Question: What is the difference between a Dive Guide and a Divemaster?  Both RSTC and ISO describe Open Water qualification as an “autonomous level” qualification. ‘Autonomous’ means that the qualified diver DOES NOT REQUIRE SUPERVISION relative to the level of their qualification. Consequently, it should be appropriate for a “Dive Guide” to accompany them purely […]

Bungee Secured Finger Spool Here’s my approach to configuring a very secure, yet easy to deploy finger spool. It works well for overhead environment safety spool use, and is quick and intuitive to deploy, even in zero visibility. Originally posted 2018-11-05 06:10:15.

Scuba Q and A: Deep Diving Below Recreational Agency Depth Limits http://scubatechphilippines.com/scuba_blog/deep-diving-below-agency-depth-limits/ http://scubatechphilippines.com/scuba_blog/deep-diving-below-agency-depth-limits/#respond Wed, 07 Aug 2019 12:39:54 +0000 http://scubatechphilippines.com/scuba_blog/?p=1214 Andy Davis Technical Diving Blog

Scuba Q and A Question:   I was taught that “recreational divers plan all dives to be no stop dives” and also that most agencies consider 40m /130 feet as the maximum depth for recreational deep diving.  That seems inconsistent when my dive computer allows me to dive below 40m/130 feet and still stay inside no-stop limits.
