US-based Scuba STAR Network is running the survey as the latest in its regular line of bi-monthly research into equipment and diving activity generally.
"The process of maintaining orientation and getting around in the underwater world can be a challenge, but is essential to safe, stress-free diving,” says Scuba STAR. “Despite their training, divers sometimes become disoriented on a dive, and must surface or take other steps to regain proper orientation and return to the shore or boat.
“Our April/May 09 Safety Survey is designed to explore the issues of underwater navigation, including the types of navigational techniques and tools used by divers, and the difficulties they occasionally encounter.”
Scuba STAR aims to help recreational divers go about their sport in as safe a manner as possible - and to influence, where necessary, equipment manufacturers, trainers and others in a bid to improve diving products and techniques.
Its survey results are read with interest by industry insiders and, as such, carry influence with some of the industry's key decision-makers.
The online survey questionnaires can be completed in minutes. Respondents are assured of anonymity, and final reports are published on the websites of both Scuba STAR and DAN (Divers Alert Network).

Reports from previous surveys can be viewed at the site, and some appear on Divernet. Divers can also share their experiences on any safety-related subject by using the organisation's Anonymous Reporting Form.
Data is used in the compilation of Scuba STAR's Annual Safety Report.
