How much does it cost to get Scuba Diving License?

It is a certificate not a license. You get certified (trained) in the skill of SCUBA. Cost depends on the market in your area. Length of training will depend on the student and their abilities. I have certified students in as little as three days but that was three full days. I have seen classes offered for $200 to $600 per student plus some equipment purchase. Shop around and talk to your dive shops. I would not recommend a "presto" customized or two day class as this is a skill you should be well trained at. You only screw up once at depth. Think about it!
