Divevolk Underwater External Shutter for SeaTouch 4 MaxSeries Housings Divevolk's Underwater External Bluetooth Shutter makes taking video's and photos with your SeaTouch 4 Max Plus Smartphone housing even easier This device operates as an external shutter trigger for your smartphone giving you the feel of using a regular underwater camera trigger on your smartphone. Whilst being able to access the touchscreen is a key feature of the Divevolk housing, letting you access more controls quickly it is often easiest to start and stop recording using a trigger. Not only is it quicker but you will get more steady shots as your hands can remain in place on the housing or the tray so you are ready to capture the action smoothly every time. The Shutter can be installed directly on the SeaTouch 4 Max Housing using the included bracket or attached to the handle of your Divevolk Dual Tray with the included clip. Just like the Divevolk SeaTouch 4 housings the Shutter Trigger is waterproof to a depth of 60 meters. Compatible with SeaTouch 4 Max, SeaTouch 4 Max PLUS and SeaTouch 4 Max Platinum housings The Shutter is powered by a single CR2032 Battery which is included with your purchase with a battery life of approximately 50 hours.
