Instructors may have to alter some of the techniques and some equipment may also need changing to meet the individual's need. In some cases extra pool and / or open water training may be needed. In some extreme cases even individual lessons may be needed. IAHD believes that people with a disability should be in a regular class at some point in their training. Being involved with activities like scuba diving may even result in giving a person with a disability a renewed interest in life and provide positive and lasting benefits.
