DJI’s newest addition to their line-up, the Matrice 200 Series, is a big deal. This is largely due to its IP43 water and dust resistance. The key term here is resistance

What does IP43 mean?
IP (International Protection Marking or Ingress Protection Marking) is a rating system for the degree of protection provided against intrusion. The rating applies to pretty much anything: body parts, plants, water, dust, etc. 
The first digit: level of protection against solids.

The second digit: level of protection against liquids. 
Please note that the liquid protection chart is fairly large, and the print would far too small if we inserted an image as above. BUT if you click the link, both charts are on the Wikipedia page for your close inspection.

Why is it important?
Most drones have an IP rating somewhere around 00 and need to be landed at the first sign of a slight drizzle. Having an IP43 rating means drone crews can stay out in a light rain if they haven’t gotten their shot quite yet. Image courtesy of DJI

Finally talking about the subject line.

QuadH2O is a drone manufacturer based in Worthing, West Sussex, UK. They’ve been around since 2012 and have a line of waterproof multirotor aircraft. 
Via QuadH2O’s FAQ page:
The body of the QuadH2O is a sealed, water-tight unit, with exception of the breather tube (which allow the barometer within the flight controller to measure outside air pressure, and are designed to let air in/out but not water) and the motors.

The brushless motors are exposed but can run if wet (and even underwater), however, we recommend you rinse them with fresh water after exposure to salt water to prolong the motor bearings.

The motors can run even if they are underwater. To compare, the Matrice 200 series IP43 rating protects it from “Water falling as a spray at any angle up to 60° from vertical.” 
We’re not saying this is better than the Matrice by any means, but if flying in the rain is your thing (or through a light waterfall maybe), then the QuadH2O product line is definitely for you.

The product line:

  • QuadH2O: rocking the company name, this unit is, of course, a quad (meaning four rotor). It comes as a kit (just the waterproof frame to build out as you like) from $849, or as a Ready To Fly unit from $2895. The unit comes with a built-in FPV camera and 5.8ghz transmitter, NazaV2 flight controller, the RC comes with an attachable Black Pearl monitor.

  • HexH2O: Up to 25 minute flight times, 2kg payload, motor failure redundancy, stabilized live video feed and did we mention it’s waterproof?” This unit has the option for an iPad ground station for tap-and-go waypoint flights, route planning, auto takeoff and landing, and more. Plus it has a gimbal for a GoPro inside its waterproof housing, so all you need is a GoPro to attach. Features the same standard setup as the Quad. Frame Kit: $1049. RTF: $3785.

Overall, the QuadH2O lineup looks to be awesome. Especially the Pro, with its DJI components you know you’re getting the reliability and ease of use that comes with DJI products; but waterproof.
