The Scubapro MK25 EVO A700 Carbon BT has a casing that is full metal to take advantage of the extremely high heat exchange rate. This makes this second stage such a great choice for cold-water diving. The front cover is hand-made out of carbon fibre, the same material you find on aircraft, and high-speed race cars.
 
Carbon fibre is extremely lightweight and, unlike metal that can change shape when dropped or struck against a hard object, carbon fibre can resist substantial shocks without damage.
 
The Scubapro A700 Carbon BT retains the same muscular performance as the all-metal A700. Its air-balanced valve technology and oversized exhaust valve work in conjunction with a well-designed sectional exhaust tee, a first-rate purge and responsive user controls to create a tech-tough breather with effortless inhalation and ease of exhalation that is unmatched. It's now just lighter and tougher.
 
Finishing off this premium air delivery system is a DLC (Diamond-Like Carbon) BLACK TECH coating that's applied to both the first and second stages. This unique coating not only lends a sleek technical look to the system, its scratch- and corrosion-resistant properties perform an important function in protecting the reg against the strains and stresses of technical diving as well as the ravages of the saltwater environment.
