It's an activity that lets you fly above the water.
But how safe are water jet packs?
Some people call them a jetlev.
SeaBreeze Hawaii in Hawaii Kai is the only company to use them on Oahu.
It's a jet pack that allows the user to fly by harnessing the power of controlled water pressure.
The state Department of Land and Natural Resources says the public has raised concerns about the jet pack, so it's thinking of coming up with rules to regulate their use.
"It brings together other ocean users that may be impacted by the potential use of the jet pack, the fisherman who are concerned that the operation of the jet pack in certain areas would have an impact on their fishing areas," state Department of Land and Natural Resources chair William Aila said.
"There's no more environmental impact from that jetlev that there is a jet ski and a recreational boat," SeaBreeze Hawaii owner Jeff Krantz said.
SeaBreeze Hawaii says customers go through training before using the jet pack.
Although the pack can lift someone 30 feet in the air, customers are only allowed to go as high as 10 feet, and an instructor controls the throttle.
A public meeting to discuss the water jet pack is scheduled for Thursday.
