I recently dropped my GoPro into a lake while filming some footage. My heart sank – until I remembered the buoyant housing. This experience highlighted the importance of understanding whether a GoPro floats, especially for underwater adventures. This guide will explore everything you need to know about GoPro buoyancy, helping you avoid a similar near-disaster and ensuring you capture stunning footage, no matter the environment.
GoPro Buoyancy: The Basics
This section explains the fundamental principles governing whether a GoPro floats or sinks, considering the different components and factors influencing its buoyancy. We’ll clarify the role of the GoPro case and its impact on overall flotation.
The Role of the GoPro Housing
- Waterproof Housing: The waterproof housing significantly affects the GoPro’s buoyancy. Most housings are designed with a degree of flotation built in. This extra buoyancy is usually enough to keep the GoPro afloat, even if the camera itself sinks.
- Material Density: The density of the housing material is crucial. Materials like polycarbonate and ABS plastic have a lower density than water, contributing to flotation. Understanding the specific material properties of your GoPro housing will assist in assessing its buoyancy.
- Air Trapped Inside: Even a small amount of air trapped inside the housing can greatly improve buoyancy. This is especially true for housings that are not completely sealed or have small air gaps.
The GoPro Camera Itself
- Density of the Camera: The GoPro camera itself is denser than water and will sink without a housing. Its internal components are made of materials, such as metals and circuit boards, that have a higher density than water, thus increasing its weight.
- Weight of Accessories: Adding accessories like external microphones, lights, or filters will increase the overall weight and decrease buoyancy. Every additional gram adds to the overall density and can significantly impact the GoPro’s ability to float.
Factors Affecting GoPro Floatation
Several factors can influence whether your GoPro remains afloat. This section explores these variables and their combined effects on your GoPro’s buoyancy.
Water Temperature
Water density changes with temperature. Colder water is denser than warmer water. This means a GoPro might float better in warmer water and may sink more easily in colder, denser water. This is a subtle effect, but it can be noticeable in extreme temperatures.
Saltwater vs. Freshwater
Saltwater is denser than freshwater due to dissolved salts. Consequently, a GoPro might float slightly better in saltwater compared to freshwater. This is because the buoyant force is slightly greater in denser saltwater.
Depth of Water
At greater depths, water pressure increases, making it slightly harder for objects to float. This impact on GoPro flotation is minimal at typical recreational diving depths but becomes more noticeable at significant depths.
Testing Your GoPro’s Buoyancy
It is crucial to test your GoPro’s buoyancy before relying on it in the water. This section demonstrates safe and effective methods to verify if your GoPro floats.
Controlled Test in a Pool or Tub
- Fill a bathtub or pool with water.
- Carefully place your GoPro (in its housing) in the water and observe its behavior. Does it float or sink? Note the orientation and how much of the GoPro remains above the waterline.
- Repeat the test with different accessories attached to determine how they influence buoyancy.
Realistic Scenarios and Case Studies
- Scenario 1: A surfer uses a GoPro with a waterproof housing to capture waves. The buoyancy of the housing helps keep the camera afloat even if it’s knocked off their board.
- Scenario 2: A diver uses a GoPro without a housing and accidentally drops it into the ocean. Because the GoPro is not buoyant without a protective case, it sinks.
Debunking Common Myths About GoPro Buoyancy
Myth 1: All GoPro housings are equally buoyant.
This is false. Different housings use various materials and designs, leading to varying levels of buoyancy. Always check the specifications of your specific housing model.
Myth 2: A GoPro will always float, even without a housing.
Absolutely false. The GoPro itself is denser than water and will invariably sink without a properly sealed, buoyant housing.
Myth 3: Adding a floaty arm guarantees buoyancy.
While a floaty arm adds some buoyancy, it doesn’t guarantee the GoPro will float if the overall weight (GoPro + housing + accessories) exceeds the buoyant force provided by the arm. It depends on the arm’s volume, shape and the GoPro’s weight.
FAQ
Does my GoPro Hero 11 float?
Whether your GoPro Hero 11 floats depends entirely on whether it’s in a buoyant housing and what accessories are attached. The camera itself will sink, but a suitable housing typically provides enough buoyancy for it to float.
What if my GoPro sinks?
If your GoPro sinks, it’s crucial to retrieve it quickly to prevent damage from water or loss. Consider using a retrieval system like a floating wrist strap or a specialized GoPro retrieval tool.
Can I add weights to make my GoPro sink faster?
While you can add weights, it’s generally not recommended. Intentionally sinking your GoPro increases the risk of damage or loss, especially in challenging underwater environments.
How do I increase my GoPro’s buoyancy?
You can increase buoyancy by using a more buoyant housing, reducing the weight of attached accessories, or using a floating arm or handle.
What happens to a GoPro if submerged for too long?
Even with a waterproof housing, prolonged submersion can lead to water damage if the housing is compromised or if water manages to seep in. It’s vital to use and store your GoPro correctly.
Is a floating handle necessary for underwater filming?
A floating handle isn’t strictly necessary but can significantly improve safety and ease of use, especially when shooting in moving water or at greater depths. It offers an additional layer of security against accidental drops.
Are there any waterproof cases specifically designed for flotation?
Yes, many waterproof cases are available for GoPro cameras and are designed with features to improve flotation. Some cases incorporate additional buoyant materials to enhance the GoPro’s ability to stay afloat.
Final Thoughts
Understanding whether a GoPro floats is paramount for successful underwater filming. Remember that the GoPro itself will sink, and a properly sealed, buoyant housing is essential. Always test your setup before venturing into the water to ensure you can capture those incredible moments without incident. By understanding the factors affecting buoyancy and taking preventative measures, you can enjoy worry-free underwater photography and videography.
