I am not a doctor. But I have seen people diving with a stent, so that would not be the problem. But I don't now if there are other things against diving. The age, 72 is not an age that it means you are too old for diving. I have seen older divers, till 89. It depends on how fit you are...

First, what is a healthy bmi? There is no single healthy bmi. The bmi <=25 is healthy is developed for the western white man with a length of 1.80m. This means that if you are a woman it is already different. I am a woman of 1.82, so longer than average. I have never had a bmi <=25, as if I...

I use flexhoses on a lot of regulators, but NOT on my longhose. It is a floating hose and that is the problem. It can get behind your valves. Otherwise, some flexhoses are quite rough and can damage a neckseal. I like colors, so have them in a lot of colors on stages, as drysuit inflator hose...

Yes I mean that. We call that here in the Netherlands a deflator of 'uitlaatventiel'. So maybe it is a little bit a 'dutch-english' word. Argo Deflator voor dry suit Here it was that. Have you tried HD latex seals if they don't leak?

Ok, this will be a long long answer. But I have to write. I have to react about 3 things: experience, risks when teaching and helping others. I have to react first about the 2 years of experience. I see here a lot of opinions as this is impossible, not enough experience, blabla. But we don't...

I had the same with an almost brand new suit. And it turned out it was the deflator on the left arm. But now I can replace seals with the smartseals in less than 1 minute ;) I have replaced the seals several times with new ones, cleaned ones, etc, but the leak came from the deflator. With...

If I swim, I am very bouyant, to get under I have to swim very hard. So this does not work for everybody. In fresh water to do freediving I need 3kg of weight, in salt it is more. When I dive and need to do a negative Entry, I don't fin down, I just let me go down. This does not cost any...

Why are you wearing gloves? Is there something dangerous to touch it with your skin? :wink: And did you test it under water? Did you make a video of that? I am curious about its performance under water.

No, and I won't do it for myself. The reason is that I am already a full cave diver (and instructor), and when I did the cave diver course, there was no advanced wreck course. The cave diver course was the highest level you could get for penetration. Then the course was written and divecenters...

Exactly. But now it is waiting till someone writes: 'Do a course, then you will get the answer, you don't know what you don't know'.

I know some divers that need 15kg of weight in winter when using a drysuit+ 490 grams underwear+200grams heating system. But then this is not the water were the Avelo is designed for as it is written warm water, wetsuit. But on average in drysuit it is 10kg with a steel tank on their back...

I completely agree. I don't need any expensive instructor if I want to buy or try sidemount equipment (it is optional), and with a good manual I am sure I can dive it without any problems or difficulties. I need 5-10 minutes maybe to get a proper weighting and then you can go. You also don't...

Yes, I don't want unsharp pictures of course.

I never heard that oc divers don't buy enough gas. In Germany it started: they said they don't earn enough from ccr divers, so that made a minimum price for a fill of oxygen or trimix. They said they have to screw in the same hose for filling, so it is a difference if that action will earn for...

I never did a photo class, but I think I know where I am talking about, have been to the world championships underwaterphotography. Yes, that setting is the best. It has the maximum distance (from narrow distance to infinity) to use it, but the biggest chance for shunting. The 0.4 is for...

I have the 60mm lens (I never use it), the 45mm from Panasonic (my favorite on my olympus camera's), and the 30mm (sometimes in use). The 60mm is a pain in the ass to find your subject sharp, it starts shunting all the time in dark waters. The 45mm and 30mm are way much faster. With the 45mm...

If you only want to go to 40-45m, then you don't need trimix in most cases. And for sure not a ccr. It is nice to get a trimix cert that you can dive trimix if you really want, but there in a real world you won't do trimix diving on such 'shallow' depths. A ccr is a nice tool. I also have 2 of...

I will put some oil on the fire. The problem with the ow cert and also aow is that they state you are allowed to go to 40m, but not trained for. And here the big big problem starts with divecenters. They don't think you can do the training on your own. In every sport you can do and progress as...

I have seen this watch today for the first time, including a tankpod. It is quite small. It is nice that you can see where you have been diving (it tracks the way you take). But it can only be used to 60m (7 bars). So then it is a very limited watch with dive options. This means it is no...

AOW is only 5 dives, so 2 days and you are ready. This is the easiest way. Tell them you want to do the easiest way and it will be no problem. Do it somewhere were they only do shoredives, this will reduce the price. Officially an ow cert is already a 40m cert. Nobody tells you, but you can...
