Bubbletrubble, how will having this person "hire a private DM to watch over you" while on actual dives be any less productive than hiring a "good instructor/DM" in the pool? In both cases, he'd be doing something to enhance his safety, his fun, his skill level.
A pool presents a confined water training environment. It's safer than a drift dive in the open ocean off of a boat. In a pool, there are fewer variables outside the control of the instructor/DM -- no current, boats whizzing by, unpredictable floor topography, depths beyond recreational diving, colorful/unpredictable UW critters, other divers zooming by, etc. The student can focus on skills training. There is ample time to practice mask clearing, determine proper weighting, and get a feel for neutral buoyancy. On an OW drift dive, a private DM/instructor will almost certainly feel pressured to rush the student through skills training so that he/she can get to the "fun diving."
I mentioned pools and freshwater lakes because, having visited the Dallas/Fort Worth area, I'm aware that the only options for nearby scuba practice are pools and local freshwater lakes. My thinking is this: Why not invest a modest amount of time by practicing dive skills locally prior to a vacation? Yes, it takes some effort, but the comfort gained will pay off in a more relaxed dive experience while on vacation.
There's absolutely nothing wrong with hiring a private DM/Instructor for OW dives. However, I don't see it as an equally good alternative to taking a scuba refresher course with a good DM/instructor prior to the vacation.
bubbletrubble - just curious - where are you getting your information?
Personal experience.
How many students/new/infrequent divers have you trained?
I haven't formally trained any divers. I'm not a certified DM or instructor. I have never represented myself here on ScubaBoard as anything more than a recreational OW diver. Although I don't hold
any professional diving certifications, I
have dived with many novices and I have shared space on dive boats with vacation divers who presented a danger to themselves and others. My previous post was an attempt to keep the OP healthy and happy on vacation. Nothing more.
FWIW, I don't own a scuba business. I suppose that's why I have the freedom to suggest a non-diving alternative. No financial conflict of interest.
That being said, rather than attempting to discount my recommendations by pointing to my lack of dive pro qualifications, why not offer up a differing opinion?
To clarify, I have nothing against vacation divers at all. I think they can dive fairly safely given the proper investment in preparation.
Your post reads as if you are an authority on the subject (providing inaccurate information), yet according to your profile, you hold an AOW certification.
I'm not an authority on the subject. I never said that I was. The OP is free to take/leave any of the advice that I offered.
Some people do not have the opportunity to dive except when they are on vacation - and in fact, vacation divers account for a VERY LARGE percentage of the diving population. I agree, a private DM is often necessary for the first day or possibly more - but your over generalization is erroneous and you really don't have the experience or training to make the kind of statements you are making!
If vacation divers comprise such a large percentage of the diving population, then shouldn't dive pros be recommending that such divers obtain scuba practice
prior to the dive vacation? What kind of experience or training should I have in order to make these comments? I think you are misinterpreting my comments as vacation diver bashing. That's not at all what I'm saying.
I have seen newly certified OW divers that are FAR BETTER divers than many DM's and Instructors I've seen in the water.
Me, too. There's a simple explanation for this. Newly certified OW divers have just exited formal training, so the material should be rather fresh in their heads. Having trained with a good instructor, such novice divers are a joy to dive with. DMs/Instructors with poor skills are probably just out-of-practice divers (I hope). As you know, the title of "DM" or "Instructor" can apply to a person who earned the certification a long time ago but who hasn't been in the water recently. I would think that anyone who went to the trouble of getting a professional certification would have the sense to practice scuba skills prior to conducting OW dives.
I've also seen divers with hundreds of dives bounce around the reef and blow through their air faster than those who dive more than once a year.
I've seen a few experienced divers (100+ dives) who demonstrate pretty poor buoyancy control. I'd like to think they are just out of practice, but it's certainly possible that they never learned how to control buoyancy in the first place. Sad.
Many factors influence gas consumption. Being comfortable in the water is just one of them.
A higher rate of gas consumption alone is not always an indicator that the diver is out-of-practice or inexperienced. Some people have bigger lungs. For whatever reason (feeling cold?), some people choose to kick a lot during a dive. Current can vary with depth, and it's easy to see how spending significant time at a depth where high current is present might lead to a high gas consumption rate.
Based on reading some of your posts, I would agree with you that you do appear to be a control freak.
I'm a pretty risk-averse person. I tend to educate myself on something before I jump in with both feet. In any sports endeavor, I value properly directed practice.
In a leisure-time activity which carries risk of mortality/morbidity, such as scuba diving, I prefer to assume personal responsibility for my own safety. Others may choose to approach the sport in a different way.
