Tech Diving Essentials: Mastery with Shearwater Computers

Why do you see so many Shearwaters at our Pacific Northwest dive sites? Because they’re a great dive computer for beginners to tech divers!

Intro to Tech is a topic you will see us frequently discussing in the first half of 2025. Tech diving is not just about going deeper for longer. In fact, many Pacific Northwest divers are already using strategies and gear that would be considered “tech-level” in other waters.

Many divers get to a point in their dive career where they are considering- what’s next?

In this series, we will delve into how to advance as a “tech-level” diver such as perfecting skills like buoyancy & trim, propulsion, dive planning, improving rescue skills & use of alternative gases. To support their improved skills, serious cold-water divers also need redundancy in their gear, exposure protection appropriate for our conditions & gear to plan your dives.

Jade Scuba Adventures (360-233-6825) can assist you with building these skills & pairing the right gear with them!

Why is the Shearwater Perdix 2 perfect for every diver (including beginners)?

  • Large, bright, easy-to-read screen that you can customize (full color 2.2″ screen)
  • AA battery is easy to replace and long lasting
  • Vibration alerts help divers complete their safety stops without having to watch the screen
  • Easy navigation through options and excellent user interface
  • Air integration with the purchase of a Shearwater Swift transmitter for greater ease of monitoring your gas level
  • Internal dive log stores around 1000 hours of dives and easily uploads to your device
  • Solid history of firmware updates even on older computers
  • Worldwide two-year warranty

Why is the Shearwater Perdix 2 perfect for advancing/tech divers?

  • Great add-on to your current dive computer to start tech training (redundancy)
  • Integration with up to four tanks works beautifully for tech divers!
  • Most-used algorithm (Buhlmann ZHL 16-C) with Gradient Factors to customize your conservatism

What if I want a less expensive dive computer?

The Shearwater Peregrine is also an exceptional dive computer at a lower price point than the Perdix 2, but it does not have air integration. Is this a factor for the type of diving you do? What kind of diving are you expecting to do in the next five years? Air integration can be particularly useful for divers that might otherwise have their hands occupied (dive professionals, scubility partners), have trouble reaching/reading the face of an SPG, divers who like to measure their stats, divers with multiple tanks & more!
