An O2 sensor actually creates voltage when exposed to Oxygen, Looks like a 128X160 1.5" screen. Have one on order but to be honest a single color screen will convey the info just fine for an O2 meter. His build is geared more towards tec diving. The .96 screen really isn't too bad when you...

Very nice, still waiting on a sensor to come in so had to build a voltage divider to start tinkering (was told right now there is at least a 6 week wait due to manufacturer's shifting production to health field devices). I know for tec divers the higher ppo2 will be desirable but I am looking...

Sounds like the resistor could be bad, do a continuity test with it and see if it shows open or not and then see if the resistance is correct. Also depends on which version of a sensor you have. Teledyne made one that had a higher output version called the R33 that was used in some readers...

This is exactly my thought. Use a credit card and as soon as you are through customs dispute the charges or report the card stolen. That or pack your credit cards and hand them a prepaid card with 5 bucks on it and tell them the bank must have something messed up because you are out of the...

So I have been trolling for a while trying to find something I can rebuild myself but isn't going to be a major pain. I came across a MK20 with a G250 set ended up paying 110 shipped and tax. I don't think it has a gauge or console with it but have my eyes on something though they didn't...

Couple simple observations here. First off if cruise ships are dumping crap they should be fined at ever increasing amounts until they can no longer afford to commit the infraction or are driven out of business. They take in money and turn a profit they can pay fees to do things the right...

Ok so not as much need to worry about it then I assume. Going to pick up some stuff to make some weights tomorrow before I head over to try it out. Will take me a bit to make the weights but I figure 45 for 25 pounds of lead shot is a lot better than paying about the same amount for 10 pounds...

Thanks for the info. Do yours velcro and clip in or just clip in? I believe the one I have is the QLR2. The velcro itself seems pretty stout but I can imagine in the right position it could come undone.

Yep it fits just fine. Glad I got the weight pockets with it then too. I looked at the bag it came in this evening and the BCD itself originally sold for 475 and the Air2 was probably around 250 from what I can tell but I know everything is older and used. I think the BCD was a 1998 model...

Picked up and Oceanic Isla BCD with integrated weight system and the pockets included but no weights. Looks like it was barely used to be honest, no fading at all that I can see. I know it's marketed towards women but being a heavy guy I am not too worried especially as it's just black and...

Well got my good cert card in the mail yesterday. First one had a DOB of 1931.... I talked to my instructor and said "I know I'm old but do you really think I am that old?" We had a good laugh as who knows what happened. Was given a dive mask with an integrated camera and picked up another...

Thanks everyone. I did my final pool dive and exam last night. Instructor said it had been a long time since she saw a 100% on the exam. I will be doing my open water Saturday and Sunday morning. I am going to try and get deep water and Nitrox done before October as it looks like I have a...

Started training last week and have two training dives in the books. Have always wanted to learn and get into the hobby. What finally kicked it into gear was my wife passing away. We were married for just over ten years and I know that I have to get out of the house or I run the risk of just...
