One of the best masks I have had for the coins is the Crystal Vu by ScubaPro. You can get them with or without a purge. You can get it under 50 bucks with shipping and all. I have bought more expensive masks that I didn’t like. I didn’t like the Mares Demon mask for example. It must have been made for someone with a really large nose. The visability with the crystal vu is the best. It fits my face well and doesn’t leak. The purge makes mask equalization a breeze. Let me know what you think if you get one. Be sure to check out the reviews on Leisure Pro as well. Below is a link to the product
