The Design
The Pro 2000 HD follows its predecessors in having a user-adjustable hybrid bladder with a large expanding wing-style buoyancy cell at the back, but with traditional BC front sections that can be called into play when needed.
The new version is constructed using 1000-denier PU-coated Cordura for the outer bladder and 420-denier PU-coated Nylon for the inner bladder.
It also retains the integrated-weight system, zip pockets, seven stainless-steel D-rings and trim-weight pockets found on its predecessor, but adds an open-top back-up pocket on the right hip with a webbing lanyard and a small plastic D-ring to keep stowed items secure.
The Frame to Back Evolution System involves a new-style backplate to which the shoulder-straps are attached directly at the top via a horseshoe-shaped section with three adjustment options.
The straps are also anchored directly to the bottom of the backplate to give total stability.
A substantially padded cushion covers the backplate and is held firmly in place with Velcro.

Before I took the Pro 2000 HD for its first outing I spent time adjusting the harness position to improve its fit with my drysuit. Adjustment is very easy and carried out by removing two slot-head screws and moving the horseshoe section either up or down to relocate it via a choice of three holes with stainless grommets.
I found that the middle position provided the best fit for my body frame.

Under Water
I had loosened the compression straps either side of the bladder to ensure that the wing portion of the hybrid air-cell wasn’t restricted. This gave me an ideal orientation under water, with head slightly up, body almost horizontal.
While adopting this trim I was aware that air had migrated to the highest point, and had to swivel my body slightly and move to a position where I could
easily dump it for the ascent.
The three dump-valves (excluding the inflator hose) were positioned well, enabling me to get rid of any unwanted air in virtually any other orientation.
Inflation was quick and easy at the surface, but with the compression-straps loosened the bladder tended to push my face forward. I reached behind and pulled them tight, which had the effect of bringing the rest of the air-cell around my hips into play, and pulled my body upright. I had converted the bladder from a wing to a traditional-style BC almost instantly.
I had installed around 8kg of lead-block weights into the integrated pockets, which helped with the trim at the surface and also prevented the BC from riding up my body when I was vertical on the ascent.
The weight-pockets are quite small for such a substantial BC and I had to add weights to my independent pouch-belt to negate the extra lift that my drysuit gives.
The integrated weights felt very secure in use, and pulling them free was a single-handed operation. They were also very easy to replace.
D-ring placement seemed ideal. There were plenty from which to choose to provide optimal positioning of my gauge, octopus and ancillary stuff such as reel and DSMB.

This latest incarnation of the Pro 2000 HD from Seac is a worthy successor to the older model. Seac has kept all the best bits (and why not, if it ain’t broke?) and added a new backplate and harness system.
It’s comfortable, easy to adjust and to wear. However, it’s the bladder-system design that continues to set this BC apart from the also-rans. It’s not new or unique but it still works better than most of the other hybrid wing buoyancy compensators that I’ve tried.
One last gripe, however, is that the whole thing is a bit on the heavy side.
In this world of inadequate baggage allowances I would be reticent about travelling with it for this reason,  even though the build quality and top-notch materials used in its construction make amends.
