over 8 kts may cause issues with air bubble entrainment.
– Can I mark points of interest / events?
Yes. The “event” button creates a sequential event number in the data record, associated with the exact position and depth when the button is pressed.
– Can I use the CEE ECHO™ with an ADCP?
Yes. The GPS and/or depth data may be routed to an acoustic Doppler current profiler such as the Teledyne RD Instruments River Ray, River Pro, and Rio Grande to collect simultaneous velocity measurements.
