Product Information

The SCUBAPRO Hydros Pro 2 Monorail Multi-Mount Accessory Plate Set is a two-plate mounting kit that attaches to the Monorail system of the Hydros Pro 2 BCD so you can carry knives, SMBs, lights, Hydros Ninja Pockets and related accessories above or below the Monorail and weight pocket. Each set covers one side of the BCD, and the plates can be installed on the left, right or both sides. It is compatible exclusively with the Hydros Pro 2 and will not fit the original Hydros Pro.

Who it is for

This set is for Hydros Pro 2 owners who want a personalized, streamlined gear layout: recreational divers who want a knife or light within easy reach, divers who carry an SMB, and anyone adding roll-out Hydros Ninja Pockets or bungee accessories. Because the plates sit behind the Monorail, the configuration stays low profile, which suits travel setups as well as everyday local diving.

Frequently Asked Questions

Does this fit the original SCUBAPRO Hydros Pro?

No. The Monorail Multi-Mount Accessory Plate Set is compatible exclusively with the Hydros Pro 2 BCD and is not compatible with the original Hydros Pro. It attaches to the Hydros Pro 2 Monorail system and is compatible exclusively with the Hydros Pro 2. If you are unsure which generation of Hydros you own, call or chat with us before ordering.

How many sets do I need for my BCD?

One set covers one side of the BCD. Each set includes 2 plastic plates and 2 stainless steel screws, so order one set if you want accessories on the left or right only, and two sets if you want plates on both sides. Mounting both sides lets you balance accessory placement across the harness.

What accessories can I mount on these plates?

SCUBAPRO lists knives, SMBs, lights and Hydros Ninja Pockets, and the plates also accept bungee accessories. The plates mount above or below the Monorail and weight pocket, so you can set the height that works for your reach. Attaching behind the Monorail keeps the result low profile and snag-free.

How are the plates installed?

The plates attach to the Hydros Pro 2 Monorail system with the two included stainless steel screws, a simple screw-in attachment that requires no modification to the BCD. The whole set weighs just 0.035 lb (15.8 g) and measures 4.53 in wide by 1.1 in high by 0.94 in long, so it adds almost nothing to a travel kit.

Review summary

4.8 122 ratings across the web

Reviewers consistently say the monorail fits the Hydros Pro 2 exactly and installs easily, adding attachment points beyond the D-rings for pockets, SMB, or a light.

What reviewers like

Fits the Hydros Pro 2 exactly as expected

Adds attachment points beyond the standard D-rings

Holds pockets, SMB, or a light securely

Easy to install and sturdy once on

Customers praised this essential monorail mount for the Hydros Pro 2, noting "build quality is much better than I thought" and easy installation. It provides crucial attachment points for accessories like SMBs, cameras, and knives. However, shoppers noted limited adjustability and asymmetric design requiring upside-down installation on one side.

Expandable BCD

A little tricky to attach to Hydros, but once on gives great attachment points for other items. I only wish it was more adjustable for different configurations.

Necessary for Hydros 2

They're kind of necessary for the hydros 2 if you want to attach accessories. The build quality is much better than I thought they'd be based on the pictures. The included screws are also much more secure than I thought as well.

need two

You need two one for either side.

Mandatory

Mandatory. Get two

Not that excited!

As much as I do like how these help with adding a pocket to the Hydros Pro 2 BCD, they only come made one way. For example, the way they are shown in the photo fits great for the right side of the BCD. However, if you want to use them on the left side, they have to be installed upside down, so if you wanted to have a pocket on both sides of your BCD, you can’t do it with these mounts. Scubapro should have made these mounts specifically for the left or right side.

A necessity for UW photography

ScubaPro Hydros Pro 2 Monorail (Hydros Pro2, Multi-Mount) is a must-have accessory for underwater photographers who want extra attachment points beyond the standard D-rings. I’ve mounted one rail on the left for my SMB, and the right side gives me a clean, stable spot for an action camera on the floatie handgrip.

The Hydros Pro 2 is an outstanding BCD—especially for anyone who has to travel for dive opportunities—but it’s noticeably light on storage and mounting options if you commonly dive with lots of add-ons. This monorail system helps bridge that gap and makes it much easier to carry and position the gear you actually want to use underwater.

Fits my Hydros Pro 2 perfectly. Easy to install, sturdy, and works exactly as expected. Great quality replacement part.

Multi mount Monorail

This is a fantastic product designed for the Hydro Pro2 BC, allowing you to carry both a knife and an SMB at the same time. It is extremely simple to attach and use.

Excellent wetsuit but will it crush quickly like other wetsuits?

I purchased a BARE 5mm Reactive wetsuit (open box), which was like new, to replace my 1.5 yr old BARE 5mm Velocity wetsuit which had collapsed to only 2.5mm after 3 diving trips (~100 dives). The Reactive wetsuit is well constructed and very flexible. I had to increase the size of the Reactive suit, as it was smaller than the BARE Velocity suit of the same size. Tremendous customer service by Dive Catalog to exchange the wetsuit for proper size. I hope the Reactive suit does not crush so quickly like my other wetsuits (BARE, Henderson, Pinnacle). Hoping that the new technology in this suit will keep me warm below the thermocline.

Perfectly Built

Best of the many many diver hangers in my life. Easily supports my steel-plated BCD, while still donned with all of my accessories. No cracks, bends, or dents. Has even supported my BCD w/ a steel 100 tank attached (not recommended, for safety purposes, though).

Will continue to use this hanger for the long-term. No brainer.

Go-to Dive Hanger

This is a must-have for every diver. It's the quintessential hanger for all dive gear in one small package.

DiveCatalog's "Quick Dry Multi Accessory Dive Gear Hanger for Boots, Gloves, Hood" is set at a great price for a great product. Versatile enough that I've purchased extra hangers to organize my BMX racing gear.

Must-have for divers and anyone looking to organize their adventurous outdoor activities equipment.

Solid Hanger w/ Tons of Options

Does it's job and then some. The added accessory arms gives you options for a multitude of storage solutions. Solid build, solid pricing, must have for owns of dive gear.

New to this hanger...Now I'm a believer

Used tons of dive hangers, but never an upside down hanger. Game-changer for me. Will now add more of these in the near-future.

With it's swivel head design, it can cram itself into my tight dive locker, while still donning a ton of gear.

DiveCatalog's "Upside Down Drysuit Hanger w/ Regulator and Accessory Hooks" is a great product with solid construction at an affordable price. All of that with Dive Catalog's customer support/satisfaction guarantee.
