I am new to diving but have always felt very comfortable going into my LSD. The staff are very knowledgeable and are not shy about offering several options. They sell Deep Sea Supply, OxyCheq, Aqua Lung, ScubaPro,Mares, Bare and Halcyon.......that I am aware of. The few things I have ordered have been in and ready to pick up in 6-7 days. Don't know about tank fills and inspections (don't own) but I can say when I took in a reg set, that I had purchased elsewhere (new) they checked it over for me at no cost. In fact they even gave me a pat on the back and told me I had gotten a very good deal. I have been nothing but happy with their selection, service and attitudes and will continue to give them my business.
