This B&H Kit gives you a few basic accessories for the GoPro HERO4, which in many cases will be all you'll need. You get the compact Lowepro Hard-Shell Case which fits two cameras and accessories, the Joby Action Grip that can be used handheld or tripod/monopod-mounted, and which also floats in water, and a simultaneous GoPro Dual Battery Charger with a Battery for the HERO4.
The Dual Battery Charger with Battery for HERO4 allows you to charge two GoPro HERO4 batteries simultaneously. It is able to power from just about any USB power source - use the GoPro Wall or Auto Charger, a smartphone charger, a computer - even a USB backup battery. Dual LED indicator lights display the charging status, so you know when your batteries are ready for action. The charger includes a spare 1160mAh lithium-ion battery for the HERO4 camera.
Part of their Action Series line, Joby's Action Grip provides steadier hand-held shooting with your action camera, while doubling as a flotation device should you accidentally drop it in water. An integrated three-prong mount at the top of the handle allows you to attach a GoPro camera. For use with cameras that have a 1/4"-20 socket, an adapter is included. At the bottom of the handle is a detachable end cap, which features a wrist strap for additional security against accidental loss and drops. Unscrewing the end cap lets you attach an optional extension pole or any other pole that has the standard painter's pole threading.
The black, impact-resistant Dashpoint AVC 2 Hard-Shell Case from Lowepro is a lightweight, molded hard-shell case that holds two action video cameras such as GoPros, as well as accessories like housing and mounts between padded touch-fastened dividers underneath a soft interior lid within the main compartment. Additionally, the Dashpoint features a removable organization panel, which rests between the exterior and the interior lid to hold small accessories like adapters, batteries, remotes, and camera tethers. The case features a dual-zippered closure and can be carried using the built-in grip handle at the side.
