Adrian Lim –
Used the AC-40 compass for my last dive at Pulau Tioman. The luminous dial is really bright—even during late afternoon dives, I could see the readings clearly. Strap was comfortable over my wetsuit, no slipping at all.

Does this compass work for navigation in the southern hemisphere or is it strictly for the north?
Imran Hanafiah –
Hi Mr Gan, the AC-40 North/Spec is specifically calibrated for accurate navigation in the northern hemisphere. For southern hemisphere dives, we recommend a compass designed for that region to ensure precise navigation.

The strap is easy to adjust, but I wonder if the housing will stay scratch-free after multiple trips. So far, it still looks new after a few shore dives in Malaysia.
Imran Hanafiah –
Thank you for your feedback, Ms Kumar. The AC-40’s housing is designed to be both shockproof and scratch-resistant for long-term durability, but we appreciate you sharing your observation and will continue to monitor customer experiences.
