I'm hoping this is an upcoming firmware update and not a refurbished replacement drone? Documentation is vague about precision landing. Orange circle, A.K.A. takeoff point. My drone did a nice job trimming the weeds and landed where it sits. The first time I tested, it stopped around 6 feet and asked if I wanted to continue. I manually landed on the concrete that time. Yesterday it tried to land on the roof.

Look on the bright side, this new feature means you wont have to buy a landing pad as it'll never find it.

....or you need to buy one 30ft across instead.

Not to mention what I can save on trimming the grass.

Looking at where you took off from, right on top of concrete, I’d say precision landing is the least of your worries, all that grass and you decide to take off from concrete.
If you choose to read the manual you will read not to take off around concrete construction and only use RTH in emergency situations.

I have found my RTH accuracy varying a bit lately. I think it could be down to the number of satellites locked at take off. I find the nearer I get to 20, the more accurate my RTH is. I have been waiting now for the maximum number of satellites to be locked, whereas before I took off as soon as I got the green light.

Not sure I understand. The rear propellers are sitting in the grass making it unsuitable for taking off. It's pretty easy to land manually. My Mavic Pro nails the circle every time regardless of surroundings.

Again read your manual don’t take off around concrete constructions like you did, and only use RTH in emergency.
I’m sure it wouldn’t take much to place your pad on the grass thus avoiding possibility of interference to your compass , your pad won’t save you from that.

Satellites wont help fix this, DJI removed precision landing which uses the downward cameras to get it within inches.  Without that you're on GPS accuracy which on a good day is about 10ft, a bad day, twice that.

Concrete is fine as long as theres no rebar in it.  

You wont get it to hit that landing pad EVER at the moment - the drone lacks precision landing.

The Mavic Pro takes a picture of the landing spot. It then returns to the general vicinity with GPS and lands using the image. That's my understanding at least and my results have been impressive. Nice party trick, press a button and the drone lands on a dot.

There is no concrete construction near me. I'm taking of from a concrete deck in the back yard. Flown the Mavic Pro here for almost two years. Taking off and landing from concrete isn't an issue. Concrete buildings, bridges, whatever, are. Anything that could interfere with the signal. Putting the landing pad in the grass is an idea but if the drone is slightly off when landing it could dip the props into the grass.

Then control it, how do you think people managed to land their drones before precision landing, whether you have precision landing or not you should always allow at least 3 metres 10 ft room for landing, and hopefully precision landing will come with FW update.

There are no problems taking off from a concrete surface, asphalt, dirt, grass or whatever. I've read the manual multiple times. I can land it easily where I want. These drones are highly intelligent and I am simply testing the automatic landing feature. My Mavic Pro hits the landing pad 95% of the time. I do not rely on it as a way to safely retrieve it. With practice, anyone can easily land the drone manually wherever they need or want with all sensors disabled. If DJI is stating that you cannot operate the drone anywhere near concrete, then what's the use? How can anyone take the hyperlapse videos in their tutorial? How can anyone in an urban environment use a drone? I can't believe I have to find a grassy, cushioned area to take off and land, I've never read that. You cannot even calibrate the gimbal if you're not on level, solid ground. You have to be able to takeoff from the same location.

Your Mavic Pro doesn’t have precision landing , you would know this from setting up your aircraft before you flew, you can land manually with sensors off or on , on would be better and safer.
But without getting discussion out of context look at video below it will explain taking off from concrete, and it is by far the biggest cause of compass problems bar none in these drones.

Hallmark doesn’t seem to realize that DJI may have disappointed some people by inexplicably removing a feature on all their other drones.

It’s almost as if he would say, “Who cares about barrel distortion, you should learn to fix it in post!”

And it is correct- there is NOTHING wrong with using concrete to take off your drone. It is the issue with rebar in certain structures, etc. I’ve been flying in urban environments for years with no problem.

Precisely. There is nothing inherently wrong with concrete or asphalt. And secondly,
There is no known reason to remove precision RTH, color profiles, and have barrel distortion. Hallmark is definitely proving something- unfortunately for him it’s not what he is intending to prove.

As I said before:

I'm pretty sure the lights are to keep position when it loses sats. The old mavic would drop into opti mode and use the floor to keep position. Problem was without a flashlight on the floor or a well lighted room, it didn't work. It's kind of amazing to me everyone doesn't hand launch these things by now

Your comment about barrel distortion is both ridiculous and has no part in this thread, also you seem to saying that it’s ok to take off from concrete, but not concrete with rebar, how are we supposed to know if the concrete has rebar or electrical wires buried beneath the concrete, maybe take a look at the video.

Colour profiles were an added addition to Mavic Pro as was quickshots course lock and many other improvements in safety came with FW updates, as you are probably aware. And I believe it will be no different with M2.

Fine. Precision landing is a feature on even some of the cheaper DJI drones, as it was with the original Mavic series. Your semantic games make you look like a shill.

Please point out where DJI has explicitly stated this feature will be implemented in a successor drone that is supposed to replace the original Mavic series?

The fact that you state that the color profiles were “added” to the Original Mavic series doesn’t change the issue here. They are not in the successor.

And in terms of concrete- the original discussion had to do with precision landing- but there are plenty of scenarios where you would know that rebar isn’t in concrete. Here’s a strong hint: it wouldn’t be in the original poster’s picture. There is absolutely nothing wrong with him taking off or landing from there- also as evidenced by his extensive experience in doing so. I’ll leave that to you to figure out in between making excuses.

The Mavic 2 doesn't seem to have precision landing as of yet. This problem happens with most DJI drones that initially get released. Believe it or not, the current original Mavic Pro was a completely different drone when it first came out. Now after 2 years, it has been for most part almost completely perfected for its flying ability. DJI is making everybody be patient who purchased the new Mavic 2, it may take some time but eventually the Mavic 2 will land much more accurately. BTW: Do you really need the rocks to hold down the landing pad? What happens if the Mavic 2 lands slightly close to the rocks or its propellers accidentally come into contact with those rocks?

They haven't made any such claim about it being included.

And this isnt a rebar or electrical issue - its landing there because the feature that allowed more precise navigation no longer exists.  Nothing to do with concrete.

And manual is great - IF you can still communicate and talk to your drone.  Which isn't always the case.

When one’s default mode is to only be defensive, shill, play semantics, diminish the requests of others, or deny specific realities - that reveals a complete lack of objectivity and understandably calls into question his/her motives.

There’s no need for rebar in the construction of a concrete patio but their is wire screen laid down before concrete is poured. It’s in all concrete patios, sidewalks, etc.,etc. so it’s not a good idea to take off from this type of surface because of interference...

I would agree with you.
Precision landing was also added to my P4, along with some other goodies in the form of additional intelligent flight modes. So it seems feasible that additional functionality could be added to the Mavic Pro 2 and its sibling.

What was added to P4 with firmware update:-

• Added Gesture, Draw, Terrain Follow, and Tripod as Intelligent Flight Modes, as well as Trace and Profile sub-modes for ActiveTrack and a Free sub-mode for TapFly.
• Optimized Smart Return to Home, added Landing Protection, and Precision Landing.

So in terms of processing power it is likely that the Mavic Pro 2 & Co are probably quite capable.
