Figure 2 ASM1024-500 Housing, Rear View
The front optical glass port is also sealed with an O-ring, and is semi-permanently installed
(shown in Figures 3 and 4).
The main body of the housing is made of clear anodized aluminum alloy and is rated for
operations to a water depth of forty meters. The enclosure is designed for appropriately
displaced water volume, resulting in neutral to slightly positive buoyancy.
A pair of protective, black anodized skids are attached to the bottom of the housing. The skids
also double as locations for adding diving weights, to counteract any excess buoyancy of the
submerged enclosure with the instrument installed (shown in Figures 3 and 4).
Although all hardware used is top-quality stainless steel alloy, it is recommended that the
housing be rinsed off with fresh water after each diving session, prior to drying and opening.
Sacrificial zinc weights attached to the surface of the housing helps to safeguard against
corrosion (also shown in Figures 3 and 4).
