My son (9 years old) and I will be visiting Jacksonville from Dec 26 through Dec 30. We are both strong swimmers and have visited several of the natural springs in northern Florida. I am trying to get some basic private lessons for us to get an introduction to free diving. We have masks, snorkels and fins purchased from a real diving store. I’m sure it’s not top notch stuff but I believe relatively decent. We’ll travel an hour or two to get some private instruction. Can anyone help us out. Thanks.
