Hmmm. I guess I won't feel bad having a third set of fins. I have twenty year old Mares Power Plana carbons and three year old Mares Superchannels. They are both negative but not tremendously so. I would consider a heavy fin since I am a bit foot buoyant in a drysuit but think I should modify...

Hi Folks, Anyone have an opinion about fins best suited for frogkicking? I currently use Mares superchannel (size regular) and old Mares power plana fins. I kick frog style almost 90% of the time since I feel it is more efficient (opinion, only) and reduces cramping in my legs. I'm going to...

2.5 x 1 x 3 is the size of the treadmill after folding it up and storing it standing up. Actually, it is likely 4 feet tall. 15 minutes on and off for a total of several hours of tumbling time is what I meant. They will be on a timer and I set it, then walk away and come back after it is done...

Yes, I looked online for many weeks and seemed to have found a motor that is 100% duty cycle but realize this is overkill (the motor costs was $150 and I still need to buy rollers, bearings, frame, tubes and rods. I figure I will run the motor 15 minutes on, 15 minutes off and 15 minutes on...

Thanks, that doesn't look bad. Just simple and to the point. I'm finding posts of people using even simpler methods such as hacked electric drill motors. No rush to get one set up but I have been muddling the idea for a year or so and getting impatient. I need to gather parts and put it all...

Just wondering if anyone has hacked a treadmill to make a tank tumbler? I realize a treadmill alone can be used as a tank tumbler (put it on it and add two bumper wheels to keep it in place.). I just don't have the space to keep a full size treadmill. My idea is to shorten the platform length a...

Thanks, I ended up ordering an Aeris AT400 to try out. I'll use Oceanic service manuals and parts for re-builds.

Hi Folks, Just wondering if anyone has had much experience with TUSA regulators and servicing them? I'm looking for a couple back-up regulators to use as stage or pony bottle regs (light and compact). On Eee-bay, there are a few people selling the RS-860 for as low as $120 but typically $150 or...

Thanks for the quick reply. On a side note: I'm happy with the Petrel. The improved streamlining of the Perdix having a similar screen (if not better) and smaller overall form factor would have been nice to have but I felt equally annoyed with my former Suunto Vytek (puck style) catching and...

Hi, I have a Petrel 2 and downloading logging dives onto two separate Mac computers. One is a desktop and the other is a laptop. I wanted to import dives from the laptop to the desktop(primary). I originally tried to import by going into the file directory of the laptop and copied the "swlogzp"...

In case you already know what the item is: The price is $160 includes shipping (regular USPS post). I am a selling a Dive Rite Primaloft undergarment, size small that was un-used and never in water. I purchased it hoping I would be able to fit in it but after walking around the house in it, I...

If you simply want a boot without having to ask an entire industry to make thousands to meet your needs you may have alternatives. Maybe try 3D printing using a material with high toughness. You may also try to machine one from a composite (fiberglass filled molded tube?). Using the K.I.S.S...

Thanks for the reply, It does make sense. If you are a NADCAP, ISO or some other Quality control org certified supplier, you may be either required to segregate material supply or test everything that goes out. I don't know the exact requirements but only guessing. Segregating as you describe...

Hi Jax, Can you please specify with numbers rather than making us read a large document from your link? I also could not find any hits from searching "purity" in that document, anyway. Just get to the point, please. On the other hand, here is a link that states "industrial grade" should be...

OK, I have an update related to keeping and re-using your own cylinders: There are a few folks at work that use a tremendous amount of gas but cannot tolerate even a little impurity above the normal specified amount. They keep their own cylinders and never swap out other cylinders when a new...

If you purchased your suit using a credit card, call the credit card company and see if they will support you to completely scrap the suit as "unusable" and a "total loss". Then throw the suit away or keep it as a show and tell sample of how poorly made and awful service BARE makes and supports...

(My opinions only) I believe regulator servicing is not tremendously difficult. New regulators are a little more complicated (at times) but still well within reach of a careful person. Vance Harlow's book is a must read since it compiles most of the information you need at one location. Download...

This discussion is familiar. Another question is whether or not oxygen is a significant contributor to narcosis. In a text I'm reading ("Recreational Trimix Diving", Kevin Evans) oxygen is stated by the Meyer-Overton hypothesis as having 1.7 times narcotic potential as nitrogen. The text also...

One last personal example to add. I purchased new cylinder valved for inert gas mixes as I mentioned earlier. It was filled with Argon/CO2, 90%/10% (used for MiG and wire fed welding). I wanted it re-filled at a small shop with 100% Argon and wrongfully assumed they would drain the remaining...

Thanks for the inputs. Yes, I am getting ahead of myself. 'Just a little overexcited since I dove the suit and didn't have the cold chill down my back and the gradual cold creeping up the arms like my wetsuit. I purge the suit perhaps too well (crouch down and pull open the neck seal to bleed...
