Precision Diving: Beyond the Basics
Move from recreational limits to technical mastery by refining your trim, gas management, and situational awareness in high-task environments.
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.
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

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?
