If you want each of you to monitor both of your tank pressures simultaneously while at the 30ft distance, the new MK3i and T2 would allow that (with +/- on the actual effective distance YMMV) ... plus the MK3i /T2 also has some new messaging capabilities between divers. However to get that...

Drifting now... Glycerine is mostly used today as the liquid dampener in gauges but in panel mounts on compressors where the gauges are going to be mounted where they will be exposed to heat I prefer mineral oil. The two are not miscible... if you are topping off and uncertain what it is...

Mineral oil is placed in some types of gauge housings to dampen the needle movement due to vibration where the gauge is mounted in a panel on machinery that vibrates (for example, compressors). Submersible pressure gauges used in diving do not require dampening and thus I've never seen a oil...

Opps... No, the XTX40/XTX50/XTX200 is not discontinued. https://www.divegearexpress.com/library/product-tips/identify-apeks-xtx-series-regulators

No, the XTX40/XTX50/XTX200 second stages are not discontinued. It's in the 2024 price list, and they are now listing the individual stages as available to order as well. As a guess, this is an issue with their website maintenance... nothing more.

See this rabbit hole... Calculating SCUBA Cylinder Capacity | Dive Gear Express®

Hmmmm, If we are going to be pedantic: While an LP85 does hold a Z-factor adjusted 81 cubic feet of air at 2640 psi, you can't use that pressure ratio adjustment and then apply another Z-factor adjustment. Start with the water volume.... Ideal capacity calculation based on Faber LP85 water...

As a retailer of dive masks, we frequently deal this issue. Dive masks should not persistently fog if the glass is reasonably clean. A more illuminating question is "WHY does my recently purchased dive mask persistently fog unless repeatedly treated with some kind of defog ritual?" The...

If you haven't heard the news, UPS and the Teamsters Union reached a tentative agreement on the 25th (which still has to be officially ratified by the 300,000 UPS workers, but there is no expectation it won't be.) This means the possible Aug 1, 2023 labor strike at UPS and subsequent...

Dive Gear Express ships via USPS, UPS and DHL name carriers for paid shipping options, as well as including some last mile services from 3PL's for our free shipping offers. We are following the potential strike closely but the reality is that 6% of the entire US Gross Domestic Product travels...

The original Shearwater Peregrine was announced in July 2020. In May 2023, Shearwater announced the Adventures Edition Peregrine in both light and dark versions that differ only in cosmetic styling from the original edition. The original edition has a black case with a blue inner display bezel...

As you say, it's the burst disk.

The valves for $50 were bundled with the aluminum cylinders we buy, but were not used. The cylinders are 3000 psi service, so are the valves. They can't be used on higher pressure cylinders.

Because our landed cost on the modular valves trippled.

Our long time customers know we have done this before, but not for a long while.... We have dropped the price on surplus first quality Thermo Pro standalone valves to TWO Valves for $50, or essentially 56% off. We'll include the inserts so perfect for both Yoke and DIN regulators. The...

Let's see if we can "crowd source" an answer to the following question: In the picture below, if "S" is ScubaPro Air II, et.al. and "A" is Aqualung AirSource, et.al. then what is the "?" post found on? Please no guessing, if you aren't reasonably sure, please don't guess. The threaded base on...

The average American reads at a 7th to 8th grade level. Writing in a clear, concise and logical manner is difficult. 40 years ago I worked in the broadcast TV industry, and among other things developed computer software tools to assist in the preparation of on-air scripts to be read by our...

It will work fine. Since you don't know the history you should have it serviced with an O2 cleaning. However, from a purely financial point of view it might be more cost effective to consider this... https://www.divegearexpress.com/dgx-first-stage-regulator-w-opv-and-hp-port For well under...
