The PROBLEM with buying a cheap hookah is this.
IS THAT A UNIT YOU WANT TO RISK YOUR LIFE WITH??
I REFUSE to recommend a life saving device made cheaply in another country. ALL I have seen have a 90 day warranty. WOW!!
Seriously folks. Water hunting is FUN and PROFITABLE in the right places but
GET CERTIFIED
I refuse to recommend anything else. Sure people can do it and not get into trouble. However, you are asking the wrong person for advice. One real good friend and two acquaintances died while detecting and WADING.

I have been certified since 1980 and I have 37 years of diving experience. Over 20 in murky water. I was on the search and rescue team in Utah when I was a cop.
I know this is not what anyone wants to hear, but this is all I can give. Sorry
