i have dove with all 3 of the operations mentioned here. while all shops are going to have their good and bad said about them our perfered choice is scuba express
coastal scuba
we used to dive with them in the past. cameron is a good guy, and if any of you watch Orange County Choppers on the tv this is the shop mikey did his diving with,but he has his quarks. capt. buddy is a nice boat capt. buddy is a nice guy and has a lot of good stories to tell. the problem we ran across is they were in a rush to get back to the shop every day. not the worst thing in the world, but we like to get in as much diving as we can. now they did use to let us do three dive on the civil war wreck ( the governer as some might call it ) and i am not excatly sure why we stoped using them. now they did have a problem with some crap in the storage bottles one day and divers getting sick, but you could have that happen at any shop anywhere.
nu horizons
we dove with them once and had a blast. the converted a old navy boat into the dive vessel and it was sweet. hot water shower, air fills on board, and VERY FAST. they also had a suction pipe on board to do some digging in the sand if you found some good treasure. last we heard they sold that boat, and i have no idea what they are doing now. but if they are back in business ( with a boat is what i am refering to ) then they would be a good choice.
Scuba Express
jennifer and johnatan have made are recent trips to myrtle beach the best they have been in the last few years. we were one of the first groups to go out on the 46 foot newton when they bought it ( if you are in the shop and look at the big picture on the wall i think we are the group on it ). while sometimes they do get a loot of people on board, you will still have a good trip. they will allways have plenty of staff on baord. Karla will most likely be acting as divemaster and do the anchor while Joe will be teaching students. if not i am sure he would be glad to dive with somebody if they needed it. on our last trip i had an oring go on my 100% 02 bottle and they were happyto give me a new one at no charge. i dont know how many shops will give out a free viton oring. but they are always happy to make our diving the best it can be. if you go down there tell them the guys from Blue Marble Divers said hi.
hope this helps anyone who is having trouble deciding which one to use. i dont want to say one is better then the other, i just know who we will use from now on when we go.
good diving to all
