Hello from the frozen waistlands of upstate NY. I discovered this SB sight yesterday while researching prescription masks. Thought I'd check out your forum. I'm newer to computers than to diving, and I'm no expert at that, so please bear with me. I do have two questions that some one might be able to help with. First I'm looking into prescription diving masks and especially bi focal prescription. Has anyone any suggestions or cautions? Second, I am planning a trip to Belize this March. Has anyone any input on the Hamanisi Resort. Thanks, Jim.
