2.   Developing neutral buoyancy skills.

3.   Enable planning and executing tasks underwater safely.

The InnerSpace Specialty will be a one day course with a lunch break.  You will need to bring a set of dry clothes to change into while in the lodge.  Cost for the InnerSpace Specialty is $395.00 per person.   For those who plan an overnight stay with us your cost is $295.00.
