I found Pearl Divers, it was not easy 'cause its crazy. They write the street names in different ways depending of the person!!!! But finally I found. It is near Doha Clinic (little before in the street if you come from Ramada).

It is a scuba diving shop and dive center. They gave me the bussiness card of a guy:
Abdullatif Al-Naemi

It looks like they go to scuba diving each weekend.
Im checking prices and details, when I have something else I will share with you.

My colleague will come on 24th, so we will try on that friday-saturday - it will be his first time, so we will ask for "Sea Baptism" or "Discovering Scuba Diving" or whatever they call here in Qatar - it is just a little diving in very safe environment for people to check and to lose their fears.

Lets see...

InesM - vaya! una hispano-parlante. Y qué hace usted aquí tan lejos de casa? Se nos unirá usted a bucear? Experimentada buceadora, o como mi amigo, que quiere probar por primera vez?

War looking for peace,
is like fornication looking for virginity.
