The 2300-F Floating Dive Unit is a battery powered electric snorkel that allows 1 or 2 divers to “float” a fresh air-supply along the surface of the water while they enjoy a safe and comfortable underwater experience below. With a light quick-release harness and no heavy tanks to carry, everyone including kids and grandparents can feel comfortable. A Soft Blue Hose bag is included. This two person float unit easily attaches to an external battery for Deck use. Not suggested for boaters if storage is limited. NEW: This unit is able to be switched from Two person mode to One person mode in seconds. This reduces power usage by 7 Amps. Also, this One Diver mode can be used if Two divers are in Shallow water. NEW: Our float units have a larger battery case for the use of larger battery sizes, allowing for additional dive time. Maximum Battery Size: Length: 8.99", Width: 5.47" and Height: 8.66". Recommended Battery is the Interstate DCM-0035. Check www.Interstatebatteries.com. We recommend Interstate Batteries as these are "Air Transportable".
