After all the rain we have had over the last few weeks, the river visibility is probably about as bad as it gets. The 1.5m of water is cold, fresh and pretty clear. We then descended into the brackish band of water as the clean fresh water coming down the river swirls together with the more salty tidal water from the ocean below. Needless to say that means you can’t see anything, not even the dive computer right in from of my nose. Below around 6m, that disappeared leaving us to head down to the bottom through a suspension of silt. With the vis ranging from about 2m at best and down close to zero otherwise it was a fairly short dive.
Day dive visibility around 5m for my second trip out with the 5D in the ikelite housing. First go with manual settings all round and the strobe in TTL mode.
