For scuba divers, the dive regulator is one of the most important pieces of equipment you will purchase. Your regulator is your lifeline as it is what makes breathing possible underwater. When selecting a regulator there are several factors to consider, but one of the most important to consider is if you will need a regulator that is designed to function in cold water. If you regularly dive in cold water or harsh conditions, you will have different needs than someone who only dives in warm water and in controlled environments. That’s where the Sherwood SR2 regulator can come in handy.
