Types of Diving -- Diving Bells

After snorkels, diving bells were the next successful method of increasing endurance underwater. These bells consisted of a weighted chamber, open at the bottom, in which one or more people could be lowered underwater. The early use of bells was limited to short periods in shallow water, but later bells became quite popular when inventors developed methods of supplying fresh air to the bell using barrels and hoses.
