Built for Dive Schools & Rental Fleets

For rental and training operations, a dive computer needs to be easy to understand, consistent across the fleet and straightforward to maintain.

The CR1 keeps the interface focused on the functions most recreational divers actually need. This makes student briefings simpler and helps instructors work with the same familiar setup across multiple rental units.

The user-replaceable battery also allows dive center teams to handle routine battery changes easily, helping minimise equipment downtime.

Whether you are building a new rental fleet, replacing older computers or adding more units for training courses, the CR1 offers a practical balance of simplicity, functionality and value.
