This program provides the skills and concepts required to safely and comfortably dive underneath surface ice. You will learn the special requirements for diving in an overhead environment, the techniques and communication methods, and the specialized equipment used for ice diving.

The East Coast Divers Ice Diving program opens up the frozen landscapes under the ice to experienced cold water divers. This unique specialty brings a whole new set of challenges to recreational divers. For example, scuba under ice places the diver in an overhead environment typically with a single entry/exit point. Therefore, the sport requires special advanced training.

Ice diving is a team diving activity. Each dive involves line tenders, dive teams, a safety diver, and a site supervisor overseeing the operation. Ice divers are tethered with a harness and ropes to increase safety. Of course, line tenders manage the ropes from the surface maintaining a connection to the dive team. In addition, they facilitate communication with the diver using dedicated pulls. Ever vigilant, the safety diver is ready to enter the water at a moment’s notice and has a dedicated line tender.

Site Superviso

An experienced Ice Diving Site Supervisor oversees the whole operation.

Are you interested in developing the teamwork and experience to explore the crystal clear waters under the ice? Come learn how to configure your gear, prep a site, tender lines, plan, and safely execute dives under the surface of frozen lakes. Indeed, it offers divers a unique look at our underwater world. East Coast Divers has knowledgeable instructors and highly experienced partners in Central New Hampshire. In summary, the ECD team has what it takes to deliver a thrilling ice diving excursion this winter.
