1. Waterproof to 30M and HD underwater photography: The case allows you to dive deeper with your phone without worrying about potential water damage. Capable of withstanding depths up to 98ft/30m, it enables you to take photos or shoot videos underwater. The case features a 1/420 tripod mount for professional photography equipment like monopods, tripods, or stabilizers. 2. UNIQUE VACUUM DEVICE: Before using the product in water, you need to extract air from the iPhone diving case using a vacuum pump. This ensures better protection against water leakage and prevents screen fogging. The case is equipped with an improved sealing ring and tight buckles for effective water resistance. 3. 99.99% LIGHT TRANSMISSION: The case lens is made of ultrathick tempered glass with light transmittance, ensuring photo quality and clear, vivid videos. Your movements and shooting effects remain unaffected by water pressure. The body is crafted from quality PMMA plastic, providing durability to protect your camera lens and screen from drops, dents, and scratches. 4. EASY TO USE: Simply place your phone in the correct position, close the lid, secure the buckles, and use the vacuum pump to remove air. The camera controls function just like normal, allowing full access to settings such as timelapse, slomo, zoom, focus, lens selection, and seamless switching between photos and video.
