The Best Phones for Cave Diving: Rugged Devices for Extreme Environments

Cave diving is one of the most challenging and extreme activities, requiring specialized gear that can withstand harsh conditions—submersion, high pressure, and rough handling. While most smartphones aren’t built for such environments, a select few rugged devices are designed to survive the depths. Here are the best phones for cave diving that combine durability, waterproofing, and essential features for adventurers.

1. AGM Glory Pro: The Ultimate Underwater Companion

The AGM Glory Pro stands out as one of the most rugged smartphones available, with an IP68 & IP69K rating and MIL-STD-810H certification. It can survive underwater at depths of 1.5 meters for up to 30 minutes, making it suitable for shallow cave diving. Its thermal imaging camera is a unique feature that can help divers detect temperature variations in underwater caves. Additionally, the 7,000mAh battery ensures long-lasting performance, crucial for extended expeditions.

2. Ulefone Armor 12 5G: A Balance of Durability and Connectivity

For divers who need 5G connectivity without sacrificing toughness, the Ulefone Armor 12 5G is an excellent choice. With IP68/IP69K and MIL-STD-810G ratings, it resists water, dust, and shocks. Its Sony Night Vision camera helps capture clear images in low-light cave environments, while the 5,180mAh battery keeps it running through long dives. The underwater touch mode ensures the screen remains responsive even when submerged.

3. CAT S62 Pro: Built for Extreme Conditions

The CAT S62 Pro is another top contender, featuring FLIR thermal imaging—ideal for detecting temperature changes in underwater caves. Its IP68 and MIL-STD-810H certifications mean it can handle deep submersion and rough treatment. The 4,000mAh battery is smaller than some competitors, but its efficient power management ensures reliability. The glove-friendly display is a bonus for divers wearing thick gear.

4. Doogee S96 Pro: Long Battery Life for Extended Dives

If battery endurance is a priority, the Doogee S96 Pro delivers with a massive 6,350mAh battery. Its IP68/IP69K and MIL-STD-810G ratings make it resistant to water, dust, and drops. The night vision camera helps in dark cave environments, while the underwater mode optimizes touch sensitivity. Though not as feature-rich as the AGM Glory Pro, it’s a reliable and affordable option.

5. Samsung Galaxy XCover 6 Pro: A Rugged Flagship Alternative

For divers who prefer a mainstream brand with rugged features, the Samsung Galaxy XCover 6 Pro is a solid pick. It has IP68 water resistance and MIL-STD-810H durability, though it’s not as extreme as some competitors. The removable 4,050mAh battery is a rare feature in modern smartphones, allowing for quick swaps during long dives. Its glove-friendly screen and decent camera make it a practical choice.
