When you go snorkeling/freediving, do you prefer to use fins, or do you prefer to go without fins. I am a bit torn on this case. Without a doubt, I am faster with fins and I reach at least the same far as without fins. Still I often go without fins because I am consuming less fast the oxygen without which leads to longer times under the water. Also, I find fins a bit irritating when following the surface with the snorkel.
