Floating Gas Powered Units

  • The best choice for recreational diving due to the essentially unlimited lateral range of movement.
    • With a floating gas system, the divers easily tow the floating unit along with them, so they can move about without restriction in range.
    • In contrast, with the deck units (e.g., electric units and deck-mount gas powered units), the lateral range of movement is restricted by the length of the hoses. (Although it is possible to use hose extensions to lengthen any hose.)
  • Floating gas powered units can also be used as deck units when desired, by simply not inflating the float. The engine/compressor case has white rubber feet to protect the deck.
  • Which floating gas unit is best for you?

Deck-Mount Gas Powered Units

  • Primarily used for commercial applications in which the unit will be operated from a boat or other platform.
    • Used for a variety of commercial applications (e.g., boat and other marine salvage, marine construction/repair, aquaculture, marine survey, scientific diving, in-water boat repair/maintenance, etc.)
  • Sometimes used for recreational diving when placed in a dinghy or similar platform.

Electric Units

  • Often used by boaters who want a compact, lightweight system that enables them to dive under the boat when necessary (e.g., unfoul a prop, clean the hull, free an anchor, etc.).
    • Can still do a little recreational diving around the boat.
  • Also used for a range of commercial applications (e.g., boat hull cleaning, aquaculture, dock construction/repair, large aquarium work, pool maintenance/repair, etc.).
  • Electric units are quieter than gas units when noise level is a factor.
