- Buyers looking for a vest attachment with a retractable reel, subject to confirming the selected configuration.

- Divers who need a compass explicitly calibrated for the Southern Hemisphere.
- Buyers who require a confirmed wrist-only or vest-only mounting setup without checking the listing configuration.

## Customer feedback

These figures indicate generally favourable ratings but do not reveal what customers liked or disliked, or how the compass performs underwater.

## Frequently asked questions

### Is the Mares Compas Pratique 414504 intended for Northern Hemisphere use?
Yes. The title and feature text describe it as calibrated for the Northern Hemisphere. The listing does not establish suitability for the Southern Hemisphere.
### Does it mount on a wrist or a diving vest?
The listing conflicts: the title and feature text describe vest attachment with a retractable reel, while the mounting details say Wrist Mount. Check which configuration is supplied with the selected listing.
### What is the oil bath for?
The listing says the compass is immersed in oil to provide a stable reading while moving underwater. This is a manufacturer claim, not an independently verified performance result.
