Xplore Scuba offers a wide selection of dive gear

Don't dismiss the possibility of buying new scuba gear  

Most manufacturers nowadays offer some sort of “parts for life policy”. Buying secondhand gear voids that warranty and this is particularly relevant for items that need regular service, such as regulators. The amount of money you may have saved by buying a used scuba regulator pales in comparison to the amount you will spend every year paying for the labor AND the parts required to service your gear and keep it operating at its best. Spending a little extra money upfront for a new regulator may be worth it because, on top of actually getting a brand new regulator, you will be saving money on the long run.  

Do remember this is life-support equipment  

Saving a few bucks is well and all, but please remember every element of your scuba diving gear is meant to work together to keep you alive. If at any time you don't feel certain about the used scuba gear you are considering, even if it seems to be a very good deal, please consider getting a professional opinion. No deal is good enough for you to risk your health and well being. You need Scuba gear that is fully functional and serviceable, for the safety of you and your loved ones.
