To tell you the truth, I purchased it to use as a registrar. Weary of the disregard for the law on the roadways, etc. Before that, I had seen a GOpro that belonged to a buddy; I'm not sure which one it was, but I liked the concept behind it.

It shoots pretty accurately and can also capture photographs. I have not yet attempted it while submerged because June of this year is not at all like June of previous years.

It is always kept as a registry in the car, and during the warm months, the whole family uses it to go swimming and take pictures underwater.

I utilize aquabox in addition to charger. The end, as they say. The conclusion was that the camera had done its job.
