Shearwater has introduced two limited-edition versions of its Tern TX dive computer, available in blue and purple colourways inspired by healthy oceans and recovering coral reefs. Only 750 units of each colour will be produced worldwide, with a contribution from every sale supporting marine conservation organisations working on coral restoration and marine protection.

The Perdix 3 features a 2.2-inch AMOLED colour display protected by aluminosilicate glass. The housing is depth-rated to 260 metres and uses a user-replaceable AA battery, allowing divers to choose between alkaline, lithium or rechargeable NiMH cells.

The computer supports Air, Nitrox, Trimix, Closed Circuit/BO and Gauge modes, and can monitor up to four transmitters simultaneously. It includes an integrated digital compass and uses Shearwater’s Bühlmann ZHL-16C decompression model with Gradient Factors.

The device uses the Bühlmann ZH-L16+GF decompression algorithm and allows up to five adjustable gases. It features a 2in (51mm) IPS LCD monitor with adjustable, continuous illumination, a 170° viewing angle and 320x240 pixel resolution.

Designed with a streamlined, low-drag profile and universal fit, it moves naturally with you. The system supports Technical, Recreational, and Freediving modes and uses a dual-battery setup for redundancy and more than 20 hours of operation. It functions in temperatures from −10°C to +55°C and is depth-rated to 70m, or up to 120m in advanced setups. A full-colour optical display with adjustable brightness shows live dive metrics, ascent alerts, low-pressure and battery warnings, plus shared team updates. Paired Daïve Smart Gauges display each diver’s air pressure directly on the HUD.

The Suunto Nautic dive computer features a 3.26‑inch high‑contrast AMOLED colour display and is rated for deep diving scenarios, including sidemount, technical and hybrid configurations. It supports air, Nitrox and trimix, allows for up to eight gas mixes, and provides full decompression planning for demanding dives. Wireless tank pressure monitoring with dual transmitters is included, enabling real‑time data for sidemount or twin‑tank setups.

The Suunto Nautic S is a watch-style dive computer designed for recreational and technical divers seeking advanced instrumentation in a streamlined format. It features a high‑contrast AMOLED display, an elastic textile strap suited for wear over exposure suits, and a rugged build tested for demanding environments.

The Shearwater Swift GPS is a compact transmitter designed to extend the functionality of any Shearwater air‑integrated dive computer by capturing surface GPS coordinates of dive entry and exit points and providing real‑time gas‑pressure data during the dive. The device supports a depth rating of 200 metres and operates within an ambient temperature range of +4 °C to +34 °C (with short‑term tolerance from ‑10 °C to +50 °C). Weight is approximately 135 g and dimensions are 76 mm (length) × 34 mm (diameter).
