The only hard part if you have any leg strength will be equalizing your ears. 18ft is deep enough to potentially give you problems.

going slow doesn't help equalizing as well as stopping doing a valsavla maneuver and continuiing down...Originally posted by: MrScott81
isn't it better to go down more slowly to give your ears time to adjust to the change in pressure...If you can hold your breath for that long I would do down slow (saving energy too) and thus give your ears time to adjust....I know if I go down below 10 feet my ears bother me too much.
