I covered that. There's maybe 5% of mainstream instructors that know how to correctly teach trim. As a student, you can't tell who can and who can't, and once you get to the point where you CAN tell if an instructor knows how to REALLY teach the class, you don't need the class anymore.SubMariner once bubbled...

Many new divers benefit from learning how to fine-tune their buoyancy, to estimate weighting, and learn proper trim through PPB . As with any course, finding a proper Instructor is the key to a positive learning experience. Peak Performance Buoyancy is no exception.
References from other students don't help either, because over 95% of the students out there are taught by the 95% of the instructors that don't know the finer points of diving.
This is why at this point in time (note the conditional there) the ONLY sure thing out there is the DIRF class.
