I ended up snagging a set of these for my
Mavic 2 Pro (not my setup, stock photo from the Internet):

And, from this photo, apparently you can get these for the Mini as well. I compared these to the dual foam pontoon design you'll also see online; these appear to keep the Gimbal higher and out of the water better than those. I also have the LifeJacket, but I got stability? (I don't recall the exact warning) warnings when flying with the lifejacket AND prop guards, or did, so I've been using these instead (prop guards as I sometimes fly in amongst the plants for more up close nature photography (wetlands mostly).
I like these because, being BRIGHT orange, they help with VLOS. As I mentioned, I happen to like doing videos and photos of wetlands up here in Massachusetts which involves some pretty tricky flying at times to avoid branches and plants (I try to get close in some of my shots). I did some photos and videos of Wrack Meadow at the beginning of September, and I'm planning to hike back out there again next weekend to get some more video with fall foliage colors. That's a huge bog area and I definitely will want to keep it out of water and findable in the dense woods/marsh area.
The only issue with this setup is you have to be careful with maneuvers when filming as those bright orange spheres can protrude into the video for fast flying or turns, but works well in Tripod mode. I've yet to test this, but in theory, the
Mavic 2 Pro will float on water if it lands with these on. I also got a waterproof
Marco Polo for the possibility of having the drone go down over wetlands and dense wilderness. At least I'll be able to recover the drone IF I can to it's location. With wetlands behind my house, there's some areas of dense muck that would be hard to get to even on my own property, but at least I'll know where the drone ended up. I'm hoping that my fly fishing waders will get me out to the drone should it go down in those sort of territories.
One last item: DJI has a page on flying drones over water; they recommend disabling the Visual Positioning System (VPS) when flying below 3' (IIRC). Here's their guide:

I feel less anxious if I have these on when I am flying over water. Yesterday, I did a hike out to Wachusett reservoir to get some shots, but didn't bring the floats, so I did all my imaging with the drone over land, looking out into the Reservoir. I got some very nice photos I may post.
And, if anyone is in central Massachusetts who'd like to do some hiking and drone photography, give me a shout!
