M1 RGBM
The M1
RGBM is the most complete
and easy-to-use dive
computer on the market, both
for recreational and
technical diving. Thanks to
the brand new Mares-Wienke
RGBM Algorithm, the first to
introduce Deep Stops, it
noticeably improves dive
safety margins.
A sleek and distinctive look,
controlled by just two
patented mechanical buttons.
Powered by two 1.5 Volt AAA
batteries, available
everywhere.
