Mini Compass CMP/CMP2 - Compact IPX5 Waterproof Navigation Pendant

In this review of the MecArmy CMP/CMP2 mini compass the bottom line is simple: this is a small, well-made navigation pendant for hikers and everyday carry users who want a stylish, weatherproof backup compass. The compass stands out most for its compact, attractive metal housing and its IPX5 resistance to splashes and rain, making it useful on trails or attached to a bag. It is best as a decorative, practical accessory rather than a primary precision navigation instrument.

Key Features

• Compact & Weatherproof: The IPX5 rating and ultra-portable size mean this compass can be used in wet conditions and easily clipped to a keychain or pendant cord without adding bulk.
• Luminous Dial: The glow-in-the-dark face provides nighttime visibility so users can read direction after dark without an external light source.
• Durable Materials: The metal construction in brass, copper, or titanium gives a solid, well-machined feel and resists everyday wear when carried on a backpack or keys.
• Wearable Design: Its compact form doubles as a pendant or charm, making it an attractive accessory for graduates, travelers, and outdoor enthusiasts.
• Practical Attachment: The piece easily attaches to chains, cords, or keyrings so it stays accessible during hikes, commutes, or travel.

Who It's For

The CMP/CMP2 is aimed at hikers, campers, scouts, travelers, and people who appreciate a small, stylish piece of gear that also serves a basic navigational purpose. It works well as a meaningful gift for graduations, birthdays, or baptisms for recipients who enjoy the outdoors or EDC accessories.

It is not intended as a precision survey or professional navigation tool; users who need highly accurate bearings or a larger, more stable compass for advanced navigation should look to larger, dedicated instruments with sighting features and compass housings designed for high accuracy.

Pros & Cons

Pros

• Attractive, well-machined metal build that feels premium and holds up to daily carry.

• Glow-in-the-dark dial is genuinely useful for low-light orientation as a backup aid.
• Compact size and pendant/keychain design make it versatile and wearable.

Cons

• Some users report mixed accuracy and occasional needle wobble, so it is best used as a backup rather than a primary navigation device.
• The small size may feel too tiny for those who prefer a larger dial or clearer markings.
