The current record for the longest continuous submergence using SCUBA gear was set by Mike Stevens of Birmingham, UK at the National Exhibition Centre, Birmingham, UK during the annual National Boat, Caravan and Leisure Show between February 14 and February 23, 1986. Mike Stevens was continuously submerged for 212.5 hours beating his own previous record of 121.5 hours. The record was ratified by the Guinness Book of Records. Mike used a standard regulator and mask and wore only a t-shirt and swim shorts and an 8 pound weight belt, he had no surface breaks during the 212.5 hours. A team of divers attended Mike throughout the dive. The team was led by Diving Officer Trevor Parkes. The dive raised £10,000 for the Birmingham Children's Hospital from donations by the public.
