Peter is currently leading a cave exploration in Quintana Roo, Mexico, also known as the “Pit Project”. Its progress can be followed on the Add Helium website.

Peter is the inventor of TruDive, an innovative and accurate method for dive planning. This system is currently being built into a platform for general use and will be released in the near future.

Sean’s interest in diving began with his first OW dive of the beach. Since that first dive, he has trained non-stop, exploring different depths. After starting his normoxic and trimix classes, he began to realize the benefit of diving with a rebreather – more cost-effective with the potential for deeper dives.
