It seems to work OK, but I can't find any place locally that sells the "bump gas" that is used to test it's accuracy & calibration. Using it is easy enough, but the calibration instructions are not the easiest to follow & it's not that hard to bump a button & accidentally end up in the cal procedure. I bought my first one here in 2019. It just died from a leaking battery. I'm looking to get another one. At this time, I think that I will likely get the same one again. I see that DGX now includes a little blue plastic piece that is new to me. It may make it easier to get a good reading from a tank.

I have used this back plate and wing for two years now in both fresh and saltwater in the US and Asia and it has held up perfectly and with no issues. Easy single tank use without a tank adapter. I like the adjustable harness system. I would buy it again without even thinking about it.

This dive gear bag is great. It holds as much as they say it does in the description with no problem. It makes it nice and compact compared to other brand oversized mesh dive gear bags. It seems quality-made and should last a long time. I plan on buying a second bag on my next order.

I have been diving with the XTRA Regulator for over a couple years now. This reg is AMAZING! The breathability and adjustability was a massive jump from the first cheap regulator set I bought. Originally these were just to help bridge the gap between the very cheap set until I could try out some more premium options and decide on my investment. I have since found myself buying another set for my partner and recommending these to every diver I meet. Admittedly I was worried what other divers, instructors, and mentors would think seeing a whimsical gear icon on my purge valve instead of the goated A or S. Would these immediately flag me as a flight risk? Sparking many conversations and even getting a couple head tilts, at first it wasn't exactly a confidence builder. After several dozens of dives this regulator has proven itself time and time again. So when I took my deep diver ticket and the instructor said you know we are going to 130ft and specifically pointed out you should only use reliable equipment at those depths I said "you bet I trust my life with these". XTRA balances air perfectly at all depths I've been to and has no problem supplying air whether I'm fighting a current or just chugging my SAC rate up. We've taken these things ice diving and we were literally the only ones whose regulators did not freeze or free flow. So if you are on the fence about buying a value priced, high performance regulator, look past sneaking marketing, or paying a luxury tax. I truly believe every piece of equipment you use underwater needs to be personally vetted and tested and that's true for any brand. I have tested many different regulators, I'm not going to say its the absolute best but given its price point, functionality, serviceability and reliability it will be what I primarily dive with.

I was skeptical of the size but for the price I figured I couldn't go wrong. I was pleasantly surprised by how much I can fit in it! DGX BPW, full-size fins, 5mm wetsuit, 2 masks, reg bag, and a bag of miscellaneous accessories. Still haven't taken it on any dive trips, but the zipper definitely feels heavy-duty.

For its price you absolutely can't beat this duffel! As it claims, holds an entire single tank backplate and all the accompanying kit.
