Other people's footage, not advice: how someone else dives here says nothing about what suits your team. Dive within your training.

This is how the planner decides who in your team may dive this cave. Rules your own trip adds (organizer, a mail, the AI) show with your trip.
How to get there
~38 km west of Tsumeb, by the D3043, on private farmland; visits only with the owner's permission (the water rights are shared by several partners). According to an older source, apply for dives at least 3 months ahead. A rusty staircase down to the water.
