Comments: EANx 33. Surprising amount of surge on this dive, even at depth. Dived with new fins (Scuba Pro Twinjets). Dive felt tiring and my mind isn’t fully made up on these fins yet. Saw 1 baby lionfish and that was the highlight.

Comments: Headed left into very little surge. Used my Force Fins again which felt so much better. I’ve not given up on the Twinjets, but they’re going to have to do something spectacular to make me turn away from my current fins. Saw 2 octopii, plenty of lionfish, cuttlefish, 2 mating seasnakes and a huge nudibranch on a very pretty dive.
