10 Best Cheap Underwater Cameras 2025 in the United States

The AKASO EK7000 4K30FPS 20MP WiFi Action Camera is an affordable option with several impressive features. Its waterproof depth rating of 131 feet makes it suitable for various underwater activities, and the durable waterproof case ensures protection in extreme environments. The camera offers high image quality with 4K video at 30 frames per second and 20MP photos, though it may not be as sharp as more expensive models. The built-in Electronic Image Stabilization (EIS) helps deliver smooth and steady videos, especially useful for capturing fast-moving objects or activities.

The 4X zoom in photo mode adds flexibility, but the zoom quality might not match that of higher-end cameras. Durability is one of its strengths, given its rugged build and ability to withstand harsh conditions. The battery life is decent with two lithium polymer batteries included, providing enough power for extended use. The camera is user-friendly with easy controls and a 2-inch screen for framing and reviewing shots. The wireless wrist remote control offers convenience, though it is not waterproof, which limits its use in fully submerged conditions.

Video capabilities are enhanced by the Wi-Fi connectivity, allowing for quick sharing and editing through the AKASO GO app. However, the Wi-Fi range is limited to 10 meters. Additionally, the camera requires a microSD card, which is not included. The AKASO EK7000 is a solid choice for those seeking an affordable underwater camera with good performance and features, though it does have some limitations in terms of image and zoom quality compared to higher-end options.

The Olympus Tough TG-7 is a compact and rugged camera designed to handle underwater and outdoor adventures without breaking the bank. It can be submerged safely up to 50 feet, making it a solid choice for casual underwater photography. The 12 MP sensor produces decent image quality for everyday use, with options to shoot in RAW format for better editing flexibility. Its 4x optical zoom and 25-100mm equivalent focal length cover typical wide to moderate zoom needs, especially useful underwater where changing lenses isn’t an option.

The camera’s build is impressively tough—it's shockproof, crushproof up to 100 kgf, freezeproof to -10°C, and dustproof, so it can survive harsh environments beyond just water. At 249 grams, it’s lightweight enough to carry around easily. Battery life is reasonable for day trips, though long underwater sessions might require backup power. The TG-7 is user-friendly, with a clear 3-inch LCD screen and straightforward controls, making it a good fit for beginners and casual users. Video recording supports 4K resolution and high-speed modes, adding flexibility for creative filmmaking.

Image stabilization is digital rather than optical, which may result in some blur during fast movements underwater. Additionally, while the camera is waterproof, it has a 50 feet depth limit that may not suffice for deeper dives. For those seeking a durable, easy-to-use camera suitable for snorkeling or shallow dives that offers decent photo and video quality at a budget-friendly price, the Olympus Tough TG-7 represents a strong choice.

The AKASO Brave 4 is a budget-friendly underwater camera that impresses with its range of features. It boasts a 4K video resolution at 30fps and 20MP photo quality, ensuring high-quality captures both in and out of water. One of its standout features is its waterproof capability, allowing it to handle depths up to 131ft, making it suitable for various water sports like swimming, surfing, and diving. It also features image stabilization, which is essential for capturing smooth videos, especially in active environments.

The adjustable viewing angles and dual screens (2-inch rear and 0.96-inch front) add to its versatility, making it easier to frame and review shots in different scenarios. However, its optical zoom is limited to 1x, which might not be sufficient for users needing closer shots without moving closer to the subject. The camera's build is lightweight yet durable, weighing just 5.6 ounces, which is handy for prolonged use.

The inclusion of Wi-Fi and HDMI connectivity allows for easy sharing and viewing of videos on larger screens. Battery life is decent with the two included 1050mAh batteries, each providing up to 90 minutes of recording time. While this is adequate for short adventures, longer trips might require additional charging solutions. Ease of use is a plus, with the camera coming with a variety of accessories, including a mini selfie stick and a bicycle/motorcycle kit, enhancing its usability across different activities.

In summary, the AKASO Brave 4 offers excellent value for its price, with strong video and photo capabilities, good waterproof depth, and useful accessories, though it could benefit from better optical zoom and extended battery life for more demanding use.
