Counter-lungs for the MK6 from Poseidon

Price incl. shipping 150EUR

Complete argon set consisting of:

  • Pressure reducer Poseidon Cyclon 5000 (with built-in pressure relief valve)
  • Mini-Finimeter Poseidon (sauteuer ;-) )
  • Inflator hose 60cm (slightly shorter compared to the standard hoses), very good yield
  • Steel bottle 2l, kk valve, connection G5/8" air (T├ťV expired, always stored under pressure). Very clear signs of use. Shipping is pressure-free.
  • 2 straps for screwing to the backplate. I liked it much better than the attachment to the double pack, because the argon bottle then hangs nicely close to the body and does not lie on the wing.

Due to the high-quality controller I would like to have 150 EUR incl. shipping.

The sale takes place under exclusion of any liability for material defects.


Zyklon 300 with Inflatorschlach was used as a second machine. 95 EUR

Hello sell here a regulator from Poseidon.

The serial number is 902724

The system is with bag and instructions for use and was used once.

Langenfeld Rheinland

Clean up my office, real antiques, nothing plastic! 3 double hose machines, Dr├Ąger/Kaiman/Medi, 1 Dr├Ąger full face mask, 1 Poseidon Cyclon 300 metal. Condition great, all freshly maintained before they got to my office over 20 years ago. Are probably submersible, but much too bad for that. Like to sell in a package, prices VHS. I do not react to "was isse letzte Preis" and inquiries "Ey Alter, beg isch Dich 30 f├╝r den alten Automaten". These machines were already in use when most Tekkies didn't even pee in diapers for the first time.

This regulator is the favorite of many marine divers, fire divers, police divers and professional divers, because it is robust and provides reliable air in all situations. Its approval up to 200m diving depth makes this regulator also the first choice for all technical divers. The world's first pilot valve-controlled regulator impressively meets the high demands of professional divers. It can be used and popular from the cold water off Canada, as an ice-proof regulator, to the tropically warm Indo-Pacific. Like all Poseidon regulators, there are no differences between diving up and down and it can be breathed from the right or coming from the left. The laterally dissented bubble deerer ensures a good field of vision when diving.

  • Manufacturer Poseidon
  • The professional's machine for extreme dives up to 200m
  • Connection shaft with G5/8" 300 bar connection
  • 1st stage membrane controlled/compensated
  • 2.Stage pilot valve controlled
  • 5x medium pressure outlets UNF 3/8"
  • 2 high-pressure outlets UNF 7/16"
  • Safety valve for medium pressure in the first stage



The sale takes place due to complete conversion of the equipment. The controllers are in perfect condition and were last serviced in mid-2019 (protocols and invoices can be submitted) and also regularly dipped until 03-2020. It would simply be a pity if the regulators now acid sour on the shelf.

I have several 1st and 2nd stages of the Poseidon xStream series including inflator hoses and consoles around, so I'll list the individual components including price here:

Original price price

Poseidon xStream MK3 deep, 1st stage approx. 430,- 300,-

Poseidon xStream MK3 deep, 2nd stage about 270,- 190,-

Scubapro 3 series console approx. 160,- 110,-

Suunto CB-3-Inline console about 250,- 170,-

Sets (suggestions):

Poseidon Complete Set 1st/2nd step approx. 630,- 450,- (+ 15,- with 150 cm flex hose)

Poseidon Complete Set Octo 1./2x2. Step ca 900,- 600,- (+ 10,- with 150 cm flex hose)

If someone wants a whole set of cold water - i.e. 2 1st steps, then I am also happy to send an offer. Prices subject to availability, if it's gone, it's gone.

After the system changeover, separate me bit by bit from my no longer needed equipment.

I offer here a new second stage Poseidon Jetstream incl. medium pressure hose. Unfortunately, I ordered one too many of them and can no longer exchange them. So this is new material that I have to resell privately.

A very reliable machine: Completely suitable for cold water (according to EN250) - have you ever heard of an icy jet stream?! The complete lung automaton is 300-bar compatible and can be used together with a first stage.
