Hi I have "hookah" dived since a teenager, mostly for gold diving. In fact very much like the new TV show Gold Rush White Water in fast mountain rivers and creeks. It is where a pump sends air down to you.
There is a revolutionary new super portable dive system from Brownies (BWMG), a pioneer diving equipment company that has been around for decades.
A video is worth 10,000 words and faster. It is referred to as hookah diving, but never this lightweight before, you can jog with this on your back, throw it in back seat or even motorcycle it, or take on airliner. Its battery powered and pumps air down to you, no tanks needed.
It will be introduced on Kickstarter Feb 1. I am an investor in the company. Have always wanted a product like this, and it will collect data for temp, salinity, turbidity and more effortlessly which will be big bene for researchers, archaeologists, treasure divers, and pleasure snorkelers will "baseline" areas as a side benefit as can be uploaded to http://www.projectbaseline.org/2016-expedition-overview for providing scientists with data.
Do not know if any prospectors here, but it is a game changer for that. Its knapsack like on your back so you can hike in rough terrain, then throw it in water and dive to 30 feet and stay down a long time.
