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
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. Several owners note the Hydros Pro 2 is light on storage out of the box and this adds the mounting space back. Suited to Hydros Pro 2 owners adding pockets or accessory points.
