The Oceanic ProPlus 4.0 Dive Computer with Compass arrives as Open Box. May be missing original packaging and minor blemishes (not noticeable after 1-2 dives). This item does not carry a valid manufacturer warranty and includes no quick disconnect (QD) accessory. It features Bluetooth 4.0 for on-the-go adjustments before and after a dive, and a larger display area with 22% bigger digits for improved legibility during scuba sessions.

Designed for scuba and diving gear enthusiasts, the ProPlus 4.0 integrates an XL display with a wide font to enhance readability and includes an integrated compass for underwater navigation. It supports multiple modes of operation—AIR, NITROX, and GAUGE—along with automatic altitude adjustment to accommodate different dive environments while maintaining safe dive profiles.

Choose the right algorithm for your dive with Pelagic Z+ for recreational and deeper dives, or Pelagic DSAT for repetitive, multi-level diving. The dual-algorithm design lets you select the conservatism level to closely match your buddy's setup, facilitating synchronized diving without the need to cut a dive short.
