That's quickly why you should choose our M2
P E R FOR M A NC E . The super-simple battery system is a big plus with this computer. AAAs can be bought virtually anywhere, and a battery change can be done in seconds without tools, and without having to disassemble the computer. Compared to the other units in this review, the M2 has a small screen relative to its overall size. However, test divers found it very readable. Underwater, the primary screen is dominated by bottom time and nodecompression limits data. The M2 doesn’t use an NDL loading bar, but the white/yellow/red ascent rate graph is very intuitive. The alternate screen shows max depth and temp.
On the surface, a couple of button presses is required to show surface interval time. The M2 comes with a wrist strap long enough for both wetsuits and dry suits.
LIBERAL OR CONSER VATI VE. The M2 RGBM is one of the more conservative computers, even at its most liberal setting. It also offers the option of programming in additional safety margins.
O W N E R ’ S M A N U A L . The M2 RGBM’s owner’s manual comes in 12 (no kidding) languages.
There is good spec/technical info and the navigation illustrations in the back of the manual are helpful.
P C INTERFACE . The optional PC interface kit uses an infrared linkup called the IRIS.
B OT TO M L I N E . If your gear budget is tight, the M2 RGBM provides a lot of dive computer for not a lot of cash, earning our Best Buy recommendation.
