Here’s an awesome surfing video with a wipeout recorded with the GoPro Surf Hero camera.
You can see how wide the angle is especially when he points the camera down from the top of his surfboard while on the beach. An extreme wide angle is especially important if you want to get immersive videos like this.
The GoPro Hero cams are one of the widest angle pov cameras available with an extraordinary 170 degree angle of view. Ordinary miniature digital cameras like the Canons have a much narrower wide end at only 60 to 75 degree angles of view. Plus they are not waterproof and the waterproof housings cost the same price as a complete Gopro with mounts.
