Water and electricity don’t mix, and when a drone falls into water, the electrical components are at risk of short circuiting. This can cause the drone’s systems to fail, leading to a complete loss of functionality. Even if the drone is designed to be water-resistant, the sheer force of the impact can compromise the seals and allow water to seep in.
Circuit Board Damage
The circuit board is the brain of the drone, controlling everything from navigation to propulsion. When exposed to water, the circuit board can suffer irreparable damage, rendering the drone useless.
Motor Failure
The motors are another critical component of the drone, responsible for propelling it through the air. When submerged in water, the motors can suffer corrosion and mechanical damage, making it difficult or impossible to recover.
Water Damage Severity: A Classification System
To better understand the consequences of a drone falling in water, it’s essential to classify the severity of the water damage. Here’s a system to categorize the extent of the damage:
Category 1: Minimal Damage
In this category, the drone falls into shallow water, and the impact is minimal. The drone may suffer some water exposure, but the electronics and mechanical components remain functional. With proper drying and cleaning, the drone may be recoverable.
Category 2: Moderate Damage
In this scenario, the drone falls into deeper water, and the impact is more significant. The drone’s electronics and mechanical components may suffer some water damage, but the extent of the damage is limited. Recovery is possible, but it may require professional assistance.
Category 3: Extensive Damage
This category is the most severe, where the drone falls into deep water, and the impact is catastrophic. The drone’s electronics and mechanical components are likely to be ruined, making recovery impossible or extremely challenging.

Floating Devices
Attaching floating devices to your drone can help it stay afloat if it falls into water. These devices can be as simple as a Styrofoam float or a custom-designed flotation system.
Quick Recovery
Speed is essential when recovering a drone from water. The faster you can retrieve the drone, the less time it spends submerged, and the less damage it will suffer. Have a recovery plan in place, and be prepared to act quickly.
Drying and Cleaning
Once you’ve recovered the drone, it’s essential to dry and clean it as quickly as possible. Use a soft cloth to wipe away any excess water, and avoid using heat to dry the drone, as this can cause further damage.
Professional Assistance
If you’re not experienced in recovering drones from water, it’s best to seek professional assistance. Companies specializing in drone repair and recovery can help you restore your drone to its former glory.
Real-World Examples: Drone Recovery in Action
While drone recovery can be a complex process, there are examples of successful recoveries that demonstrate the importance of quick action and proper techniques. Here are two real-world examples:
Example 1: Ocean Recovery
In 2019, a DJI Matrice 210 RTK drone fell into the ocean while filming a commercial shoot. The drone was submerged for approximately 30 minutes before being recovered. Through quick action and proper drying and cleaning, the drone was restored to full functionality.
Example 2: Lake Recovery
In 2020, a recreational drone pilot accidentally flew their drone into a lake. The drone was submerged for around 10 minutes before being recovered. Using a flotation device and quick drying techniques, the pilot was able to restore the drone to working order.
Conclusion
While the prospect of a drone falling into water can be daunting, it’s essential to remember that accidents can happen even with the best safety protocols in place. By understanding the consequences of water damage, taking precautions, and knowing how to recover a drone from water, you can minimize the damage and get back to flying as quickly as possible. Remember, speed is key, and professional assistance can make all the difference in recovering your drone.
| Category | Description | Recovery Likelihood |
|---|---|---|

| Category 2: Moderate Damage | The drone falls into deeper water, and the impact is more significant. | Moderate |
| Category 3: Extensive Damage | The drone falls into deep water, and the impact is catastrophic. | Low |
By understanding the severity of water damage and taking the necessary precautions, you can ensure that your drone is protected from the risks of water exposure. Remember, it’s always better to be prepared and take preventative measures to minimize the damage.
What happens to a drone if it falls in saltwater?
If a drone falls in saltwater, it can be disastrous for the device. Saltwater is highly corrosive and can cause significant damage to the drone’s electrical components and machinery. The salt can penetrate the drone’s casing and cause corrosion on the metal parts, which can lead to permanent damage.
Immediately after the drone has fallen in saltwater, it’s essential to retrieve it as soon as possible and thoroughly rinse it with freshwater to remove as much salt as possible. Even if the drone appears to be working correctly after being rinsed, it’s crucial to have it checked and serviced by a professional to ensure there’s no underlying damage that could cause future problems.
Can a waterproof drone fly underwater?
While some drones are designed to be waterproof and can withstand being submerged in water, they are not designed to fly underwater. Waterproof drones are typically designed to survive accidental falls into water or to capture footage in wet conditions, but they are not submarines.
If you need a drone to capture footage underwater, you’ll require a specialized underwater drone or remotely operated vehicle (ROV) designed specifically for that purpose. These devices are built to withstand the pressure and conditions of being underwater and can provide high-quality footage.
How do I dry a drone after it falls in water?
Drying a drone after it falls in water requires careful attention to detail to minimize damage. First, turn off the drone immediately to prevent any short circuits. Remove the battery and any other accessories, and gently pat the exterior dry with a soft cloth. Avoid rubbing or applying pressure, which can push water further into the drone’s internal components.
Next, use a desiccant or silica gel packets to absorb as much moisture as possible from the drone’s internal components. You can also use a hair dryer on a low setting to gently warm the drone and speed up the evaporation process. However, be cautious not to apply too much heat, which can damage the drone’s electrical components.
What are the consequences of a drone falling in freshwater?
If a drone falls in freshwater, the consequences are generally less severe than if it falls in saltwater. Freshwater is less corrosive than saltwater, and the damage is often limited to the drone’s electrical components and internal mechanisms.
However, it’s still crucial to retrieve the drone as soon as possible and dry it thoroughly to prevent any corrosion or damage. Even if the drone appears to be working correctly after being dried, it’s a good idea to have it checked and serviced by a professional to ensure there’s no underlying damage that could cause future problems.
Can I repair a drone that has fallen in water?
In some cases, it may be possible to repair a drone that has fallen in water, but it depends on the extent of the damage. If the drone has been submerged for an extended period or has been exposed to saltwater, the damage may be too extensive, and repair may not be possible.
If the drone has been retrieved quickly and dried promptly, it may be possible to repair or replace damaged components. However, it’s often more cost-effective to replace the drone rather than attempting to repair it. A professional drone technician can assess the damage and provide guidance on the best course of action.
