When planning international dive travel with your Dive Rite O2ptima CM closed-circuit rebreather (CCR), proper preparation is essential. The O2ptima CM’s compact and chest-mounted design makes it one of the most travel-friendly rebreathers on the market, but there are still logistics, packing considerations, and best practices that every diver—especially technical and CCR-certified ones—should know.

In this guide, we'll walk you through how to efficiently and safely prepare your O2ptima CM for international trips, so you can focus on what really matters: exploring the world’s most exciting dive sites with confidence and comfort.

Why the O2ptima CM Is a Great Choice for Travel

One of the biggest challenges technical divers face when traveling is the bulk and complexity of their gear. Fortunately, the Dive Rite O2ptima CM was designed with portability in mind.

  • Compact and modular: The chest-mounted design reduces bulk on the backplate, making it easier to pack and maneuver through airports and boats.

  • Airline-friendly packaging: With proper disassembly, most components fit into standard-sized checked luggage.

  • Streamlined for overhead environments: Whether you're flying to Mexico’s cenotes or the wrecks of Truk Lagoon, this CCR offers excellent balance for caves and confined wrecks.

Step-by-Step: How to Prepare Your O2ptima CM for Travel

1. Plan Ahead with Documentation and Airline Policies

Before booking your flight:

  • Check the airline’s policies on scuba gear and rebreathers, including battery and cylinder regulations.

  • Print and carry MSDS sheets (Material Safety Data Sheets) for any absorbents or oxygen sensors you’re bringing.

  • Label gear clearly to avoid delays during customs inspections.

2. Disassemble for Transport

Break the unit down into travel-friendly sections:

  • Remove the counterlungs, scrubber canister, and oxygen sensors.

  • Securely pack the electronics head, making sure the Shearwater controller (if integrated) is padded.

  • Disconnect any cylinders, which should be emptied and have valves removed for air travel.

3. Pack with Protection and Compliance

  • Use hard-sided luggage or Pelican-style cases for delicate parts.

  • Wrap hoses and electronics in bubble wrap or soft clothing.

  • Keep the Shearwater controller or NERD 2 display in your carry-on bag to protect against theft or damage.

4. Manage Your Sorb and Gases

  • Traveling with pre-packed sorb (CO₂ absorbent) is risky due to international regulations. It’s best to order or confirm availability at your destination.

  • For oxygen and diluent cylinders, confirm compatibility with local fills and fittings. Consider renting locally or shipping tanks in advance for long trips.

Tips for a Smooth Dive Trip with Your CCR

  • Do a full pre-trip check of your O2ptima CM several days before departure to avoid surprises.

  • Test your sensors and electronics and pack spares, especially if traveling to remote destinations.

  • Carry a detailed checklist of all items so you don’t forget any critical components like O-rings, tools, or lubricants.

  • Join forums or contact dive shops at your destination to confirm support for CCR divers.

  • Have a back-up dive plan in case a part fails or shipping is delayed.
