I didn't fart - pretty sure they spotted me and bolted!
Sounds good, how deep were you diving? Ive just started diving in moderate/strong currents but I cant figure out which way to face is best; up or down current. Got any pics of your fish?
Not very deep - 10-12m max I should think.
In terms of which way to face - if I were a fish, I would either be saving my energy and drifting with the tide, or holing up somewhere and waiting for prey to drift past in the tide. So during Aspetto it would make sense to face uptide and wait for things to come towards you? In shallow water where you can see the bottom I would be tempted to
drift with the tide for these reasons;
saving energy
quieter
cover lots of ground
things to consider if doing this;
Sunlight - is your shadow ahead of you as you drift, spooking the fish?
Currents - are you going to be able to get back to shore?
Dark/reflective lenses - if exclusively surface hunting without a buddy, it might be permissible to wear these. Fish can see your eyes and don't like you looking at them. However, if you were doing deeper dives your buddy also needs to see your eyes in case you samba/BO. Something to consider.
Fins - you might want shorter fins which make for quieter finning on the surface. Reconsider if you think you can swim better in long ones (but they are louder in my experience)
Provisions - Take a float and load it up with snacks and water if you think you might be on a long session. Drifting can allow you to do longer sessions, so be prepared if you're going for it. Maybe put a drogue on your float so its always behind you, you can always wrap it up when you want to swim home.
If you are hunting in deeper water with currents these might be my thoughts;
Anchor a buoy on your chosen mark- you and your buddy need a reference point to find eachother. Dive around the buoy only and wait for fish to pass. One up, one down. The buoy can be rested on to breath up. This could be a kayak. Move spots if unproductive.
Short sessions - with tides in some areas of the UK up to 14m in height you don't want to start a session at low tide and get caught out a few hours later. Know your limits and stick to them.
Light - if you are undecided which way to face, look towards the sun. The silhouetted fish will appear from further away and your shadow (on descent) has spooked the fish in the opposite direction to where you came from.
Sound - I would be more inclined to grunt/croak/ping elastics in the hope of bringing a fish in from afar. Fish are more confident in deeper water - although I am not a fish, this is just a hunch
Loads more to think about beyond that, but now I'm bored of typing.
