Less than 1 year old. Used on 10 dives, excellent condition, no scratches. Upgrading to an AOI-UWL-09 Pro
144 degree angle of view underwater.
Type 1 base has 2mm protruding rear element for gap between housing port glass and housing thread (Ikelite housings and some others). There is a conversion kit available from INON (not supplied here) to turn it into a Type 2 (flush rear element).
£500 (new price is £750)
PM me if interested.
Why? The Inon is 100% glass and the AOI has a polycarbonate front element?
Pro is also glass and has full zoom through but more expensive so have to fund it by selling existing first
Buy a Nauticam WWL-1 used then it makes more sense and that works for sure better on any rig
