Precision Diving: Beyond the Basics
Like Duolingo, but for Precision Diving: Beyond the Basics. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
For the part of you with thirty open tabs that never became anything.
A short one: 12 levels across 2 sections, about 24 minutes end to end, roughly 5 days at five minutes a day. It moves through Technical Mastery and Trim and Complexity and Crisis Management.

Key ideas in Precision Diving: Beyond the Basics
- A head-up position increases the vertical cross-section, creating massive hydrodynamic drag
- The Frog Kick's recovery phase keeps fins away from the floor to avoid 'percolation' or silting
- Propulsive force in horizontal trim is directed entirely backward, whereas angled trim wastes energy pushing the diver upward
- Modified kicks involve smaller movements of only the ankles or knees to stay within a tight 'profile' or 'envelope'
- Reduced physical effort lowers the respiratory rate and prevents CO2 buildup, directly decreasing gas consumption
- Thrust must be directed strictly backward to avoid disturbing the thermocline or visibility in overhead environments
- How horizontal trim impacts gas consumption and physical exertion
- Selecting the appropriate kick for specific environmental constraints
- The kick begins by flexing the ankles to hook the water with the top of the fin
- Lung volume acts as a 2-4kg buoyancy swing that can be adjusted instantly
- The power stroke involves pushing the legs outward and then pulling the knees back toward the chest
- Micro-adjustments are made by shifting the 'center' of the breathing cycle (breathing from the top or bottom of the lungs)
- The ankles must rotate at the end of the stroke to minimize drag during the reset
- Using the BCD for small, temporary shifts leads to 'chasing' buoyancy and instability during complex tasks
- The mechanics of a back-kick for spatial precision
- Using lung volume to offset buoyancy changes during task loading
You've tried the other tabs
Thirty open tabs. Four facts you actually kept.
You watched. You nodded. By Sunday it was gone.
One answer, then back to scrolling.
Eight weeks. You meant to finish. You didn't.
Tomo gives Precision Diving: Beyond the Basics the Duolingo treatment: levels, streaks, and quick quizzes that test what you just learned. That game loop is what the tabs above never had, so it's the one you actually finish.
Here's what playing it feels like
A real question from this course. Take your best guess.
Why is the frog kick preferred over the flutter kick when swimming close to a delicate, silty bottom?
