Pinger Sub Bottom Profiler
Pinger is designed specifically for shallow water sub bottom profiling (as shallow as 4m and up to 300m in ideal conditions) and is intended for a simple over the side pole mount installation. The Pinger Wet End includes two separate interchangeable projectors – a low frequency 3.5 kHz projector for hard packed sand bottom and a 15 kHz projector for soft mud sediment sonar profiling – plus a broadband hydrophone receive array. A 200 kHz transducer is also included which provides a reference point as to where the bottom begins. This allows a wide variety of practical applications, including geophysical sediment research, harbour shoreline construction, and hazardous pond pollution monitoring.
Number of Channels: 2
Frequency Range (Channel 1): 3.5 kHz/15 kHz
Frequency Range (Channel 2): 210 kHz
Max Depth: 300m
The Pinger Dry End is a portable, black box system which plugs into the user’s computer via a USB cable connection. The system is controlled through the KNUDSEN SounderSuite Windows application software which is supplied with the unit. The user will be able to view depth records in real time and record high resolution data onto their computer hard drive for archival and post processing.
The Pinger Sub Bottom Profiler is also capable of operating in Bathy mode. The Dry End system is equipped with a toggle switch, allowing operators to select between receiving on the large aperture array or receiving with the projecting transducer (additional transducers sold separately). If you have a requirement for a shallow water sub bottom profiler, and need a standard bathymetric system for the same vessel, the Pinger is a good option to consider for your geophysical exploration.

Depth rated to 200 m, this system offers surveyors the flexibility of being able to operate in shallow or deep water.
C-MAX CM2 DIGITAL SIDE SCAN SONAR
The CM2 towfish incorporates dual frequency operation, with a choice of two configurations, DF (100/325kHz) and EDF (325/780kHz).
For general survey tasks DF towfish are often the most useful. In 100kHz mode the search swath is up to 1000m wide, useful for searching for larger objects such as wrecks or freight containers. In 325kHz mode it is usually possible to distinguish such objects as mooring ropes, anchor chain, anchors, scour marks, pilings, crab pots, rocks (down to the size of a briefcase or less), as well as differences in seabed texture.
EDF towfish offer the highest resolution. Like the DF towfish they offer 325kHz operation out to 150m. The EDF’s 780kHz frequency gives the most detailed images, very useful for positively identifying an object first located at 325kHz.
JW FISHER DUAL FREQUENCY SIDE SCAN SONAR 100K/600K
JW fishers underwater dual frequency 100k and 600k side scan sonar system provide a visual image of vast areas of the ocean floor.

This unit is popular for military, dredging operations, fisheries and for large scale environmental studies. Fishers offer three different frequency side scan systems; the SSS-100K, the SSS-600K, and the dual frequency system SSS-100K/600K. The SSS-600K has very high resolution over ranges of up to 200 feet (400 foot swath). This system is ideally suited to search for small or soft targets. Applications for this system include: searches for old wooden wrecks, scattered debris fields, ghost nets, logs, drowning victims, mine countermeasures (MCM) by the military, and a variety of other targets. It can also locate larger targets such as sunken vessels at ranges of up to 200 feet. The SSS-600K is in use by law enforcement agencies, dive rescue groups, and military units worldwide.
EDGETECH 560P TOPSIDE AND MODEL 272-TD DUAL-FREQUENCY TOW FISH

The towfish is equipped as standard with EdgeTech’s patented Saf-T-Link recovery system which will prevent the loss of the towfish if it becomes snagged on an obstacle during towing.
Frequency: 100/500 kHz
Max depth rating: 1,000m
JW FISHERS PROTON 4 UNDERWATER MAGNETOMETER
The PROTON 4 is the fourth generation magnetometer from JW Fishers. The Proton mag is the “work horse” of the commercial salvage industry and the preferred choice of many professional wreck hunters. It can locate a variety of iron and steel targets including sunken vessels, anchors, chains, cannons, moorings, pipelines, submerged vehicles, and lost equipment. The PROTON 4 is a top performing microprocessor driven marine magnetometer detection system with one gamma sensitivity. It features a triaxial noise-cancelling sensor that allows omnidirectional towing without heading error or dead zone. The system is fully digitized and displays it’s output on an easy to read 5 digit LCD that is backlit for night operations. An alarm informs the operator when the readout changes, and Tracker software allows the operator to see the path of the boat as it moves over the search area, ensuring no piece is missed. The magnetometer readouts and position coordinates are displayed in an easy to read format on the computer, and all the data can be saved for future reference. The towfish has excellent hydrodynamic characteristics, moving smoothly through the water at tow speeds up to 10 knots.
