The problem with Dutch dives (or particularly the lake diving) is not so much the vis, which can be excellent, as the amount of light, which is often absolutely zero. A lot of the lakes are old peat diggings, so the water has bits of the black stuff in it, and beyond a certain point that means it's like doing a night dive in the middle of the day. Where by a certain point, I mean maybe 15 metres.

And that dive looks completely nuts. Was that part of a general diving holiday? And would you recommend Mexico?
