Immersionfreediving.com This video was shot during Immersion Freediving 3 day PFI Freediver course. Average student does a 2.5 - 3.5 minute breath hold and a 60ft dive. Students are tuaght how to properly equalize using Frenzel during my exclusive Skpe equalizing session before class even starts. This course consists of 7 hour of classroom, 6 hours of pool work and 6 hours in the ocean. Twice as much as typical 66ft courses on the market. 2 - 3 courses a month in Fort Lauderdale year round.
