I have a blind swimmer and it's fascinating how other senses magnify and compensate (ears, pressure/feel, etc). He can swim a 25y length and never hit the lane ropes, and I often have him split the lane with another swimmer. Most are amazed to find out he's blind.
Thanks for advice. He must be extraordinary swimmer. I will soon be like him in swimming with close eyes. I love to swim that way but It will take time for me to be the perfect.
