Hey Jeff, I am thankful to you. You are a wonderful teacher. I would not have dived in since I was scared of deep water (though it was just ten feet). I could trust you with the waters and had the most wonderful sight, I always loved watching the sunlight dim through the water as we go in. Thanks a ton. I will definitely get the certification done. I am not scared anymore, I feel more comfortable using the diving gear and the tank. Thanks once again. Vijetha
