Example of volumetric imaging of a rusted casing buried under 6 feet of beach.
Detects by material (ferrous, non-ferrous, organic) with GPS locating.
100-300' water and sub-seabed, depending on local conditions, target size, etc.
There is a marine platform in which the equipment is borne by 2 zodiacs, usually towed by a mother ship. It's not a handheld and must be operated by our crew on a service contract.
I now recall a similar thread existed about three years ago wherein 'ping' asked a Q that I don't find as having been answered; was it?

"This is very interesting technology for land. Thank you for your information.
For marine use however, nothing that is RF based can work. Water absorbs all frequencies of RF energy completely. Only a few inches of range would be possible at the operating frequencies the system uses."
Don....
Yes, we have a way to make it work on water and have done multiple successful marine demos for the US military which are classified. However, we can arrange for retired military officials involved with the demos to vouch for the tech and are happy to show proof at our lab in Newport Beach, Ca., to any interested parties who fit the following criteria:
1. US citizen
2. Not affiliated with any foreign government or foreign defense contractor
3. Professional, serious treasure hunter.
This guy has been peddling this 'top secret technology' for years. I asked for a simple explanation of the principles involved, because I am extremely skeptical. Show me one, single paper published on this technology that supports the claims. Oh, I'm a physicist by the way, and I'm pretty difficult to fool.
Nothing came out of it.
The basic physics are as you point out. RF waves are absorbed by seawater. Therefore, anything that uses RF waves won't work underwater. Why do you think submarines use sonar instead of radar? It's pretty simple. The guy claims it doesn't use RF but some 'new' principle that has no academic citations whatsoever.

BakhtarRadar: Non-Invasive Exploration and Sub-Surface Imaging
Friday, August 31, 2007
BakhtarRadar represents a new generation in GPR. Originally developed by Dr. Khosrow Bakhtar under the U.S. Air Force Small Business Innovative Research (SBIR) program to detect buried ordnance, it is now available for mining and tunneling applications for the first time.
BakhtarRadar can be used for volumetric imaging of subsurface deposits, other forms of underground anomaly definition and water exploration. Using a newly invented principle called "Forced Resonance," it offers much higher resolution and enhanced signal-to-noise ratio (SNR), facilitating ease of analysis and discrimination as compared to conventional GPR-- and in 4D.
[Photo courtesy of Bakhtar Associates] Depth of penetration isup to, and even exceeding, 600 ft. (depending on antenna design). There are no limitations with respect to soils, lithology or degree of saturation of the geologic materials.
BakhtarRadar uses a ground-based system in which the antennae are pulled via a small tractor. The ground surface must therefore be sufficiently level as to permit the tractor to negotiate the surface and corners. Ground interrogation is triggered with a high resolution Global Positioning System (GPS), allowing transfer of the location coordinates onto any GIS system for site planning.
The technology is available through a service contract. The company will consider joint ventures in some cases.
Bakhtar Associates, a Small Physical Research and Development company located in Newport Beach California.
Organizational Interests:
Development of myriad mission specific electronic identification systems in support of our nations
security
Highlights:
Development of three prototype man portable & deployable systems for the detection of SNM in
shielded containers. (This program currently suspended due to budget cut backs)
Currently working towards automated "near real time" (2 to 3 second delay) Stand-Off Explosive
Detection". Recent feasibility / proof-of-concept testing showed ability to detect energetics in near real
time, at a distance of 11 meters,while being carried by individuals. (Project Status is ongoing
Subsurface Anomaly Detection & Location
Subsurface anomaly detection utilizing a propriitary "Forced Resonance" technology developed by
Bakhtar Associates. We have provided support to numerous entities within the US government for
subsurface detection. The unique "Forced Resonance" technology associated with a CoTS differential
GPS assist in determining anomaly existence, location, & depth with respect established reference points
place on the surface. System is capable of tunnel detection to tens of meters. Additional developed
software and post processing can produce 3-D image reconstruction of identified underground anomalies
as shown below. Data utilized to construct this image was taken from actual operational employment of
the EarthRadar.

No new good news?
Millions of dollars of Spanish treasure await those who would dare brave the eye of the hurricane.
I did yesterday speak to Dr Bakhtar about his system. Although I remain not entirely convinced until I can witness the system in operation, there does seem to be something to it. I may have been overly dismissive.
I will re-post here when I get more conclusive information.
