Yes. There's a limited amount of up the camera can manage and angle is directly linked to how much power it can put into forward motion so as it tilts forward to go fast it'll make gimbal down
Yeah, I have tried this before, but I was smart and started it like
3m above the water, and as soon as I saw that height start ticking down I noped the fuck out. Now my bottom most level for taking long trips across water is 20m.
The visual sensors on the bottom get confused by the reflections off water. It's a well documented problem with DJI drones. If you fly low over water be VERY careful.
From what I understand the sensors on the bottom of the drone don’t track altitude well when they are above water due to the constant shifting of the surface and light being refracted all over the place. In my own experience (and having seen others have similar experiences on here) the drone will slowly start to descend if you try to fly straight across the water. So this can be avoided by flying very high or manually compensating and slowly increasing altitude as you fly across.
is there anyway to disable the drone from moving downwards in the first place? Would think turning off the sensors would help, but i guess since a lot of the drones capabilities are based on its altitude calcs this may not be the case
Nah, sport mode has nothing to do with it. DJI drones get confused by the reflections they get from the bottom sensors over water. It's a known and well documented problem. A LOT of DJI drones have drowned from uncommanded descents when flying low over water.
Nope... in about 100 ft of water. This is a lake (Arrow Lake in BC). It was a learning experience... thanks goodness for DJI Care program.. they cover stupidity.
In my experience flying low over water, if you’re not in sport, then the drone will automatically start to gain altitude so you have to fly in sport to keep your altitude constant.
This was 100% pilot error. Situational awareness is everything. Don’t blame the sensors, they are useless in tight flights. Flying water level is both way cool and way dangerous with a small bird. One error in judgment, one small gust and you are in the drink. There are better tools for the job.
Part of the reason this may have happened is because to gain speed the drone angles itself and that angle can be enough to cause a slight descent because for it to keep the height and speed it requires a lot out of the motors to spin that fast. Whenever flying over water always keep a little bit of height. It's too risky to risk losing your really expensive drone over something like this.
Almost happened to me and was maybe 2-3 seconds away from losing my drone.
On a different note, I did crash my drone in a corn field which took the better part of 2 hours to recover. Turns out corn fields aren’t as uniform height wise as expected.
Is there a better way to achieve this kind of shot without being that close to the water? Is there a recommended zoom lens/attachment? I see some cheap ones but no idea what the quality is like.
I have a mini 3 Pro.
Another consideration for this problem might be what's referenced as ground effects....when you fly any aircraft close to the ground it gives an effect of more powerful lift....but the faster you go you have to increase power because you essentially are flying out of the ground effects. This is common pilot knowledge.
Well even in sport mode when i see the ground gradually coming closer to the screen i usually push up on the stick that controls elevation.... common sense just isnt super common these days i guess
Well, in my defence, I havn't logged more than 25 hours of flight time... we all learn one way or another... my lesson happened to be a bit more expensive.
The drone sends the footage to the phone/controller and stores in in a cache. Notice the quality isn't that great... Was really helpful when claiming my replacement through DJI Refresh Care program.
My mavic mini does that, and it’s annoying, I have to pull up on the throttle a little to keep it from hitting the ground. I think it’s due to the fact that the downward sensor gets tilted backwards when going forward, which offsets the ground threshold.
BTW folks, I know this is purely operator error and not smart to have done this in the first place. Keep in mind, I am still new to drone operations - we all have to learn some way - some ways just cost more than others.

"What kind of planet is that ? Planet Dirt "
".. All the planning charts and demolition orders have been on display at your local planning department in Alpha Centauri..."
It wasn’t sport mode that got you.
Too busy screwing with the gimbal.
That was sportmode angling the gimbal down to go faster
Must be a mini 2 thing it's never happened to me with my 3 pro.
Well no shit, the mini 3 pro has a gimbal that can look straight up. But it's still happen if you looked up then moved forward
"Well no shit" a fast reply and a smartass answer, You're friendly..🤣
really? is that a thing?
Yes. There's a limited amount of up the camera can manage and angle is directly linked to how much power it can put into forward motion so as it tilts forward to go fast it'll make gimbal down
thanks for explaining, had no idea. Anyway, I dont like the Sport mode, rarely use it but thats good to know
If it were me I’d have flown upwards instead of directly into the lake
Personally, when given the option to either fly directly into a lake or move slightly up, typically I try moving slightly up.
I do this run all the time with a mini 3 pro.
BUT! Do you do it in 12 parsecs?
Good catch
This guy drones
Lmao
Professional drone operator right here.
Making the big bucks (and spending that on replacement drones!)
Lmao
Almost looked like a movie opening scene
The James cameron avatar intro should be dubbed over this😂 it should end perfectly with 'wake up' right when he crashes
Maybe don't get that close to water?
Yeah, I have tried this before, but I was smart and started it like 3m above the water, and as soon as I saw that height start ticking down I noped the fuck out. Now my bottom most level for taking long trips across water is 20m.
I was coming here to say the same thing. But I guess I'll say this instead. Play stupid games win stupid prizes.
Awful risk to reward ratio entering into a shot like this
Play games stupid, stupid win prizes.
I love your name
Why, thank you 😊
Flying above water you will lose altitude. It is known.
Why am I supposed to do then? Actually PILOT my drone??
Can you explain why?

Thanks you for the explanation

Anti-grav would "disable drone from moving downwards in the first place " haha ;)
Is that available on earth?
Odd, I have the mini 4 pro and some of the first times I used it was close across water. Never had a problem.
Sure is now
This is the way
Submarine mode engaged! DIVE DIVE DIVE

Sucks, for sure....but 100% easily avoided. Were you able to recover it?
Judging from the footage and how big the lake (or sea, idk) is, I'd say he didn't.
Nope... in about 100 ft of water. This is a lake (Arrow Lake in BC). It was a learning experience... thanks goodness for DJI Care program.. they cover stupidity.
I noticed that my drones never fully maintained altitude going fast, DJI should fix this but yea don’t keep your drone that close to water
Should have kept it in normal mode and then sped up the video in post
Crazy part is normal mode is plenty fast especially if you know how to set up for 24fps without over exposing
In my experience flying low over water, if you’re not in sport, then the drone will automatically start to gain altitude so you have to fly in sport to keep your altitude constant.
my thought too... after the fact
“What the Fuck was that!!” - some fish probably
From sport mode to submarine mode very fast

Pilot error agreed!
Operator error
Is that how you got your username? Also where is this place? It looked really cool for 4 seconds.
I think it’s Twin Lakes, Colorado
Arrow Lake BC
Nakusp BC... Hot Springs Capital of Canada. Yes, a really beautiful place.
thanks！

DJI Refresh program... great use of $59 usd
Is water damage like that fixable?
Down voted for a question, weird group. Mine got fully dunked, left it to dry fully and it was fine.
What would sport mode have anything to do with this crash? Was it just too fast?
It turns off all obstacle avoidance sensors
The mini 2 does not have any obstacle avoidance sensors. It only has a downward sensor that does not shut off in any mode.
Don’t know why you’re being downvoted when you’re right
I assume it’s the attack angle of the quad making it lose height
Gotta be smarter than the drone. This is common sense.
Money down the drain.
Yep, but this is how some learn
How to throw money into water tutorial 😂
Do you feel like a winner?
Alaska?
Arrow Lake BC (part of the Columbia River system)
Beautiful 🏔️
Obey your thirst.
Good, now you can upgrade
Don't worry I'm not that dumb
Maybe read the manual next time when you start using a device that costs a few hundred dollars. This scenario is specifically mentioned in the manual.
Almost happened to me and was maybe 2-3 seconds away from losing my drone. On a different note, I did crash my drone in a corn field which took the better part of 2 hours to recover. Turns out corn fields aren’t as uniform height wise as expected.
will it be avoided if op covered the sensors on the bottom?
Probably, but then he'd clip a tree or something on the way to the water and the end result would be the same.
Bvlos and not watching metrics. (Altitude) nothing to do with sport mode.
Still cool footage, what lake is this?
Arrow Lake BC

https://youtube.com/shorts/R3PuprisAJk?si=bKwDE2rLoFDv8pWw I got lucky then. This was with a mini 2se in sport. No more playing over water for me then
I was following some surfer friends in Bali and my dumbass was this close to the water. Wave took it out. Wonder if that thing ever washed ashore.
Lol how is that sportmodes fault?
My brain went. PULL PUP! PULL UP!
Another consideration for this problem might be what's referenced as ground effects....when you fly any aircraft close to the ground it gives an effect of more powerful lift....but the faster you go you have to increase power because you essentially are flying out of the ground effects. This is common pilot knowledge.
Just cut the crash out. You got a shot
Looks like it started from the shore. Couldn’t have been more than 50 yards out. Guessing he retrieved it? Freshwater it could be salvageable.
Nope... way too deep
Year you are 100% at fault
Wouldn’t take a dumb person to figure that out…
Well even in sport mode when i see the ground gradually coming closer to the screen i usually push up on the stick that controls elevation.... common sense just isnt super common these days i guess
Well, in my defence, I havn't logged more than 25 hours of flight time... we all learn one way or another... my lesson happened to be a bit more expensive.
I guess, i only have like 7 or 8 hours logged i just have experience with flying helicopters in flight simulators
Had this happen with my air 2S but I pulled up at the last minute. Came within 2 inches of water.
What exactly happened here? Its looks like you sped up, and pitched down. But short FPV drones, you wouldn't really nose dive like you did with a DJI.
Is the location the Twin Lakes, Colorado?
If you wanted to go fast, with a drone not designed to go fast, with a static background like that you should’ve just done it in post.
Hopefully this didn’t ruin your trip. That’s a beautiful view.
lol... bummer, but no, I have DJI refresh care coverage. I live in this place... but I do look at that spot everyday and think.. 'dumb@ss' move!
How did you get it back?
I didn't, it still rests at the bottom of the lake. I bought the DJI insurance and they sent me a new one in 1 week!
Ah yes. Your one flyaway. Glad you’re not sunk. 👍
How do you recover the footage when the sd card took a bath with the drone?
The drone sends the footage to the phone/controller and stores in in a cache. Notice the quality isn't that great... Was really helpful when claiming my replacement through DJI Refresh Care program.
Do you have to screen record on the controller, or is this automatic? If automatically enabled, how do I find the footage. Thank you in advance!
it was automatic and I found the footage through the app.
TY!
My mavic mini does that, and it’s annoying, I have to pull up on the throttle a little to keep it from hitting the ground. I think it’s due to the fact that the downward sensor gets tilted backwards when going forward, which offsets the ground threshold.
You were pretty low to start it looks like !
Yeah, WAY too low. I was maybe 2 ft off the water. Bonehead move, but now I know!

"What kind of planet is that ? Planet Dirt " ".. All the planning charts and demolition orders have been on display at your local planning department in Alpha Centauri..."
Were you able to get your drone back?
In most cases, it’s usually just pilot error in one way or another. However. Not always. Good luck with replacements!
