Well there is many things you can do extend your under water time. All of tables will help you by extending your dive. In general the best thing you can do when you are not in the water is to tray to do apnea walks together whit tables. By doing the table you will learn how long you need to breath up before a long dive or apnea walk. The more you practice the better you will become and you will be able recognize sings of you getting close to your limits. This is helpful for your safety when you are hunting alone there is nobody to help you if you get in trouble. So if you want to push your limits first practice on land and when you feel comfortable whit the results tray them in water but never push your limits in the water because an error can be deadly. So again i am sorry about my poor English but again never push you limits in the water. We are not doing this for records we are doing it for fun. It is better to come back whit no fish but alive.
