In this video, I’m helping you solve a very specific problem: “What’s a solid $800 Christmas gift for a scuba diver?” There’s a ton you can buy in this price range, but if I’m picking one gift that feels special and is useful for just about every diver, I’m going with a dive computer—specifically the Mares Sirius. It’s one of the same computers I use, and it’s an easy win whether the diver is brand new, already experienced, or planning to level up later. What I like about the Sirius is how versatile it is. It works as a full-time everyday wristwatch, but it’s also built to handle recreational diving and technical diving. You can choose a silver face or black face, and you can customize it with different strap colors. For divers switching between wetsuits and drysuits, the strap system is super simple to swap, and it even comes with a longer strap that’s great for thick cuffs. Add in the option for a bungee mount and Bluetooth connectivity to the Mares and SSI apps, and you’ve got a computer that’s intuitive to learn, easy to live with, and future-proof for most divers.
