Buying online is convenient. However, when you buy online, you get no support.
No one is there to help fit gear to you and your body style. No one is there to help
give you real world information, both good and bad, about your choices. Only a
knowledgeable, experienced dive shop can help you make the right choices, and
stand behind you no matter how long you own your equipment.
When you buy on-line, you're on your own.
