On this special GUE-focused episode of Pod Diver Radio, we head to a chilly Dutch Springs Quarry to sit down with Global Underwater Explorers training director Bob Sherwood and take a deep look at GUE Fundamentals—"Fundies"—from the inside. Bob explains what GUE really is as an organization, how the Fundamentals course functions as the gateway into the system, and why there are two performance levels within a single curriculum (recreational vs technical pass). He breaks down the 1–5 grading scale, what it actually takes to earn a rec or tech pass, and how the provisional outcome works in practice for divers who need a bit more time on the tools. We walk through the core skill set of a Fundies class: buoyancy and trim windows, regulator and long-hose drills, valve drills in singles and doubles, team gas sharing and ascent procedures, propulsion techniques (frog, modified frog, helicopter turns and that elusive back kick), as well as the standardized backplate/wing and long-hose configuration that underpins GUE training. Bob also talks philosophy: risk vs benefit in mission-oriented dives, why GUE keeps standards and procedures consistent from rec through cave and tech, and how team diving, fitness, and honest evaluation all tie together. If you're a current GUE diver, Fundies-curious, or just a skills-focused tech diver, this episode is a detailed, no-BS listen into how GUE thinks and trains.
