Scuba divers generally benefit from a simple, streamlined snorkel that is comfortable to use and does not create unnecessary bulk. Common choices include traditional open-top, semi-dry and dry snorkels. The best option depends on how frequently you snorkel at the surface and your preference for simplicity versus splash protection.

A dry snorkel uses a mechanism designed to restrict water entering through the top when submerged, while a semi-dry snorkel uses a splash guard to reduce water entry at the surface. Traditional snorkels have an open top and the simplest construction.
