Well, I would definitely matter how the BMI was calculated. I think in your example BMI was figured from a height/weight table. That method assumes some typical dense body mass based on your height, and then any excess weight is considered all fat. If you're not typical, that method is...

First, thanks for doing this. It is an amazing spreadsheet. Just as a curiosity, could the 'Personal Buoyancy' be calculated from body weight and BMI (or fat/lean mass numbers) reported by some of the newer smart scales?

@The Chairman Do you know where I can rent a pony tank somewhere between Ft Lauderdale and Key Largo.

As much as I want to dive along southern coast, most places that everyone has recommended seem to have one boat per day, occasionally two on the weekend. Since I'm solo and only worrying about diving, I am leaning toward Key Largo for the exact reason you said... more dives per day. I would...

Pete, can you recommend any specific boats out of Two Georges Marina?

I've got 4-5 nights to spend in South Florida in November (not Thanksgiving). I will be alone, and want to do a bunch of diving. I can go anywhere from Riveria Beach to Islamorada. I need to get a good value, but I'm not without means either. Airbnb or Hampton Inn is my speed, so I can find...

Maybe I'm a little confused about what you really want to do, but I'm guessing that any reasonable tablet will work. For example, I've used an iPad Min Gen3 (circa 2015), iMove, and a SeaLife Micro while spending a week in Cozumel. My biggest problem was the wifi/internet, not my hardware. I...

Yes, this kinda hints at the other issue, like who is hiding what? Maybe hiding something with this specific event. But generally gathering any useful data might be difficult since local authorities in tourist destinations don't want to disrupt the tourist trade. We probably can't reasonably...

As we've all seen this happen many times, the media can blow things out of proportion, but they can also discover hidden issues or disturbing trends in events. If you don't know what I mean, google Satanic Panic and Watergate, which are two extremes cases (one on each side). A logical mind...

DOMINICAN REPUBLIC DEATHS: 7th American tourist dead in Dominican Republic while celebrating her birthday

Would trip insurance work for this type of cancellation? I'm not an expert, but changing your mind doesn't strike me as a valid reason.

Yes, don't be cheap on the instruction. That Hostel is really cheap, $10/day in a dorm bunk! If you're really on a budget, but want your own room, and there are two of you, try scubaclubcozumel.com. It is clean and nice, but not fancy. One large boat with lots of people, one smaller. Hot...

Yes, I disagree with forced upgrades too. Users should be left alone to choose. I have an older computer that I didn't want Win10, and it was very hard to avoid. My daughter accidentally accepted it one day and I was stuck. It turned out OK, and now I'm glad, but I was avoiding it for a...

The terminology 'wet' was originally because it included fuel. Whereas 'dry' means they pay extra for fuel. I'm not sure if 'wet' still includes fuel as well as a crew.

I don't have a watch or tables. I take my wife's computer as a spare, when she is not with me. A second dive computer isn't for increased safety. It is mostly a convenience thing, allowing you to continue diving if the primary computer fails. If you only have one computer and it dies, you're...

CocoView shore diving is great, and you can dive anytime you want. You could easily do 2-3 night dives, if you want to stay up that late. Someone told me the early morning pre-dawn dives are really good.

Rosevb: Welcome. Don't let us scare you away. Read past the banter and find the good nuggets of information. Here's what I think about your original question. Buy and use a dive computer. Use tables if you want, many do. The dive computer will make a GREAT depth gauge and timer too. Be...

I think the totality of the scubaboard community, and the skills and understanding of scuba herein, skews the perspective of many of its members. I work among a lot of extremely smart people. My coworkers all have Masters and PhD educations. Certain comprehension, knowledge, experience, and...

Use a phone book to find a Blockbuster and rent Tron on BetaMax. Ha, sorry, just kidding. Not trying to be snarky. As someone who has worked for large PC developers and with Microsoft, I hope that everyone really understands the huge cost of supporting legacy hardware in modern systems. I...

Definitely not most cars in the USA. Possibly a few years ago. Most new cars here do not have an option for a 'chip key' anymore. In fact, many of the new cars here have hidden mechanical door keyholes that are very difficult and cumbersome to access. You have do get down on your knees and...
