I would rather make the whole regulator by myself out of scratch in my garage than trust a Chinese knockoff high pressure time bomb but that is just me and my Chinese metalworking machinery :D anyway, the ATX40 with either a DS4 or DST first stage is a great reg and should be reasonably priced...

Yep those crazy cheap Chinese second stages are probably meant for DIY hookah applications where the whole point is being as cheap as possible no matter how unhealthy and dangerous. Making a second stage is very easy though if it does not need to be very high performance or reliable... I am...

you need the camera body, additional external batteries for it (the internal lpe6 batteries dont last long enough on bmpcc4k) , the large cfast cards or alternatively usb-c drives if you can fit them in the housing, the lenses (expensive and you may need couple of them) , the housing itself...

Almost every non-diving person I know of calls the scuba tanks "oxygen tanks" here and when corrected in the next sentence they call them oxygen tanks again. It can't be helped it seems :shocked: well, it was common to use surplus army oxygen tanks as scuba cylinders after the WW2 when they...

by Ursuit it seems. Ursuit customizes suits as well. You can ask them for details and how much an X or Y configuration would approximately cost. I believe there is local retailers in Italy as well who you can negotiate a good price with

bleeding would be the most potential problem with tooth removals I believe as well as the fact that the gum may be sore and keeping the reg in mouth thus being more difficult or at least a bit painful. it would take much longer to heal if you needed stitches compared to simple removal. Don't...

I believe the avalanche of problems which may ultimately lead to drowning is most of the time caused by the diver doing something wrong first which didn't seem like that big of a deal until it developed to something much more serious some moments later. Ignoring previous medical history or not...

I would preferably test one new piece at a time. with the suit first testing the fit on dry land and then in a pool and familiarise yourself with the valves etc. before going into open water. I would have the buddy with all known and familiar gear when testing new gear myself, then only one is...

I haven't seen the movie, just watched the trailer... some of them seem to have Ursuit suits, the logo patch is clearly visible on the shoulder. No idea what the blue suit is. the rubber drysuit might be a custom Loitokari suit though I am not an expert on this, just guessing because they...

yep that's why Europeans like the metric system and litres x bars instead of the cubic feet stuff. another thing is that your actual fill pressure is not exactly the same that would result the tank containing exactly 80cf or gas which makes the whole "tank containing always 80cf or 40cf of...

one of the warmest and most durable options could be an all-rubber drysuit with integrated custom made dry hood and possibly full face mask and all heated undergarments. some of the persons here use that kind of stuff for ice diving though it might be a bit too extreme :D If doing "normal cold...

those should be normal safety procedures for every dive, including all recreational dives. It is also much easier to check these thing on surface than underwater. anyway, how do you generally do buddy checks and does this person first check all by himself and says all OK and then buddies double...

they also mention it on their webpage. Teaching TecRec Instructor Overview | PADI it would be interesting to see the training materials. It definitely sounds like a course where one instructor just stitches up some training material he likes and then gets it approved and starts to teach cave...

I have been very happy with my ATX40/DS4 set. breathes wonderfully and has not have any issues ever. not super sexy or expensive looking but gets the work done :) there is not much practical difference between the apeks 1st stages other than house routing and number of ports. the most versatile...

The amps and volts and watts are getting mixed up a little in this thread :) the main point being still that it is difficult to fit enough solar panels in a sailboat to get enough watt hours per day to be able to compress the required amount of air for scuba purposes. If one would only use a...

would a small booster work for pumping normal air to the required pressures if you generate the low pressure working air using a small 12v compressor so small sized it can be powered from solar panels directly? would be very slow and a tad expensive and you would need to have custom filter...

in Europe they also sell "piggy tanks" which are steel tanks with much larger diameter than normal but the tank is also much shorter than regular tanks. the capacity is the same 12L but because of the shape difference the cylinder walls are little thicker to handle the pressure and the tanks are...

as I have seen people tend not to purchase the green Nitrox models unless required by law... it is more of a hassle to change different M26 tank valves to all the tanks and have different dedicated hoses and everything. the "nitrox reg" may also not be oxygen clean after you use it for a while...

I have very similar 3L eurocylinder tank with ps230 and pt450bar. but the shop sells them as 230bar tanks which would be more honest marketing I think. I am absolutely sure though that all the tech guys would boost it to 300bar on pure oxygen without any hesitation:D

I would consider shallow solo diving pretty much the same risk level as a bit deeper solo diving as long as you stay within NDL limits. Hookah diving would have lots higher risk levels than scuba though especially if going deep and if using a compressor hookah rather than surface scuba tank...
