True. Good point. Several agencies do offer Bubble Blower, Scuba Rangers, or some other variant of that at least a few years before the 10th birthday.

That advise is not about the market at all. It's about what the diver is currently using. If the diver were to use two computers with different algorithms, they should be aware of what the more conservative one is telling them. Mainly for that next dive. For example, if the diver's primary...

Keep in mind. Your situation is unique. None of the certifying agencies will even consider it before 10. Your sons had the benefit of instructor parents. I do partially agree. If we are talking about an 11 year old with limited water exposure, then a Discover Dive would be a bit much...

I never did a Discovery Dive with my kids, but both were certified young (10 years old). Their experiences, however, were a bit different. I absolutely had the desire that they would want to dive when they were old enough. I tried to foster interest via age appropriate books, videos, etc...

The regional differences here struck me as a bit funny. Around here, the local fire departments often get their SCBA tanks filled at local dive shops. But there are multiple dive shops around, so it makes sense that the fire departments probably don't need to have their own compressors.

Partially. IIRC, the dive flag was initiated by a group of scuba divers in FL as a way to alert other boaters that there were divers in the water. Requirements will probably vary by state, so what I say may be just applicable to Florida. A dive flag is required when divers are in the water...

Yeah. That's the distinction that I've been familiar with. Set price for boarding = charter. Passengers throwing in some money after to help isn't. This statement is in the Boat US article I posted above: "Passenger for hire" is defined as a passenger for whom consideration is contributed...

Forgot one. The most perplexing one for me was an anchor. I ended up selling it as it was way too big for my boat. Included was anchor, chain, and line. The line had been cleanly cut. Definitely not a break. So, we unraveled it and brought up the end of the line during the ascent. At our...

Not bipolar. And my thoughts as well. I see a great deal of benefit for a new diver to use AI. Having all the information in one place is one less thing to check. This can also be accomplished by a puck computer in a console, but then you have a bulky console and at times, the console may...

Yep. Didn't get the British humor. :wink: For sure, the very early iterations of AI transmitters were quite problematic. Most more recent iterations have been much more reliable. Suunto seems to have stuck with the nostalgia for some reason and they haven't fixed as quick as some others...

AI for a young diver is no problem whatsoever. Depending on the particular computer, it may actually be better. Both my daughters use AI computers. They did their training with an SPG, but as soon as I had enough transmitters, I converted their gear to AI. My first computer was actually a...

In the beginning of a dive, I came across a 2lb soft weight. Clearly hadn't been down long. Then a few feet later, I came across another one. Then I realize these must be mine. New BC at the time, and I had forgotten to zip closed the weight pockets. Luckily I found them or I might have had...

Shank. Yeah, those can get pretty heavy. Last one I recovered was a nice one that currently sits on the bow pulpit on my boat. 22 lb stainless plow anchor with about 20' of chain. I hand carried that up my anchor line. At the surface, my BC fully inflated was not enough. I now bring a lift...

Yes. That's true. I was absolutely thinking during the dive. But, you are correct. I have one of them that does allow that.

I saw that happen to my daughter (10 at the time) on one of her checkout dives. Another student accidentally kicked her and knocked her regulator from her mouth. I was right behind her, but wanted to see how she handled it, so I got closer, but let her do what she was going to do. The primary...

Just for clarification to those that may read this later. I think you meant to say you marked a bearing or heading. You can't mark coordinates with the Tern TX or any dive computer. Good to see that you like the Tern TX. I have been hoping for a Peregrine with AI for my daughters, but might...

This does not mean that any water got into the first stage. If the cap is the type that seals well, that seal will occur where the DIN o-ring meets the cap. So essentially, only the area inside the circle formed by the o-ring is sealed. Water can, and will, travel along the DIN threads up to...

Exactly. I do mail order some things, but my local shop is really quite competitive on many items. A while back I was looking to get some HP120s. I checked one of the shops locally during an annual sale they have. Price still looked higher than I thought. While there, I checked the price on...

Certainly appears that way. These tanks can’t possibly be worth the aggravation at this point. It is indeed odd. He has the tanks back from the original shop. Presumably, he’s had an opportunity to take them to another shop for a second opinion on the Vis. It appears that either that didn’t...

Several options, much will depend on your set up. My BC has a pocket with a D-Ring nearby. So, I have a bolt snap with a small section of line attached to the light. Light goes in the pocket, line is small enough to fit under the zipper when the pocket is closed. I attach the bolt snap to...
