Hey Murat, I ad the same problem: the little buggers are so sensitive and always get out of my way... One day I found that my booties keep air on them. When you are swimming underwater this bubbles are compress by the foot/fin and make lot's of noise.
Get on the water with out the hood, purge any air from your suit , and then put back the hood underwater. If is really cold you can get he same effect by laying back your head, hold out the neoprene on your forefront and expire: you will sink and all the air should get out (may need to do that twice)
Once your suit is air free, purge your booties by opening they edge while standing vertically and moving your foot until any air trap in there gets out. repeat that time to time: during surface swimming you could get some more.
If you fart all this process need to be repeated :yack ... but be cool, you can wee!
When you get back to the surface and get the snorkel back on your mouth, instead try to empty it with one of this big whoooosh that make you fart... and keep the fish away, just tip your head back gently while exhaling easily. Is better for you breathing too.
Instead been whoooshing your snorkel every 5 min trying to get rid of the last drops stuck on the bend :hmm , have a gentle roll to the same side you put your snorkel, and by magic it will be as dry you will never get it.
Make sure you are not loosing bubbles at the mask: you can see that when you surface... no bubble should follow you. keep a bit of negative pressure on the mask help me to avoid that.
Make your spear and flopper silent.
All this points have make a big difference on my hunting... and the fish I ambush are getting bigger.
You may think I'm paranoia but I'm building an hydrophone to check the effect of noises, like our hearts, on the fish... :duh :duh
