Standard open water class is 140.00usd instruction only.
Here's what you still have to pay extra for:
$40.00usd - two week rental (wetsuit, hood, BCD, Regulator, Suunto Favor Console, two 80cf tanks).
$35.00usd PADI crew pack (also we recommend but don't require them to purchase for themselves the PADI video or dvd set).
$80.00usd (cheapest)- $135.00(expensive) two tank boat ticket
$10.00usd passport photo
$75.00usd fee for seeing their doctor (medical) unless they have HMO.
Have all your own basic gear - mask, snorkel, fins, booties, gloves, knife, day-light, octo clip, slate. If you don't additional cost runs between $280.00usd for the cheapest stuff and $500.00usd for higher end.
So out the door costs for class is as low as $260.00 but can go all the way up to $880.00!
