About Refresher at Gilboa Quarry

Have you been out of the water for a while? Want to go over the skills and feel confident in the water? Some dive operations may require divers to have logged a dive(s) within the past year.


Our staff will work with you at Gilboa Quarry (3763 Old State Rte 224, Ottawa, OH 45875) on skills until you are confident again.  The Refresher course usually takes about 90 minutes and will review the 24 skills learned during the Open Water course. Our instructors will also focus on areas you would like to polish.


*Gilboa Quarry has a dive site entry fee of $30 which the student will be responsible for. Gilboa is a CASH ONLY quarry.
