    Drysuit disaster from La Jolla to DC...!

    I too disagree on the suit for buoyancy issue. When decending with an empty BC/Wing, one will need to add air to the drysuit to prevent squeeze and provide warmth within the first 10meters (and again as the dive progresses deeper)...this air serves double duty as it also provides buoyancy. There...

    Just a lil help for a newbie

    10 to 15 dives still has you at the "inexperienced" level. I wouldn't consider anyone as "experienced" with less than 100 dives unless they are diving multiple times a week, every week and then I still wouldn't consider them experienced before hiting the 50 to 60 dive benchmark. You are making...

    Vertical vs Horizontal Perception of Distance

    I have had a few convesations with my daughters about this very topic when they were in the process of getting certified. Both were competitive swimmers and were very familiar with the horizontal distances of 25 meters (@82ft) and 50 meters (@164ft) as the pools they trained and competed in were...

    Just a lil help for a newbie

    My recommendation is to get a snorkel and play around in a pool until you are comfortable. After a few days when you are more relaxed in the water, switch over to a cylinder with regulator and just relax in the shallow end until you can breathe without issues. Unless you have a major overbite...

    Service technicians: are HOG regulators entirely serviceable with APEKS parts?

    You or your Apeks service guy should be able to source HOG service kits via the internet as the brand doesn't restrict sale of kits to end users. https://www.diverightinscuba.com/shop.html?q=HOG+service+kit https://www.piranhadivemfg.com/search/HOG%20service%20kits...

    Comfo-Byte for Apeks question.

    My preference is a custom mouldable regulator mouthpiece. I believe the last one I purchased was a Trident brand one. It was less expensive at the local shop I frequented while living in Belgium compared to the price at the Amazon link below but that is the product I got...

    Wanted Looking for a complete regulator set

    How is it that you are going to be working as a DM but don't have a basic set of gear to support this? What happened to the gear you had when you did all the diving necessary to become a divemaster? If are looking for a global brand that can be serviced in both Europe and the US then I suggest...

    Question Hydros Pro - Floatation Position on the Surface?

    Its neither an issue with the hydros pro or any other back inflate type buoyancy compensator. If you are used to wraparound jacket style setups, it may take a dive or two to figure out and be comfortable with back inflate/wing type BCs. After those couple of dives you will most likely find...

    Hello, I'm looking for divers to take part in my dissertation project.

    The danger of using a "discussion" forum to solicit input is that folks might actually "discuss" the topic within. -Z

    Hello, I'm looking for divers to take part in my dissertation project.

    From an operational risk management perspective, there is always missing information. Effective decision making with regards to risk management is to consider the information at hand and make the best decision for the scenario despite the fact there may be unknowns. At the naval war college we...

    Hello, I'm looking for divers to take part in my dissertation project.

    As a retired naval officer I spent plenty of time on ships in 25 knot winds and 8 foot swells/waves or more.....I don't care how big the dive boat is or how many crew members you have, that sea state is not going to make for a good or safe time on or in the ocean. As a dive professional, the way...

    Question Questions about Drysuit fins and air in feet

    Here is a website that seems to have all sizes of the original fusion boots in-stock: https://www.scubacenter.com/scubacenter_onlinestore/drysuit_accessories/Drysuit_boots.htm The price ($135US) is a bit spendy but that is what the regular retail price was/is for these boots: The boots have...

    Hello, I'm looking for divers to take part in my dissertation project.

    I am interested in what further information you would need to make a risk assesment in each of the 5 scenarios. For instance, the first scenario the sea state was such that I don't believe most shops would risk their boat and crew, and it would make for dangerous entry and exit....the...
