Brian laundrie. >> authorities say dive teams and sonar systems are being used to search large bodies of water and confirm cadaver dogs have been in use throughout the entire effort which began saturday. meanwhile, social media continue to provide leads on brians steps before he disappeared. >> these internet absolutes and armchair detectives have come out in numbers. the amount of information that theyre able to pull has really been incredible and really help leading the investigation. >> i saw...

Something different than we havent already seen? >> not for a long time. so as they start to bring in a broader area search capability, and that would be using towed sonar systems, deep side scan systems, that process becomes slow. the area expands for surge. its just going to be the same kind of sonar maps that the bluefin-21 was generated, probably at a lower resolution, but now over a very large area. so the search could go on for months or a year, and its really an incredibly large area to t...

Its not necessarily an easy prospect. first of all, in the bluefin-21, in vehicles like this, that are able to go down to 4,500 to 6,000 meters, there arent very many of them in the world. its a very specialized technology. so mobilization, even getting the assets there, is going to be a big deal. very costly. and very complex. theres other types of equipment that can be used to. there are deep towed sonar systems that might aid in this. but all of thats complex. so as you start to expand the se...

Live from australia. for more on the investigation, lets bring in rob mccallum, cnn analyst and ocean search specialist and peter goelz, cnn analyst and former ntsb investigator. rob, the pal lags transport minister has stated he wants more under water drones. how many do you think he needs? >> it depends on the type of drone. if youre using an auv, a great machine for deploying sonar over a small area and getting high resolution im manuals, you need quite a lot of them because theyre only doing...

To the seafloor. in addition, you have to know where you are. that unmanned vehicle has controls for itself, got navigation systems, sonar systems. all those theys have things ha work in concert. its a very complicated process. >> they basically have been flying blindly because they havent mapped it. >> right, theyre doing their best estimate of whats down there to do their planning. >> i want you to show us what that mapping looks like until we can see how this works. >> theyre building a map r...

>> and the weather is rough today. that means they cant put the submarine in the water. which is -- i dont know. it works underwater. thats kind of hard to understand. >> well, so like a lot of things, the riskiest time for these types of systems is during launch and during recovery. and the rougher the seria, the higher the sea stake, the more likely for instances, for instance, a collision with a ship. when an auv and slip collide, the ship wins every time. >> i can see that. is there any sub ...

Capability is the passive and active sonar and theyre really sensitive. this submarine is used to track other submarines. so its sonar systems are super, super sensitive. >> so better capability to find things because its more sensitive with its detection technology. >> absolutely. it is listening for those pipgs. as we already pointed out, were down to the last few days of this now. the battery life could last up to 40 days. >> could also be 20 days based on how theyre stored. its just much mor...

That is great if you are looking for ships or land masses. its suboptimal if you are looking for aircraft debro. >> is that where a submarine comes in? you have the pinger draped below it and how does the submarine work? >> this is a hunter submarine and they have missiles. they have about 35 knots, quicker than the ocean shield. this is specific to the capability. this is the passive and active sonar. this submarine is used to track others. thats what it is designed for. the sonar systems are s...

Passive and active sonar. theyre really sensitive. this is used to track other submarines, hunt and kill russian subs. sonar systems are super sensitive. >> it gives more range because its faster and better capability to find things. >> absolutely. the listening bit, its listening for pings. as we pointed out were down to the last few days of this now. we know from experts, the battery life could last up to 40 days. were nudging on that final ten days. >> could be 20 days based on how theyre sto...
