Because the scuba regulator is an important piece of the Total Dive System, most divers choose to buy their own instead of renting.    Divers who rent a scuba regulator will notice the action of regulator with will be different during each rental.    The rented regulator will be looser or tighter, deliver air forcefully, or have draw air in a forceful manner.      As many divers are aware, the goal of the regulator is to deliver air on demand at ambient pressure.    The comfort level with a regulator depends on how the diver breathes.     It is up to the diver to choose the regulator that works best despite what a dive shop recommends.     So choose a regulator that feels right to you.

If you are a new scuba diver renting or borrowing a regulator, take note of the brand and model and how it feels.   This will help determine your likes and dislikes for when you decide to purchase.

So when you are shopping for a new or used regulator, do consider the following:

• ergonomics:  How it is designed and how easy it is  to hold.
• Does it use Non-corroding metals like titanium or chromed brass
• purge button: How easy is it to press when wearing exposure protection or not .
• external controls: Making those fine adjustment to the air flow.
• Diaphragm vs. piston mechanics. Most divers prefer diaphragm regulators than piston because of its smooth movement and fewer moving parts.
• Balanced vs. unbalanced regulators.  Do not buy an unbalanced regulator!!!!!!!
• Buy new when you can.  If you must buy used, ensure it can be serviced by your local dive shop.
• Look for a warranty on new or slightly used regulators.
