My GoPro Hero 4 camera, either the Silver or Black version.
Residing in its tiny reinforced plastic housing, its fully waterproof, and its 12m pixel camera provides excellent results.
The video capabilities in 4k is superb, but the thing i like most about them, are their tiny size and portability.
Obviously a larger digital SLR camera will take better shots, but they weigh considerably more, and theres always that doubt in your mind about what if the weather really turns nasty.
Condensation, damp and changes in humidity are no friends of expensive camera gear, that's why i like the GoPro camera, for its size, weight and portability, and it can be used in every kinds of weather.
