The night arrives shortly after 6 p.m. and the sun rises around 5 a.m. In this period of time, you may feel enveloped by the darkness in this part of South Africa. Andrea Murdock Alpini shares his adventure diving the Komati Springs.

What exactly is meant by "Rebreather Friendly"?

“Rebreather Friendly” dive centres—what exactly does this mean?
