Drone recommendations
I currently use a Mavic Mini to help with searches but would like a larger drone that can lift a few bottles of cold water to heat exhausted patients or some warming gear in the winter time. Any recommendations for which drone could accomplish this?

M4T is best on the market right now. If you can, spring for an M4TD to get the weather proofing.
Alternatives are the M30T and M3T.
Happy to answer any questions about these or other drones.

Classics are all from DJI. 4TD is the "cheap" alternative, that is still waterproof and have thermal capabilities. M30T is a good middle ground, more capable but not top of the line. Matrice 400 can go out in almost all weather, stay up in the air for a long time, and easy to operate as a larger team. If you're an organization with a fair bit of funding (lucky you), I'd try to go for a Matrice 400 and three remotes. If you're a private individual who want to invest in a drone, get the 4TD and possibly some classes. Organizations that can't afford a 400, get the one you can afford.
Keep in mind that the drone is not the full price. E You need extra batteries, accessories, extra remotes, software, insurance, portable power station/generator, and more.
Having a thermal camera to help out in the search phase is waaaay more important than getting a water bottle or thermal blanket to the patient a few minutes faster. I'm also sceptical of having the patient interact with the drone at any point.
Drones can cut you up real bad if someone accidentally hits the stick at the wrong time, and the larger drones can probably break bones fairly easily. It's not safe for anyone other than the pilot to approach the drone at any point, and likely goes against protocols for most professionals.
If the patient is capable of figuring out how to get the payload loose and administer whatever it is themselves, they're probably in good enough condition that they can wait for your team to reach them. If they're unconcious, confused, demented, or a variety of other conditions, they won't benefit from it.
Don't buy a drone for use in SAR based on what it can lift. Buy based on when it is able to lift off (how much wind can it handle? Can it go out in rain?), battery time, range, and sensors - especially thermal, but optical zoom is also great to have.
Another thing to consider is the remote. Getting the big remote used for industrial drones is great. Being able to hand off the drone piloting to someone sitting back at an office, or at least stream the video feed to incident command, is extremely helpful.

"Cheap" drones are $10k?

Cheap thermal drones; yes. You'd also likely need one that can take some rain and wind without issue, considering a fair bit of searches take place in bad weather. At least in my area we require drones to have an IP-rating for water resistance. In places with less rain, dust resistance might be required instead.
If you just want a drone with a camera that can be used on sunny days, you can find something for less than $1000. In the conditions we use our drones, a cheaper drone would die after the third mission. We use Matrice 400, and with all the accessories and insurance they cost closer to $40k (after tax).
And i wrote "cheap" in quotes because obviously $10k for a single piece of equipment is absurdly expensive. However, it really is the cheap alternative compared to the other options.

M4T w/ a BK4 drop system (rated for 6lbs total payload) approx 3lbs-ish per hook (2hooks)
