Summer time...incredible viz in this spot, unlike during winter.
What a blast we had in Trou Madame...The winter 200m sump is completely different during summer. Extraordinary visibility (30m+), max depth 3m and mostly a lake (only a 30m-long overhead).
It was a great opportunity to cool off underground with Nicolas Monchaud and light big volumes with BigBlue Dive Lights Europe CB30000s and CB10000s.
Not really a "big dive" so to speak, but such a great photo shoot.
More to come on my website...
