Elevate your standards.
Boutique TDI & SDI dive training and premium gear on the shore of Lake Okanagan, built on small groups and rock-solid fundamentals, from your first breath underwater to full technical, cave and instructor certifications.
Why Double Arrow
Diving done properly
We teach the way we dive, deliberate, safe, and never rushed. That starts with buoyancy on day one and carries through every certification we offer.
Small groups
A maximum of four students per course means more water time and real coaching, not a crowd.
DIR-styled courses
We teach to a DIR (Doing It Right) standard: consistent configuration, trim and team skills that carry from your first dive through to technical and cave.
Premium gear
Train on XDEEP, Waterproof, SI Tech and Seal dry suits, equipment built for comfort and cold water.
Tech-ready path
A clear ladder from Open Water to Trimix, cave and rebreather, with instructors who actually dive it.
Training Pathways
Find your next certification
Four tracks, one progression. Start anywhere that fits your experience, each course links to the one before and after it.
