What Should I Buy First After My Mask and Fins?

We get this question constantly from newly certified divers: “What gear should I actually buy first?” Mask and fins are the easy answer — every new diver picks those up right away, since fit is so personal. The real question comes after that: computer or regulator set next? Both are important safety gear, and there’s no universal right answer. It really comes down to what matters more to you as a new diver.

It Comes Down to One Question

Ask yourself: which is more important to me right now — tracking and monitoring my dives, or knowing exactly what I’m breathing from?

The Case for a Computer First

A dive computer is tracking and monitoring your dive in real time — your depth, your remaining bottom time, your no-decompression limits, and critically, whether you’re ascending at the right rate. That last part matters more than new divers usually realize. It’s not just about knowing how much bottom time you have left — it’s about the computer telling you, in the moment, “hey, it’s time to go up.” That alert is what catches you before ascending too fast turns into a real problem, which is one of the more common ways new divers get themselves into trouble.

If having that safety net — a computer actively watching your dive and telling you when it’s time to ascend, not just showing you numbers — is what matters most to you, a computer is where your money goes first.

The Case for a Regulator Set First

The alternative is owning your own regulator set. When you rent gear, you’re breathing from a regulator set with a maintenance history you know nothing about. You don’t know how well it’s been serviced, how it’s been treated between rentals, or how it actually breathes. Every rental set is a bit of an unknown.

When it’s your own regulator set, you know exactly when it was last serviced, you know how it performs, and you know it hasn’t been handed off to a dozen other divers between your dives. For a lot of divers, that peace of mind — breathing from a regulator set they trust completely instead of whatever’s on the rental rack that day — outweighs everything else.

There’s No Wrong Answer Here

Both pieces of gear are about safety, just from different angles — one manages your dive profile and tells you when it’s time to ascend, the other manages what’s actually keeping you alive underwater. Think about which uncertainty bothers you more: not having something actively telling you when to go up, or not knowing what’s really inside the regulator set you rented. Whichever one keeps you up at night is the one to buy first.
