DirDirect is a world-leading online dive shop run by Underwater Explorers based in Portland, Dorset, UK. Underwater Explorers is a dive centre with a striking difference. It was born out of the concept of "Hogarthian" diving, safe and streamlined equipment configuration, using the most robust products available for recreational and technical diving -- but at the same time, keeping it simple. It is based on the concept of "less is more" in diving and acts as an equipment outlet, training facility and source of sound advice.

Thank you for the excelent service and reasonable prices! I will highly recommend your store to my friends.
