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.
