Thank you for this video. If I need to simulate this, how can I know the central frequency, source-receiver distance, time window, etc? I am a beginner in this area. Thank you

This video is so helpful for beginners. Thank you!!!

Excellent class . Thank you very much.

Thank you for this video...

If there a cable that is scanned right next to a piece of rebar and the scanned pics up the rebate but not the PT . Who Is liable ?

Thanks for perfect and valuable instruction

Does it give information about the diameter of the rebar?

Hey Bigman, It's been 3 years pass I am still going learning new things, but als back some of your channel following your video. So please keep updating new things. Appreciated!

In your opinion, is this ds2000 more complete than a DSX?

is it possible to create a DIY version for a project?

Merhaba profesör, videolarınızdan çokşey öğrendim. Bir sorum olacak korumalı antenler, ormanlık alanlarda çalışırken gürültüye neden olurmu?

HOW DEEP does this devise reach?

what would you use this for??

Whats the height of the gs18 one a standard mounting? 1.3m?

What would be the easiest means to find the undergound limits of an old unmarked dump/landfill?

Hi Dan, We have been researching GPR for the last few weeks with a view to purchasing a vehicle mounted system. 88% of roads in Australia are unsealed dirt roads, most of the rest use ultra thin asphalt over approx 150mm to 300mm gravel then natural soils Additional information such as ground water table would be a possible advantage but less of a priority in our case. Air coupled antenna seem a safer option given the poor running surfaces we often encounter would destroy a ground coupled antenna. Do you have any recommendations on the best configurations of antenna ? I've read 2Ghz air coupled and 900 Mhz ground coupled is a good combination. Could we substitute the 900Mhz ground coupled for a air coupled antenna and mount it on the same arm.? Also is there a minimum distance the antennas should be located from a vehicle ?

What is that

Hello, are you acquainted with Radan 7 post processing software? i am trying to build a relation between gpr to density of soil by studying the velocity variation

Do you guys walk in alternate mode? Is only one way? I mean, seems to me that one one line is created and the plotted due the GPS data. How do you guys put the image in the google map? Do you use surfer and then export?

i just bought that book . thank you so much

Thank you for explaining these machines!!! Great video!!!

The green pulse, how do we know if it is a void from the wave

thank you so mcuh for sharing! is that possible to read if there are any moisture different inside the concrete?

Nice work

Nice work

Sir my gpr shows odometer error

Love this. Even though it is raining you still go to the effort to do a video for us showing exactly what we need to see. Thanks Dan.

The video was very informative it has great insight into the operation of the unit. Your technician great. Maybe also have someone else hold the camera it was moving around too much. I really had a hard time seeing the screen.

Sir your watsapp number please I have gpr1000 but not working properly

🎉

What is the max depth of the ds2000 in a stone ground?

Great video

Does gssI operate the same without the frequency wheel and what is the difference? I have Gssi antenna 200 but don't have frequency wheel with sir 3000 Thx

How sign out the coffins ?

In my experience I believe it was internal antenna and soil. Because I have used it in different places where I can see my targets and the contrast was the same. I felt awkward in two different occasions where I couldn’t locate my targets. Thanks for your insight.

When your scanning for power as well and it spikes downward what does that mean ?

Great video What’s the maximum depth it can scan??

Isaac.

Which gpr unit scan utilities deeper than 15ft for the moderate soil type

Hi. Thanks for the video. Does the presence/ absence of waterfowl in pipes affect detection?

Hello my friends I am working on GPR. I need help. I want to .dat to .dzt . Do you have any information? Thank u.

how about wet sand? low RDP?

How to leaen radar system calculations

Congratulations on the video! We use this ground-penetrating radar, and undoubtedly, it significantly streamlines our services.

How many meters can you see the space under the ground and the object inside with metal separation?

Hello, I live in Turkey. The underground imaging device named Mala GPR Ramak x3 is rented here. What is the difference between it and the one you produce?
