Waterproof to 50 meters, Garmin's new VIRB X and XE HD action cameras need no external case for underwater shooting. They also feature enhanced video and audio modes and more mounting options than previous models. The X and XE come with multiple built-in sensors and wireless functionality. Both shoot high-definition video (up to 1800p/30fps for X; 1440p/30fps for XE) and 12-megapixel photos at 30fps. The cameras also feature G-Metrix, which lets you track and overlay how fast, far, high and intense your experience truly was. VIRB X costs $299.99, and XE costs $399.99.
