The setup and connecting is easy enough. In fact it’s something I think a diver owning their own gear should learn to do so that they can do a better job at checking their gear between services and such. However having said that, if you are asking then you should probably take it to your local shop just to be safe. They might be a bit disappointed that they didn’t get a chance to sell you the gear but you could always pick up a couple little accessory’s while you wait. :)
