Whether you go on to full technical training or just come out a far sharper recreational diver, this course pays for itself in the water.\u003c\/p\u003e\n\u003c\/section\u003e\n\u003csection style=\"background: #f4f7ec; border: 1px solid #e6ecd6; border-radius: 16px; padding: 30px 34px; margin: 30px 0 8px;\"\u003e\n\u003ch3 style=\"font-family: 'Quicksand',sans-serif; color: #14295f; text-align: center; font-size: 30px; margin: 0 0 12px;\"\u003eLet's be clear about one thing\u003c\/h3\u003e\n\u003cp style=\"text-align: center; color: #3d4756; font-size: 22px; margin: 0 auto; max-width: 860px;\"\u003eThis is not a certification course.
