I have a few here, if it's your first then don't go that complicated or expensive, have a look at the DJI stuff, their controllers are considered the best out there and you can get something in the air for under £500 - that's before you add camera gear. There are a few waterproof options out there, just google waterproof quadcopter.
If you are new to flying RC things then buy a Blade MQX to learn on, you get everything you need in a box for £100. These things look easy and fun but there is a lot to learn.
There are a lot of rules out there, even down down to needing a commercial pilots license if you fly for money and be careful if you start to put video transmitters on them - do the research before you get your credit card out.
If anyone fancies learning to fly or needs any guidance then I'm happy to lend a hand, it's a great thing to do when the cold weather sets in - I thought about using mine to film the RIB but didn't fancy the landing, be a pity if the blades hit the tubes.
This is a good deal but I'd go for a Quad to start with.
