Oceanic's MaxDepth is an air-filled analog instrument module with a time-tested design.
The MaxDepth has two needles; the one tipped in fluorescent pink marks the depth, the second, resettable needle records the maximum depth reached on each dive down to 200 feet. Depths from 10 to 40 have numbers for 10 foot increments and hash marks for 5 foot increments; those from 40 to 120 have numbers for 20 foot increments and hash marks for 10.
Since the shallow depths - 10 to 30 feet - are where critical safety/decompression stops take place, the scale for those depths has been expanded to make it easier to read. The depths beyond those considered safe for sport divers - 130 to 200 feet - are fluorescent pink,noting caution.
The MaxDepth has a luminescent face, making it easy to read in low light conditions.
The MaxDepth is an excellent instrument for novice divers. It can be popped out of a console easily and replaced with anOceanic dive computer whenever its owner is ready for the upgrade.
