A List of Sidemount Regulator Sets

by Andy Davis

A greater number of scuba equipment manufacturers are now offering dedicated sidemount regulator sets.  Here is my guide to some of the best sidemount regulators sets available.

For the average novice sidemount diver, there are some distinct advantages to buying a complete set-up rather than attempting to source and obtain individual components.  You do, however, need to look closely at what’s included with these set-ups and make sure that it’s appropriate for the BCD and configuration you will use.  If in doubt, consult your sidemount instructor (or drop me a line!).

The components of a typical sidemount regulator set include:

  • Two 1st Stage Regulators, ideally incorporating a swivel and 5th (end) IP port.
  • Two 2nd Stage Regulators
  • A long hose of 1.5 to 2m length
  • A short hose of 24-28cm length
  • An LPI hose (bottom routed LPI BCDs need an 8-12″, depending on chest size)
  • Two SPGs (small, flat SPGs are generally best)
  • Two 6-9″ SPG HP Hoses
  • A Bungee or Rubber Necklace
  • An angle adaptor for the short hose regulator (70-90 degrees)
  • A bolt-snap and attachment for the long hose regulator.
There are some approaches to sidemount that don’t use a ‘conventional’ long/short hose arrangement; preferring shorter hoses routed directly to the mouth from each side (ambidextrous 2nd stages).  This is normally for cave and solo sidemount diving, although at least one training agency is now advocating donating cylinders (with short hose) rather than donating a long hose. The DiveRite system listed below gives an option for that.

DEEP 6 Signature Sidemount Regulator Set

deep6 sidemount regulators

Price at only $880, the Deep 6 sidemount regulator package represents excellent value for money.  When ordering the set, you are given a lot of options in regards to hose lengths, SPG types etc…. making it a good option for sidemount, where one approach doesn’t fit everyone.  Read my detailed review HERE

The Deep6 Signature sidemount regulator set contains:

  • 2 x Balanced Diaphragm 1st Stages
  • 2 x Balanced 2nd Stages
  • 2 x High Visibility SPGs (1.5″, 2.0″, or 2.5″)
  • 2 x LP Regulator Hoses (20″ – 84″)
  • 2 x LP Inflator Hoses (9″ – 36″)
  • 2 x HP SPG hoses (6″ or 9″)

Apeks XTX50 Sidemount Regulators Set

Apeks Sidemount Regulators

Price: $1189.00 (£891 GBP)

The Apeks sidemount is probably the market leader in sidemount regulator sets, and deservedly so.  The set comes complete with everything you need for a slick set-up. It pairs very well with ‘Mexico Cave’ (British) style rigs…

Many of my students attend for courses with these regulators and, thus far, they’ve been immensely successful.  Apeks have a high reputation for quality and it is easy to get them serviced or repaired anywhere around the globe.

The XTX first stage is basically a DST with the optional swivel and end port.  If putting your own set together, you could also use the upgraded DST regulators.

The only thing I don’t like about the Apeks sidemount regulator set-up is that it uses nylon braided hoses.  These are generally less popular with technical divers and there have been some safety issues with them (read HERE).  If possible, ask your vendor if you can opt for rubber regulator hoses.

The Apeks XTX sidemount regulator set contains:

  • 2x XTX50 DIN Regulators
  • 1x 83″/210 long hose (nylon braided)
  • 1x 24″/60cm short hose (nylon braided)
  • 2x Brass SPG with 6″ rubber hoses
  • 2x 8″ LPI hoses
  • 1x 90 degree adaptor
  • 1x Bungee Necklace
  • 1x 75mm S/S Boltsnap (for long hose)
  • 1x Regulator Bag
  • 5 x Cable ties
  • 5 x O ring
  • 1 x 700mm Bungee Cord

Specifications:

Connection Type: DIN 300bar
1st Stage Design: Environmentally sealed, over-balanced diaphragm
1st Stage Material:  Chrome plated brass
No. HP Ports: 2
No. LP Ports: 5
5th/Bottom Port: Yes
Swivel: Yes

2nd Stage Convertible LH/RH:  Yes

Apeks MTR-X Sidemount Regulator Set

Apeks MTR-X Sidemount Regulators  

Price: £1360GBP ($1800USD)

The MTR-X is Apeks’ latest regulator design that is designed and optimized for very cold water reliability.  The 1st stages are turret designed with 5th/end-port; making them optimal for most sidemount hose configurations  I’m glad to see that Apeks is releasing this sidemount set with rubber hoses, rather than the braided hose that used to be included with their older XTX sidemount set.  Read more in my initial review HERE

The Apeks MTR-X sidemount regulator set contains:

  • 2x MTR-X DIN Regulators
  • 1x 83″/210 long hose (rubber)
  • 1x 24″/60cm short hose (rubber)
  • 2x Brass SPG with 6″ rubber hoses
  • 1x 8″ LPI hose
  • 1x 6″ LPI hose
  • 1x 90 degree adaptor
  • 1x 75mm S/S Boltsnap (for long hose)
  • 2 sets of diver interchangeable exhaust ‘T’
  • 5 x Cable ties
  • 1 x 700mm Bungee Cord

Connection Type: DIN 300bar
1st Stage Design: Environmentally sealed, over-balanced diaphragm
1st Stage Material:  Satin-chrome plated brass
No. HP Ports: 2
No. LP Ports: 5
5th/Bottom Port: Yes

2nd Stage Convertible LH/RH:  Yes

ScubaPro Mk25/G260 Sidemount Regulator Set

Scubapro Sidemount Regulators

 

Price: $1319.00 (£989 GBP)

I’ve dived with Scubapro Mk25/S600 regulators for over 12 years, both sidemount and backmount.  It’s surprising that Scubapro hasn’t copied Apeks and other manufacturers to release a dedicated sidemount set.  However, Simply Scuba in the UK have put together a set comprising the latest MK25 Evo first stages and lightweight G260 second stages (the successor to the G250).

Scubapro Mk25 are an awesome first stage, offering excellent performance for high-demand diving. They are also very well configured for sidemount use, with a swivel and 5th (End) port.    If you cannot find a sidemount set available, then this is one brand to consider putting your own set together with.

The Scubapro sidemount regulator set contains:

  • 2x Mk25 EVO DIN 1st Stage Regulators
  • 2x G260 2nd Stage Regulators
  • 2 x compact SPG
  • 2 x 20cm SPG hoses
  • 2 x  20cm LPI hoses
  • 2 x BPI quick coupling
  • 2 x DIN plug
  • 1 x 64cm Short Hose
  • 1 x 210cm Long Hose
  • 1 x 120° Angle Adapter
  • 1 x necklace

Specifications:

Connection Type: DIN 300bar

No. HP Ports: 2
No. LP Ports: 5
5th/Bottom Port: Yes
Swivel: Yes
Cold Water Rated: Yes
2nd Stage Convertible LH/RH:  Yes

Hollis DCX Sidemount Regulator Set

Hollis Sidemount Regulators

The Hollis sidemount regulators definitely scoop the budget award, coming in at less than half the cost of some other sidemount regulator sets on the market.  These are a good option for recreational sidemount divers, who might have a lot of kit to buy when first converting to sidemount diving.

Dive Gear Express, in the USA, offer an alternative set-up…. I’ve listed the details below.

DiveRite Nomad XT Sidemount Regulators Set

DiveRite Sidemount Regulators

The DiveRite XT Nomad sidemount regulators are designed for a sidemount configuration that doesn’t utilize an ‘around the neck’ (Hogartian) regulator hose approach.  Retailer Dive Gear Express does give options on hoses though – so you can specify more conventional hose lengths if desired.

The DiveRite Nomad XT sidemount regulator set contains:

Tecline R2-Tec Sidemount Regulators Set

Tecline Sidemount Regulators

Tecline is less well known in the USA, but has started to gain interest in Europe.  Their R2 Tec regulators are reminiscent of the Apeks XTX, but at a much cheaper price.  The version of 1st stage sold with the sidemount set is cold-water rated.

Agir-Brokk Sidemount Regulators Set

Agir-Brokk Sidemount Regulators

Agir-Brokk has a strong reputation for quality in the technical diving community, but their products are often difficult to source. These regulators don’t have a price listed on the Agir-Brokk website.  Perhaps that quality is so high that if you need to ask the price – then you probably cannot afford them?

For some reason, the regulators are only available in an uncommon 230 bar DIN fitting.  This means you can use them on 200 bar valves, but won’t be able to use 300 bar cylinders.  That’s a drawback for travelling divers using rental tanks – as most DIN tanks will have 300 bar valves on them.

Price: Not Listed on Website

The Agir-Brokk sidemount regulator set contains:

  • 2x  V10 1st Stages
  • 2x  2nd Stages
  • 2 x “Deco” SPGs
  • 2x  6″ HP hoses
  • 1x 83″/210cm Long Hose
  • 1x 29″ 74cm Short Hose
  • 2x 8″/20cm LPI Hose
  • 1x Bolt-snap

Specifications:

Connection Type: DIN 230bar
1st Stage Design: Balanced membrane, environmentally sealed
1st Stage Material:  Not listed
No. HP Ports: 2
No. LP Ports: 5
5th/Bottom Port: Yes

2nd Stage Convertible LH/RH:  Yes, dedicated LH/RH
Weight: 3160g

Atomics M1 Sidemount Regulators Set

Atomics M1 Sidemount Regulators

Atomics have a very high reputation for their regulators, and this reflects in the price.  The performance often rates at the top-end in comparative regulator tests.   With proven performance, the only real drawback is that some divers might find it harder to find a center for service/repair when travelling in less developed regions.

Price: $1540.00 (DiveRightInScuba)

The Atomics M1 sidemount regulator set contains:

  • 2x M1 1st Stages
  • 2x M1 Second Stages

DGX Custom Poseidon Sidemount Regulators Set

Poseidon Sidemount Regulators

Poseidon don’t offer a sidemount regulator package, but USA online dealer ‘Dive Gear Express’ have put together a complete set.  Poseidon regulators are renown for their ample gas delivery and reliable performance in cold water conditions.  The one drawback to this set is that the 1st stages don’t feature a swivel or 5th (end) port.  This can cause hose-routing problems with some sidemount configurations.

Price: $1099.00

The DGX Poseidon sidemount regulator set contains:

  • 2x Xstream Black 1st Stages
  • 2x Jetstream Mk3 Series 2nd Stages
  • 1x  60″ (1.5 m)  or 84″ (2.1 m)  Long Hose

UTD Sidemount Regulators Set

UTD Sidemount Regulators

UTD are popular as sidemount regulators, but they sell them as part of their unique ‘Z-System’ which makes use of an isolated manifold and QR6 disconnects.  If you aren’t a UTD trained sidemount diver, then that set-up is probably far more complex, confusing and expensive that you need it to be.   However, you can always buy the regulators and hoses separately and make a good set-up.

The UTD sidemount regulator set contains:

  • 2x PZ-1 1st Stage Regulators
  • 2x BZ-2 2nd Stage Regulators
(Not sold as a complete package – hoses available separately)

Specifications:

Connection Type: DIN 300bar
1st Stage Design: Air balanced flow-through piston
1st Stage Material:  Chrome plated brass
No. HP Ports: 2
No. LP Ports: 5
5th/Bottom Port: Yes
Swivel: Yes
Cold Water Rated: Yes
2nd Stage Convertible LH/RH:  Not Known

HOG D3 Sidemount Regulators Set

 hog d3 sidemount regulators

HOG are a very popular economical tech scuba brand in the USA.  The D3/Zenith set is an upgrade of the older D1/Classic sidemount regulator set.  I’ve had a few students on training courses who had the older HOG regulator sets – there were a few quality control issues raised.  I personally didn’t like the HOG mouthpiece… I think it’s too soft and flexible (but that’s easily changed).

Price: $635.00 (Dive Right In Scuba)

The HOG D3  sidemount regulator set contains:

  • 2x  Hog D3 1st Stage Regulators
  • 2x Hog Zenith 2nd Stage Regulators
  • 2x SPG’s
  • 2x  6″HP SPG Hoses
  • 1x 84″ Long Hose (60″ or 7′ option at Cave Adventures)
  • 1x 32″ Short Hose
  • 2x 90 degree adapters
  • 2x DIN Caps

Specifications:

Connection Type: DIN 300b
1st Stage Design: Balanced diaphragm
1st Stage Material:  Trivalent-Chrome and Black Zinc Chromate Plated Brass
No. HP Ports: 2
No. LP Ports: 5
5th/Bottom Port: Yes
Swivel: Yes
Cold Water Rated: Upgrade option
2nd Stage Convertible LH/RH:  Yes
