Is Provo any good? Leaving in 12 days Sorry about the title.... I messed up :-)

Using the formula from TDI's Intro to Tech manual, p. 46... [(psi used/working pressure) x cylinder capacity] / {[(depth/33)+1] x minutes} If I go from an AL80 tank with a working pressure of 3000 to a steel HP80 with a working pressure of 3400 and everything else remaining the same...

Seems like I've done this successfully before but recently have had problems. If I click on "Quote" only, no response box opens up so I don't know where to type. If I used "Quote in Conversation." the response box opens up but the only two options are Start a New Conversation or something else...

Is there a reason NAUI is not listed here separately? Is it just the ones that support SB that get listed? My question was about the NAUI Instructor course. Is there a written test that is given to new students before they get very far into the course? I completed my online exam but the...

Has anyone tried it? Is it worth $24.95 a month? How to improve your buoyancy when diving.

Just went on a snorkel trip this morning and there was current. I didn't feel that I was quite as prepared physically as I've felt in the past but, then again, I'm getting older. I'm still swimming a mile 2x/wk but not with fins which create more resistance in the water to provide more...

Didn't know where to post this but was looking for a specific NAUI to post under. Guess there isn't one. Why would NAUI require this for an instructor course? Do other agencies require it? I can do it (and have done it many times) but am working on in Instructor cert now that I'm retired...

Turning 65 on Monday and have done lots of shallow dives while snorkeling. I've been interested in going deeper for years but never have "pushed the envelope." Do you know if there are specific contraindications for freediving after a certain age? I swim a mile in the pool 2-3x/wk and...

In the past, it seemed that you could only fly in and out of Bonaire one day a week. That seems to have changed. However, looking at different sites shows me pretty widely different prices. Anybody have any suggestions for flying out of San Antonio?

I'm already booked at Lion's but just discovered Sunscape. I suspect it would be hard to transfer my reservation with Expedia but I was wondering if it would be worth the trouble...? We've always liked all inclusives (Mexico), I don't know what kind of food is available at Lion's and I don't...

never mind.. I would delete if I could figure out how

My soon to be 7 y'/o granddaughter has been mad that she can't go SCUBA diving with Papa (me) and her dad because she's too young. I would like to take her some place where we can access good snorkeling from the beach/shore to help her make the transition. She's already a fish in the water and...

I know Sam Meacham who teaches this down in the Yucatan area of Mexico. If I can get one other student he will put together a class for me. I'm just throwing it out here to see if I can get any feedback. Here's a video of Sam that was sent to me recently. Cave Divers Explore the Yucatan’s...

I bought the DC2000 with the strobe and video light but only took the video light with me on vacation. I'm just trying to figure this stuff out as I go. If the Facebook link below works, why is the grouper so red? The camera was set on the underwater setting which probably played a role...

The other threads about the Litehawk configuration were closed so I had to create a new one. I was looking at both the Litehawk and the Hydros but there's a big difference in $$$. What justifies the difference? In watching this video, it looks like the main weights would be difficult to drop...

What would you suggest for Mac?

I'm not yet certified but am doing my reading so that's kinda where this comes from. Given my high SAC rate (not anxiety, have good cardio fitness - not asking for solutions) of about .67 as of last night, using the Rule of Thirds and the "dive factor" that will limit my gas available, I was...

I just got the 500 SE D7 yesterday and put it on a tank tonight to do my SAC rate. I couldn't breath it very easily and it was vibrating as I inhaled.

I've read some of the previous threads and responded to one but would appreciate some feedback. I read in one product review that you should get at least a +3.5 to read your gauges, assuming farsighted. I normally wear 2.00 to 2.50 "readers" depending if it's for a book or a computer screen...

I'd like to buy the whole series starting in 1968 (?) but am a little unsure about getting the real deal ordering from Amazon. I wrote the seller but am curious about why there aren't more options out there. One of my favorite things ever growing up was watching this show.
