To be a successful innovation in scuba, you need to hit a couple of requirement. First, it has to markedly improve either the diving experience, safety or both. Dive computers markedly improved safety and extended bottom times-it’s a hit. BCD-improved safety and with the addition of LP...

Looking at how the Avelo works, I have a couple of questions that seem significant. The primary one is gas remaining. The system automatically corrects buoyancy by adding/ removing water from inside the cylinder, changing the volume of the gas in the bladder. A standard tank has a fixed...

I am not clear why Carbon fiber tanks would be of interest. You need to displace the density of the tank and air. The big advantage of steel over Aluminum is that steel offsets the extra lead required to make tank sink. Also, you may want to check with SeaGate about the limited life span of...

I absolutely have a half arsed opinion, because I have not had this system in the water. It is pretty common in diving to poo-poo the new. Not having tried it, that may well be what I am doing. My opinion is based only what I’ve read here.

I saw where you the OP went on an excursion and brought 4 extra battery pack. A bad connection to the battery could result in the loss of the dive, the battery and the unit until it can be serviced/repaired. In water drag while diving in the tropics has not been a issue I have felt strongly...

just getting around to this thread. I read some of the more recent comments about down currents and the initial description. To really be adopted by the dive community, equipment needs to have a killer app. or some significant advantages over existing technology (Nitrox, integrated weights...

You are still getting banned....

Congratulations Pete!

Fin size has never been a problem for me and I wear a 15. Dry suit boots were an issue, but I was able to get pair of size 16 Hollis rock boots. They may be discontinued. Most open fins come in a 2XL size. I don't even consider buying a close foot, those are almost guaranteed to not exist...

Her mask is upside right.

As I understand it, the urge to breath has little to do with the level of O2 and everything to do with the amount of CO2 in your blood. I was wondering why you would try to hold a non-required stop when out of air. Safety stops are a nice thing to do, but you are unlikely to suffer any...

I travel with my regular open-heel fins and use booties, which are much better on hot or sharp surfaces. I also have a neoprene socks that I really like a lot. They stretch over the foot, so they prevent chafing under almost all circumstances. Wet wool tends to bunch and sag and won't compete...

I'll mention this because it has yet to be explicitly stated. Ditching lead is something you do to stay at the surface. You should be able to swim your rig up. Once there, you can make a decision on whether you can stay there. If the conditions have gotten much worse, or you realize you are...

Always plan your configuration as if you were going to have to swim home. Boats can lose you, currents can carry you, you can miss read a compass bearing. Ditchable lead is your redundant buoyancy and is bullet proof reliable.

Why I would be interested in buying a used product with a known defect and the explosive force to dismantle a car is beyond me. Weirdly, these are often the same people that go on about how important “life support” equipment is…

It's not like AL 80 tanks are a rare vintage find. They are common and cheap as dirt. The extra testing isn't worth the money or the trouble. Plenty of divers buy stuff new when they get certified, hardly use it and want to get it out the basement ten years later.

I am all set as soon as I put my hearing aids in the charger. It is a little scary how little I can hear (other than the tinnitus)

if the foot pocket were to long, you might feel pressure on the top of the foot. Numbing in the toe makes me think the heel is too tight. I would loosen the heel. 3mm should be plenty of padding to avoid chafing. You might want to borrow some fins to see if you can find some that are more...

It depends on what type of trip it is. If you are going to be doing challenging dives, you need a good dive buddy. If you are going to be puttering around reefs and sharing a room, a good companion. Easy on the eyes and easy virtue...

Why they had to charge you $300 to announce they couldn't get parts is beyond me. They should have should have just given it back and said they could no longer service it without doing any work on it. Charging you for work they should have determined they couldn't complete is bad business...
