Mares BCD GUARDIAN ErgoTrim

Beschrijving

The ErgoTrim technology allows the diver to adjust buoyancy no matter the diving position.

The ERGO command can be used like a ‘classic’ inflator by an instructor when teaching, but will work as an air trim when in its dedicated holder.
The aircell is separated from the shoulders, meaning greater comfort in the shoulder area when inflated.
High lift aircell with winglets.
Monoplate backpack fits single or double tanks.
50mm swivel buckles.
Stainless steel D-rings.
Adjustable cummerbund.
High capacity cargo pockets with supratex stretch panels.
Smart trim weight positioning.
SLS weight system.
Visual confirmation of proper weight pouch insertion.
Personalizable label on weight pockets.

Color customization possible with a dedicated additional kit available to purchase in 4 different colors (code 417966).
An integrated slot allows the diver to add a line cutter with the optional color kit available to purchase separately.

In 2001, Mares took the dive industry by storm when it introduced AIRTRIM
technology. One of the most innovative BC features ever designed, it combined
inflation and deflation in one single, ergonomically well-placed control. While
inflation took place as usual, feeding intermediate pressure gas from the first stage
into the Aircell, deflation was carried out by pneumatically activating two exhaust
valves. These were placed at both ends of the BCD, one on the right shoulder and
one on the bottom left of the aircell, and they were activated simultaneously, so
that no matter the diver’s position in the water, gas was sure to be released. With
one valve high enough to vent gas, the other would be low enough to take in water,
so to prevent water entry into the aircell, both valves had a one-way flapper valve in
front of them. Oral inflation, if needed in case of an emergency, could be performed
via a medical-style tube housed in a side pocket. We called it AIRTRIM because it
made achieving the perfect trim so much easier.

That was in 2001. In 2022, Mares outdid itself by introducing version 2.0 of this
technology. We named it ERGOTRIM, because we combined pneumatic deflation with
the “standard” ERGO inflator. Well, not so standard. The BCD inflates and deflates
as with a normal inflator, but it has an additional button to feed the pneumatic
circuit. A rocker switch has been placed on top of the inflate and pneumatic deflate
buttons to prevent the user from operating both at the same time. If you are an
instructor and need to show standard maneuvers to your students, you can carry
the ERGOTRIM on your left shoulder. For everybody else, ERGOTRIM equipped
jackets have a sleeve in the back of the aircell which routes the corrugated hose
under the left shoulder and positions it in a holder. Ergonomically, it is similar to
the original, but it has a 40% higher flow-rate for inflation, is more integrated into
the BC and, in case of emergency, oral inflation can be performed by removing it
from the holder, bringing it to your mouth and exhaling into it. The end result is
a very streamlined BC, one-hand operation under all circumstances, a free left
shoulder and the peace of mind that comes with knowing that you don’t need to
change your position in the water to deflate your BC
