Blacktip Tech DPV/scooter, in great condition with a long list of improvements. It currently sits neutral and trim in saltwater, and has a 3hr 20 min runtime at 45m/min (recently verified in a rinse tank). Comes with: - 20Ah battery pack (built by Next Stage Gauges Next Stage Gauges - Cavepack...

Suex XJ-S scooter, very lightly used, excellent condition. 10 full battery cycles and 20 hours on the motor, so everything still on 100% condition. Comes fitted with a custom T-handle, Suunto compass unit in a custom housing, and stand. Also includes all the standard accessories, original...

I once made weighted drysuit socks, mostly for the entertainment value, but they were definitely not DIR approved. I’d love to hear the real justification as to why adding weight to fins is fine, but weight on your ankles is bad. Where’s the dividing line? Would metal plates in the bottom of my...

Starting a thread for anyone interested in Apeks' new 1st/2nd, the EVX 200/EVX Tungsten. Description and images that I scraped are in this post, but to summarize: Looks quite a lot like an XL4 second stage with a redesigned purge cover. Double-swivel hose will anger the DIR crowd but maybe make...

Managed to dig up the full spec and a couple more images. Looks like 1Q25 release date, I'm ballparking $849 US for the 1st + 2nd stage. Images and text are off a publicly accessible (but unlisted) CDN bucket, so I would expect it to be announced in the next couple days. EVOLUTION OF...

Little bit of digging around found this heavily pixelated image. Looks like a whole bunch of dive shops accidentally broke embargo. 2nd stage looks (to me) like some kind of XL4/MTX mash-up. First stage looks very interesting though! Nice hose routing for single-tank long-hose, potentially.

It's ubiquitous because it's affordable; it's affordable because it's technology that has remained unchanged since 1995. The lack of features (compared to the Garmin) doesn't intrinsically make it reliable - the signal can be blocked much more easily, it's far more prone to interference from...

Garmin doesn’t, but it’s the kind of possibility opened up by its transmitter tech. Garmin’s transmission protocol has much more range and data throughput (and, almost inevitably, reliability) than MH8A transmitters. Adding in other data fields or 2-way transmission with a rebreather would be...

You don’t have to hold the Suex trigger, FWIW. It would be nice if the speed control was on the handle though.

I can, but I’m in Canada (west coast) and I imagine the cost of shipping would be stupid.

I've printed a handful of things in nylon. If you're looking at pure PA6, you'll only need a metal hotend; an enclosure is also a really good idea for printing engineering plastics. If you're printing PA6-CF, you'd need hardened steel nozzle and extrusion gears to prevent wear. You also need a...

(Background: I have an XJ-S and Blacktips) One thing I've always wondered about the Genesis scooters: is there any kind of detent or marking that makes it straightforward to set at a defined 'cruise' speed? I use my (known, tested in different configs) scooter cruise speed as a big input for...

Adding an IMU is likely an immaterial electronics cost (like, $5). Adding position monitoring data was an area of benefit identified in RB4 (p227): "The forum identifies the use of accelerometers or inclinometers in rebreather heads as an opportunity for capturing body trim and movement data...

To add to this: the current list of light that you'll find handles for in that Onshape doc: - XTAR D26 1600S - DGX (DiveGearExpress) 1000-6 - Hollis LED1200 - Nanight X1 - Orcatorch ZD710 If anyone has any other lights they need the model adapting for, shoot me a message.

No, they're (subtly) different. I've bought lots of stuff from GiDiveStore before, and they have the right part number (RG912050). Also worth noting the recall notice on the ATX exhaust diaphragms.

Followup question: do you have a standardized protocol for taking underwater viz measurements using a Secchi disc? When I looked into it before, Secchi disc measurements are heavily dependent on the light source, and things like natural light vs artificial light, placement of the artificial...

I recently picked up the (excellent) @DiveGearExpress 6-degree light, for use as a primary on shorter dives. I made a version of my (mostly) 3D printed Goodman handle, only slightly modified from my XTAR D26 version. You can download the file for printing from Onshape here; at some point, I...

FWIW, one easy thing I’ve started doing is switching to an aluminum BP instead of steel, and then adding a couple extra pounds of tail weight. I like the ‘soft’ V-weight systems that let you put weight in a Velcro pouch, just because it gives a lot of flexibility. Also marginal gains, but I...

Narrator voice: it did, in fact, leak. @Dont_Hold_Your_Breath , that will 100% leak. My hands are tiny so I don’t have a lot of experience putting the larger glove sizes on, but with some wriggling you should be able to get those creases out. The glove should also get smaller the further up it...

The other thing I realize, looking at the images: everyone is diving it with a necklaced 2nd stage, as well as the long hose. Don’t know if that perhaps means that they’ve nixed the fancy integrated-BOV double-hose reg option?
