10 Best Underwater Compass For Scuba Diving 2025 in the United States

The Aqualung Computer I550C with Compass is a dive computer that combines a digital compass with advanced dive modes, including Air, Nitrox, and Gauge, making it versatile for different diving styles. Its metal build offers solid durability, and weighing 1.43 pounds, it’s a bit heavier than simple compasses but reasonable for a device with multiple functions. The compass is integrated into a large, easy-to-read screen that includes backlighting, which helps with visibility in low-light underwater conditions.

The device stands out with features like wireless Bluetooth connectivity to manage dive data on your phone and a user-changeable battery that keeps your settings intact, which is convenient for regular divers. However, because it’s primarily a digital dive computer with a compass function, it may be bulkier and more complex to use for someone just needing a straightforward underwater compass. Its size and weight might feel heavy for casual users who prefer lightweight gear.

This product suits divers who want a reliable, multifunctional dive computer with compass capabilities, especially those interested in tracking dive data and managing gas efficiently, but it may be overkill if you only want a simple, compact underwater compass.

The Mares Mission Puck 3 Scuba Diving Computer Console is a versatile tool that combines a compact pressure gauge, a dive computer, and an integrated analog compass. This makes it a comprehensive option for divers who want to manage multiple needs with a single device. The strength of this product lies in its ergonomic design, which is both comfortable and durable due to its chrome-plated brass body.

The high-contrast screen with large characters and a 170-degree viewing angle ensures superior visibility even in low-light conditions, which is further supported by an effective backlight for night dives. The intuitive single-button operation makes it easy to switch between dive modes, enhancing user experience and safety underwater. The integrated analog compass provides precise navigation, which is crucial for underwater orientation.

The multiple lanyard attachment points add to its convenience by allowing secure placement during dives. However, the product's weight and size (12 x 6 x 8 inches and 1 kilogram) might be a bit bulky for some divers. This makes it best suited for recreational divers who prioritize reliability and ease of use.

The Scubapro 3 Gauge In-Line Console is a solid choice for scuba divers needing a clear and durable underwater compass combined with essential gauges. It includes a reliable oil-filled compass with a rotating bezel marked in 30-degree increments and offers up to 26 degrees of tilt tolerance, which helps maintain accurate direction readings even if the console isn’t held perfectly level. Luminescence on the dial is strong on all gauges, making it easier to read in low-light or murky water conditions. Built with rugged plastic and polycarbonate, this console stands up well to rough underwater environments, so it should last through many dives.

It combines a pressure gauge, depth gauge, and compass into a compact and streamlined unit that is lighter and less bulky than having separate instruments, which adds to comfort and convenience during dives. The pressure gauge reads up to 6000 psi and the depth gauge up to 200 feet, with added temperature display, giving comprehensive dive data at a glance.

One downside is its size and weight—at 6.6 x 12.5 x 3.4 inches and 1.5 pounds, it may feel a bit bulky compared to some modern digital consoles, potentially affecting ease of handling for some users. Also, as an analog device, it requires manual reading and interpretation rather than automatic digital displays. This console suits divers who want reliable, straightforward analog instruments in one package, especially those who prioritize durability and clear visibility over compactness or digital features.
