Side Scan Sonar and Sub Bottom profiler.
Now add true dual channel side scan and Sub Bottom profile to your hydrographic surveys.
Ross Laboratories, well known for its line of multi channel sweep systems, has developed a low cost, series of side scan sonar and sub bottom profiler systems designed for hydrographic surveyors.
Three versions allow users to configure a system that meets their survey
requirements. Use either well known Chesapeake Technology’s Sonar
Wiz.map™ software for a complete system, or the Hypack™ side
scan module for adding true side scan to your hydro survey capability.
Also compatible with Isis™ data collection systems.
Model 4901 -Complete
system in splash tight case with 12 inch
sunlight readable LCD display.
Model 4910 -Add on
option for the Ross Model 960 Surveyor, adds
side scan capability to the 960’s complete survey
system in one case design.
Model 4920 -Isis™ replacement sonar module. Towfish, transceiver, and control panel, designed to work with the Isis™ topside data collection system.
4900 Transceiver unit: 425kHz Side Scan, 3.5 or 7kHz Sub Bottom:
General:
The sub bottom profiler module of the 4900 series, can be used independently or together with the side scan features of the system. The 4900 series is a modular system that can be configured with either one or both functions installed. At a later date it is a simple factory upgrade consisting of installing the appropriate transceiver printed circuit boards and configuring the software to add the missing feature. Of course the additional transducer(s) will also be required.Connectors:
Display interconnect.
Side Scan transducer
Sub bottom transducers One or two depending on configuration.
Controls: External: None
Internal:
Side Scan Int. TVG On /Off, Int. TVG level and curve.
3.5 or 7Khz sub bottom selection.
Sub bottom envelope or detected output.
Power: Supplied from display unit.
Dimensions: 17.5L x 15W x 7H.
Weight: 17lbs.
Transceiver: |
|
| Frequency: | 3.5Khz or 7.0khz single frequency, switch selectable with purchase of second transceiver PCB. |
| Transmit Power: | 1500 watts rms. |
| Pulse width: | Switch selectable .2, .5, 1.0ms |
| Receiver: | Plug in single frequency PCB. 3.5 or 7 kHz. No TVG or AGC. |
| Gain control: | Rotary knob. 10 position, even steps. |
| Output signal: | Envelope or detected signal, switch selectable. |
| Transducer: | |
| Frequency: | 3.5 or 7.0 Khz. |
| Beam angle: | 80 degree conical at -3db. |
| Operating depth: | 2000 feet maximum. |
| Configuration: | System can be user configured for single or dual transducer operation. Dual transducers offer a significant increase in shallow water performance. One transducer is used for transmit, one receive, eliminating some of transducer “ringout” inherit at these frequencies. |
| Mounting: | On small boats in calm water, over the side pole mounting is standard. Consult the factory for optional mounting configurations for use in offshore, deepwater applications. |

Side Scan / Sub Bottom System
Lightweight suitcase design with a small tow fish makes an ideal carry on system for remote fly in destinations reducing the costs of shipping and set up of conventional systems.
- Two compact splashtight cases (show above), one containing the display and user controls, the other transmitter and receiver cards for both side scan and sub bottom channels.
- A portable two unit design with a 12 inch sunlight readable display for use in small open boats.
- The 4901 display module can also be used as a portable data collector with its multiple I/O ports.
- Compact lightweight towfish allows for easy one man manual deployment and retrieval.
- Towfish contains only transducer arrays. No expensive electronics package to flood or loose.
