Rendezvous picks you up in Port Alberni not Ucluelet despite being Barkeley Sound based. You can actually see their lodge on Google Earth here.https://www.google.com/maps/place/48%C2 ... 125.018938
Peter and his wife (I forget her name) are good operators. They are unlikely to go out as far as Ucluelet, that's a lot of fuel for them and they don't really dive in the northern portions of the Sound that much.
There are no scuba businesses currently in Tofino, its more of a surf town at this point. You could call and ask one of the surf shops to see if there's a compressor running someplace out there. The scuba shop in Port Alberni closed a number of years ago as well, so absent local knowledge about a compressor, your nearest fills are way back in Nanaimo.
