The SETT runs sessions:

At weekends: AM (09.00-12.00) and PM (12.30-15.30)

On Wednesday evenings a session (18.00-21.00)

The cost is £35 per diver and includes a discount ticket for the Submarine museum.

All divers must be qualified to dive to 30 metres

All prices subject to change without notice.

A minimum number of 10 divers is required for each session (maximum 14), and at the weekend both sessions need to be booked for the day to go ahead.

Groups of less than 10 can be accommodated but may be placed on a waiting list until spaces become available. When your booking has been confirmed, we will require a non-refundable deposit of £15 per person to secure the booking.

Provisional bookings will only be held for 10 days. For a full session booking, a non-refundable deposit of £175 is required. The balance is to arrive at our office 14 days before the dive, regardless of when booked, along with a fully completed booking form. This must list the names of all divers and registration numbers of vehicles.

Bookings can be made either by post, fax or phone.

Cancellations must be made a minimum of 7 days before the dive. In this event, another date can be arranged at the management's discretion. No refunds will be given.

Although unlikely, the dive may have to be cancelled due to operational commitments by the military. In this unlikely event, the management will liaise with the divers to arrange an alternative date.

We regret that due to safety considerations we are unable to accept disabled divers. In the event of a fire the only escape is down 10 flights of very steep stairs.

If you have any Non-British nationals in the group, we will require their details 30 days prior to the dive for security clearance, as we are diving on a military base.
