Does the Pro Plus 4.0 Scuba Diving Computer include an attached compass?

You need to ensure your wrist has enough clearance for the 12 x 5 x 3 inch dimensions before you mount the device for a dive.

You can find our final verdict on the Oceanic Pro Plus 4.0 review to see if it meets your needs.

Pro Plus 4.0 features an integrated physical compass in the housing

The Pro Plus 4.0 features a physical compass integrated into the housing rather than a digital heading shown on the screen. This design means the compass is a permanent part of the hardware, so you do not need to carry a separate piece of equipment or worry about a mounting bracket. Because scuba diving computers often require clear visibility of life-support data, having a dedicated physical compass ensures the large display area remains available for depth and time. We selected the Pro Plus 4.0 for our comparison because it offers integrated navigation features among the dive computer options we evaluated.

• Verify that the 12 x 5 x 3 inch physical dimensions of the unit fit your preferred wrist size or mounting setup.
• Confirm that the “attached compass” includes the housing and needle in the box as a standard bundle.
• Check that the large font size on the display provides enough room for your specific gas mix requirements alongside the navigation data.
• Ensure the 1 CR2 battery requirement meets your planned dive duration needs.

Choosing the Right Dive Computer for Your Needs

The Oceanic Pro Plus 4.0 serves as a multi-gas dive computer, which is a wearable waterproof dashboard that tracks your depth and breathing gas. This specific model is ideal for experienced divers who require adjustable dual Nitrox mixes and a dedicated navigation tool in a single unit. If you prefer a minimalist setup without a physical compass or need a device with a different form factor, you should look for alternatives that offer digital-only navigation or different housing materials. For those who prioritize integrated hardware and a large display for complex gas calculations, the Pro Plus 4.0 remains a strong choice.
