The Best Sidemount Regulators Set

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 set available.

For the average novice sidemount diver, there are some distinct advantages to buying a complete sidemount regulators set rather than attempting to source and obtain individual components. You do, however, need to look closely at what’s included with these sidemount regulators 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!).

Article Contents

The components of a typical sidemount regulators 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 in length
  • A short hose of 24-28cm in 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 hoses) rather than donating a long hose. The DiveRite system listed below gives an option for that.

DEEP 6 Signature Sidemount Regulators 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 Deep6 sidemount regulator review.

The Deep6 Signature sidemount regulators 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″)

  • 1x Regulator protective dry box

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 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 regulators 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

The Apeks XTX sidemount regulators set 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
  • Cold Water Rated: Yes
  • 2nd Stage Convertible LH/RH:  Yes

Apeks MTR-X Sidemount Regulators 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 Apeks MTR-X review.

The Apeks MTR-X sidemount regulators 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

Apeks MTR-X sidemount regulators set specifications

  • 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
  • Swivel: Yes
  • Cold Water Rated: Yes – extreme cold water rated
  • 2nd Stage Convertible LH/RH: Yes

ScubaPro Mk25/G260 Sidemount Regulators 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 has put together a set comprising the latest MK25 Evo first stages and lightweight G260 second stages (the successor to the G250).

Scubapro Mk25 is 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 regulators 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

Scubapro sidemount regulators set specifications:

  • Connection Type: DIN 300bar
  • 1st Stage Design: Balanced 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: Yes

DiveRite Sidemount Regulators

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 traveling divers using rental tanks – as most DIN tanks will have 300 bar valves on them.

Price: Not Listed on Website

The Agir-Brokk sidemount regulators 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

The Agir-Brokk sidemount regulators set 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
  • Swivel: Yes
  • Cold Water Rated: Yes
  • 2nd Stage Convertible LH/RH:  Dedicated LH/RH
  • Weight: 3160g

Atomics M1 Sidemount Regulators Set

Atomics M1 Sidemount Regulators

Atomics has a very high reputation for its 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 traveling in less developed regions.

Price: $1540.00 (DiveRightInScuba)

The Atomics M1 sidemount regulators set contains:

  • 2x M1 1st Stages
  • 2x M1 Second Stages
  • 1x  60″ or 84″ Long Hose (optional)

  • No. LP Ports: 5
  • 5th/Bottom Port: Yes
  • Swivel: Yes

  • 2nd Stage Convertible LH/RH: Dedicated LH/RH

DGX Custom Poseidon Sidemount Regulators Set

Poseidon Sidemount Regulators

Poseidon doesn’t offer a sidemount regulator package, but USA online dealer ‘Dive Gear Express’ has put together a complete set.  Poseidon regulators are renowned 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 regulators 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
  • 1x 22″ (56 cm) Short 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 sidemount regulator setup is probably far more complex, confusing, and expensive than you need it to be. However, you can always buy the regulators and hoses separately and make a good set-up.

The UTD sidemount regulators set contains:

  • 2x PZ-1 1st Stage Regulators
  • 2x BZ-2 2nd Stage Regulators

UTD sidemount regulators set 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

  • Cold Water Rated: Yes
  • 2nd Stage Convertible LH/RH:  Not Known

HOG D3 Sidemount Regulators Set

HOG is 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 regulators 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

HOG D3  sidemount regulators set 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

I will try and keep this list updated – so if you know of any new releases or changes to what I’ve written… please let me know.

Adding air integration (AI) to sidemount regulators

If you will be adding AI functionality to your sidemount regulator set, see my article on setting up AI transmitters for sidemount.

Similarly, if you need an air integrated computer with specialist sidemount mode capability to monitor both primary cylinders simultaneously, see my review of the Top-5 sidemount dive computers.

  1. Hi There,

    Completed my SDI sidemount course recently, and loved the sidemount configuration overall!

    I am seriously considering getting the Tecline R2 Sidemount set. I plan to do some cave diving, but living in a tropical country, won’t be doing cold water dives (I really don’t want to fuss around with a drysuit anytime soon).

    I can’t seem to find reviews on Tecline (most things sidemount are difficult to find reviews on). Would I be fine using Tecline R2 for cave dives?

  2. There is also a Set from Mares based on XR28. Have not dived it yet but it’s on my purchase list ahead of Apeks due to the exchangeable valve seat.
