Apeks DS4 alternatives for rebreathers

[Underwater Tourist]

Well, sucks to be me 50% then ;-( O2 is from '19.

At least you have some certainty, my SM regs were made exactly in June 2021

I play Apeks Roulette every dive

FX CCR config let’s you choose apexs or dive rite for fixed IP.

Why would the FX need a fixed IP?
Isn't it an eccr?

Triton mccr rebreather used to come with a modified DS4 (fixed IP). Now it comes with this specific regulator designed with Beuchat.

Btw the way, never had any problem with my DS4, got 4 of them with various second stages.

The JJ ships with Apeks US4 first stages.

I always swap mine out for Scubapro Mk11s - far better regulators with more easily available service kits.

The only Apeks regs I own (aside from the two brand-new ones taken of my latest JJ) are the ones I use to drive my booster. They're just cheap lumps of crappy brass that I wouldn't take underwater.

I should have added: I need a stage I can blank to avoid pressure compensation. Can you blank FT1s, @sea_ledford ?

Can you explain why on some rebreathers you should not have depth compensation?

Can you explain why on some rebreathers you should not have depth compensation?

Some manual rebreathers leak O2 into the loop with constant mass flow. If the IP rises with depth, more O2 would be pushed through the orfice. But you just want one 'surface liter' of mass going into the loop whatever the depth is.

Here's a reg I had Martin make, his man hadn't made one before, there's a photo of it on his page

What is an ADV on a rebreather? - Google Suche

get my ds4s from him too

25 years of old APEKS regs and still going strong forever

hCCR is an option, adds needle valve. I am assuming that makes it fixed IP.

, so would interesting to know if @rddvet had new regs that were made after June 2021 and still failed.

All of my Apeks are about 4.5-5 years old. The one that blew a week ago was serviced about 14 months ago

does anyone know where to buy a replacement main body for an apeks dst
