SeaLife SportDiver Ultra (SL405) Underwater Smartphone Housing

The SeaLife SportDiver Ultra (SL405) is a premium underwater smartphone housing designed for divers and snorkelers who want to capture stunning underwater photos and videos with their own smartphone. Rated to 40 meters (130 feet), this universal housing accommodates most smartphones up to 192 x 95 x 15 mm and features Bluetooth LE connectivity for seamless integration with the SeaLife SportDiver App. Its robust polycarbonate body with stainless steel hardware ensures durability, while the integrated vacuum pressure alarm provides peace of mind against leaks. The housing includes a removable red color-correction filter to restore natural colors at depth, and a large shutter lever for easy operation even with gloves.

Advantages

With the SportDiver Ultra, you can transform your smartphone into a capable underwater camera without sacrificing touchscreen functionality. The Bluetooth connection allows you to control settings and view live previews via the app, while the five control buttons and large shutter lever provide tactile feedback.
