Wreckage of the Brunswick

Estimating visibility on the Brunswick

We dived the wreck of the Brunswick in mid July, when the water was cold and the visibility was rather nice. While filming a bit of the wreckage (very overgrown), I came across Tony instructing Craig and Christo to swim fixed distances (one swam 10 metres, the other swam 12) so that they could estimate the visibility. It’s a simple exercise but one that helps to improve your ability to estimate distance underwater, which isn’t easy.
