What Makes a Drone Waterproof?
A waterproof drone is designed to withstand exposure to water, but the degree of water resistance varies depending on the drone’s IP rating. The IP (Ingress Protection) rating is a standardized measure of a device’s ability to resist solid particles and water.
IP Rating Explained
The IP rating consists of two digits:
- The first digit represents the level of protection against solid particles, such as dust, on a scale of 0 to 6.
- The second digit represents the level of protection against water, on a scale of 0 to 9.
For example, an IP67 rating means the drone is completely protected against dust (6) and can withstand immersion in water up to 1 meter for 30 minutes (7).
Design Features of Waterproof Drones
Waterproof drones incorporate several design features to ensure water resistance:
- Sealed compartments: Electronics are enclosed in watertight compartments to prevent water ingress.
- Water-repellent materials: Drones are made with materials that repel water, such as hydrophobic coatings or nano-coatings.
- Gaskets and seals: Gaskets and seals are used to prevent water from entering the drone’s compartments.
- Drainage systems: Some drones feature drainage systems that allow water to escape, reducing the risk of damage.

Q: What makes a drone waterproof?
A drone is considered waterproof if it can withstand being submerged in water without sustaining damage. This typically means that the drone’s electronics and other components are sealed or protected in some way to prevent water from entering and causing harm. Some drones may only be splash-proof or water-resistant, meaning they can handle some exposure to water but shouldn’t be fully submerged.
The level of waterproofing can vary widely between drones, so it’s essential to check the specific specifications and features of a drone before taking it near water. Some drones may have waterproof coatings or seals, while others may have fully enclosed bodies that prevent water from entering. In some cases, drones may have specialized designs or features that allow them to dive or swim underwater.
Q: Can any drone be made waterproof?
While it’s technically possible to add waterproofing features to many drones, not all drones can be made fully waterproof. Some drones may have design limitations or components that can’t be easily waterproofed, such as complex mechanical systems or heat-sensitive electronics. Additionally, adding waterproofing features can add weight, complexity, and cost to a drone, which may not be desirable for every application.
That being said, many modern drones are designed with waterproofing in mind, and some manufacturers offer waterproofing kits or upgrades for specific models. If you need a waterproof drone, it’s often better to start with a model that’s specifically designed for this purpose rather than trying to modify a non-waterproof drone.
Q: How deep can waterproof drones dive?
The maximum depth a waterproof drone can dive varies widely depending on the specific model and design. Some waterproof drones may only be able to withstand shallow water or splashes, while others can dive to depths of 100 meters or more. The depth rating of a drone is typically determined by the manufacturer and is based on testing and simulation.
It’s essential to check the specifications of a drone to understand its capabilities and limitations. Even if a drone can dive to great depths, it may not be able to withstand the water pressure at those depths or may have limited functionality while submerged. Be sure to follow the manufacturer’s guidelines and recommendations for using your drone in or near water.
