Best Sonar 3D Sonar ?

[utomo]

Hello All,

I just new here.
I want to ask about the sonar.
Mostly I read about side scan sonar.
But I read that 3D Sonar is good to find ship wreck
3-D sonar provides new view of Civil War shipwreck | Fox News
If I am not wrong the use the blueview

Any Ideas how good and how expensive it is compared to side scan sonar ? and also the coverage too.

Thanks

Seems like regular side scan. Just not very clear at all. Side scan is like a picture of the wreck. Very clear.

Well, I'm not sure about that one but I can tell you that one the best 3D Real-Time underwater sonar's is made by Coda Octopus (CodaOctopus Products Ltd.). It is awesome. How do I know? Because I used to work for them and I was one of the operators who trained the US Coast Guard, various police forces, US Navy, etc. on how to use it. it's not cheap.. for the kit you should plan to spend a minimum of $250k to $500k for that.

Looks to me like its a rotational side scan sonar that is deployed at different locations around a site. The data is then post processed to create a 3d image. The technology is probably more about the software than the actual sonar.

anybody can give info about the different of the side scan and 3d sonar ?

It is expensive.
as you work on the company before can you explain more on the 3D sonar ?

I think there is other features. not only the software

There is a fair explanation of the technology here that is fairly non-technical: NOAA Ocean Explorer: Bermuda: Search for Deep Water Caves 2009: How Multibeam Sonar Works . Pretty similar to sidescan in principle but with quite a bit more data scanned.
The number of data points that have to be acquired, processed, stored and displayed to produce a clear 3D image is huge, so the computer processor(s) manipulating the data will be expensive.
In order to get a useful comparison of technologies available today, one has to specify a budget. You can spend $50K or $10 million. Just like cameras, clarity increases with cost.
