Hello, i have one question. I'm the water rescue from Poland and we have this sonar. Is it good to find body in water or not? Can we ser the body on the monitor?

Beginner here! What a great content! You were able to grasp the concept and explain it effectively to the audience. Thank you for this

Thank you, Mr. Lipinski. this will go a long way in my education to help locals in my country. Your extensive knowledge on the subject matter is absolutely astonishing.

Thank you for the information provided, it was very helpful!

What's app number plz

Sonar to find vehicles in thewater.,lakes,

Excellent side scan class. Success, thank you very much!

hi, wanted to thank you for this class, im a chilean underwater archeologist and this was very usefull...btw, have you been to chile? i noticed the last picture where chilean marines.

What is the cost of the side scan sonar?

This is beautiful work. We are currently going through a class and they completely failed to inform us of these 4 principles. Thank you so much for your help and I would love to connect with you and see if we could get your assistance with the area.

Thanks for sharing your professional knowledge here! Do you believe that SSS can scan moving object like whale and submarine etc?

Awesome video, and for EMS applications, it's effectively true, but the speed of sound is not constant in water.

👍

Hello Sir, we are looking to purchase an imaging system that allows us to "see" the bottom of a inclinated dam wall down to 40 mts deep, before we put divers in the water to install sealing fabric over cracked areas of the wall, need to have the most possible good definition, depth reading , measuring the objet observed and GPS location, all data to be set on a mosaic graphic plane Hope I could make myself clear in my explanation Spanish is my mothers tongue

Good Job Regan! Keep them coming! Very helpful information!

Sir, can you suggest a software for simulation of SSS sonar images (xtf, MBE) for research purpose ? We need a software for generating synthetic sonar images for modeling and testing. If you can suggest one , it will be very helpful sir. Thank you

Is there any toolkit for artificially synthesizing side scan images for academic purpose to conduct research ? It will be extremely helpful for me if you suggest some toolkits for that . Thank you sir

This might help you describe how different frequencies of an acoustic wave produces different imaging, especially resolution and distinguishing between objects in close proximity. The key component is actually the horizontal beam width (for a tow fish system) that a transducer produces. Higher frequencies use different, more directional, transducers which produce more narrow beam widths. Think of the horizontal beam width as a knife, cutting into an object. The more narrow, the more cuts or slices of the object, the more you're going to see of that object. This is also how objects that are near each other can be separated and displayed. The down side to higher frequencies is reduced scan range. All frequencies from the time they're generated through a medium (like water), will dissipate power over time. The higher the frequency, the more rapid the power loss...hence less range. Sonar systems are regulated in the amount of power they can generate. I think Mark Atherton may have described this a bit in his book, Echos And Images.

Wow, love that image of the pickup truck at 9:56 in your video. BTW, that's a Ford Ranger..part of a homicide investigation in Cincinnati. It was taken using a technique that we developed using Marine Sonic HDS 900Khz. My name is Ken Purcell. There still might be a few at Marine Sonic that remember me. When I say we developed it... we did. In fact, this is a vertical scan. Now, Marine Sonic did have a method and a clamp system to allow rotation of the tow fish, but the way they describe to do it was not correct. After sending images of bridge piers and a car, using our way...John DeMille and others asked me to write up an article on this. It was published in Ocean News and Technology, August 2012 edition. In fact, it was the feature story on page 10. Now today, many cheaper systems can do the same, but most have the transducers mounted to the vessel. But, with a tow fish, you control the depth and the scan range which is big advantage. By getting the tow fish closer to the object, you can reduce the scan range, which increase the size and (believe or not) the resolution of the image. The one car image we did, you can see the door handles, window rolled down...almost the lug nuts on the wheels. Not kidding.

I learned a lot from this video. I hope to buy a side scan sonar for finding targets to explore, while diving, on our state's largest lake. I can see I would have made many mistakes in buying the wrong electronics for my boat.

Wonderful info! I am just getting started with this and hope you will discuss tricks for scanning through a thermocline if no towfish is available.

Great content and easy to follow explanation of terms.

Thanks Regan.

Great presentation--thank you

Keep them coming Regan! I like the short bite sized format.

Very very very pedagogical video, helped me understand a lot of things on side scans as a engineer point of view thanks a lot

Thank you very much. This is the best clip with a lot of knowledge transfer. I learned so much, I vote this for the best education vid.

So awesome you share this stuff

Amazing overview - Are there freely available MST/ XTF / side scan sonar software packages around that you can recommend? (looking to play around with some data for my university studies :) ) Would be amazing to see things in a waterfall type view :D (or is sea scan survey free software? That's amazing if it is!)

Thanks a lot. The lecture was beneficial. I wonder if I can find written material about it

Muito Obrigado, era o material que estava precisando pra estudar sobre SSS para meus exames... Explicação de forma simples e objetiva.. Salvou meu dia.

Hi Regan, I just bought a (preloved) SSS600 JW Fisher and am an avid wreck hunter. Having no experience in SSS your video was extremely informative. I will look forward to watching more informative videos from you.

Great vid! I think you mean "The tow fish couldn't care less", as to be able to care less means that the tow fish currently cares.

These side scan videos are great! Thank you for sharing.

Hi there, thanks for the comprehensive lecture. Do you mind sharing why would sonar transmission in air damage its transducers?

Hi Common Man , thanks for this great presentation firstly, watched all your videos, again thanksç. I want to design a sonar for AUV but i don't know where to start . can you help me ? by the way ı am a student at departmant of EEE thank you so much :)

Excellent video Regan. Extremely informative, great work!

Great stuff. Really enjoyed all the videos. Very useful.

Great presentation, well-designed, informative and engaging

Great presentation!!! Thank you!

Thanks for this nice lecture. Is there a reason for completely ignoring AUVs? Some of the problems you mentioned during your presentation could be solved by using an AUV. So I'm just wondering why it is not even mentioned.

I watched the live recording of this ... a ton of great info presented in an easy to understand language... Keep up the great job ... Thanks a bunch

AWESOME VIDEO ... will be following ... THANK YOU
