I have an Aladin 2G console 3 IMP but I can not find instructions for it other than the cheat sheet. If there an instruction manual or an online tutorial to help me understand how to use it?
I am looking for a dive computer (fresh and salt water) that is (a) very intuitive, and (b) will download dive data onto a Macintosh computer
Not aware of any of the dive computers that are Mac compatible. For ease of setup and use look at the Atomic Cobalt http://www.scuba.com/scuba-gear-16/009307/Atomic-Cobalt-Air---Nitrox-Integrated-Dive-Computer-with-Digital-Compass.html
what is the best regulator for the easiest breathing?
Any of the regulators in the top of line section will be the highest performance. http://www.scuba.com/scuba-gear-36/Regulators-High-Performance-Over-400.html
ALADIN 2G is a clear example of relentless development at SCUBAPRO. Engineered for technical divers who want specific features for total freedom in full safety, and for recreational divers who appreciate detailed, yet easily accessible information, but want the possibility to evolve in the sport. The ALADIN 2G combines this sophisticated algorithm with the compact size and accessibility of the Aladin family.
PDIS (Profile Dependent Intermediate Stops) optimizes your dive by calculating an intermediate stop based on how much nitrogen uptake your body has endured, taking into account your current dive, previous dives and breathing mixes. PDIS is a unique scientific application for safer technical and recreational diving.
Apnea mode with unique features specific to the science of Freediving, and separate logbook.
Gauge mode: operates as technical depth gauge to a depth of 394ft, with one-press stopwatch function. Unique in the diving industry, in this mode it displays a continuously updated average depth, which can be reset by the diver at any time.
Bookmark function during dive: highlight specific moments with a simple button press and add comments in the SmartTRAK profile later.
Altimeter: accurately measures altitude with a 50ft resolution. The altitude alarm (patent pending) alerts the diver when approaching an altitude incompatible with saturation status due to a recent dive.
Active backlight with push-on, push-off function.
Algorithm: ZH-l8 ADT MB PMG
PDIS: Profile Dependent Intermediate Stops
Microbubble Suppression Technology: six levels (0-5)
2 Nitrox Mix capability: program any two nitrox mixes to calculated decompression accounting for the switch to a richer mix at the end of the dive
Nitrox compatibility 21 - 100%
Bookmark Function during Dive
Gauge Mode to 120m/400 ft
Customize Audible Warnings
Safety Stop Timer (duration can be set between 1 and 5 minutes).
Adjustable backlight duration (2 - 12 seconds)
100 Hours of Profile Storage at 4-second Sampling Rate
