Shearwater NERD 2 Dive Computer + Swift Transmitter Package

This package pairs the Shearwater NERD 2 dive computer with a Shearwater Swift transmitter, giving you a heads-up air-integrated display plus the wireless sensor that feeds it tank pressure. The NERD 2 puts your dive data in your line of sight instead of on your wrist, using a micro LCD and magnifying lens so the numbers read clearly without breaking your view of the reef or your buddy. At checkout, pick the connector that matches your setup: Model SA, DiveCAN Monitor (5-Pin), DiveCAN Monitor (5-Pin) - JJ, DiveCAN Monitor (5-Pin) - O2ptima, Monitor AK (4-Pin), or Fischer.

The NERD 2 runs Air, Nitrox, 3 Gas Nitrox, OC Tec trimix, CC INT fixed PPO2, and Gauge modes on the Buhlmann Gradient Factors algorithm, with room for 5 open circuit and 5 closed circuit gases. It reads tank pressure from up to four transmitters at once, carries a 3-axis tilt-compensated compass, and mounts on most regulators via a universal 17-21 mm hose fitting, with extra hole patterns for custom or NERD 1 mounts. An internal rechargeable Li-ion battery gives you 18 hours of dive time per charge through the snap-on USB clip, and Bluetooth wireless technology keeps firmware updates and logs easy to manage.

The Swift transmitter is the piece that talks to the NERD 2 over the air. It threads onto a regulator first stage high-pressure port with no tools, runs on a user-replaceable CR2 battery good for up to 300 dive hours, and is built to work with any Shearwater air-integrated computer, not just this one. Its collision avoidance system keeps readings reliable even when several divers in the same group are each running their own transmitter, and an LED status light gives you a quick check before you gear up.

• Heads-up display Micro LCD (QVGA 320 x 240) with magnifying lens so data appears like a 25-inch TV at 12 feet, viewable without lifting your wrist.
• Air integration NERD 2 displays tank pressure from up to 4 transmitters in all modes, fed wirelessly by the included Swift transmitter.
• Dive modes Air, Nitrox, 3 Gas Nitrox, OC Tec (trimix), CC INT fixed PPO2, and Gauge, running Buhlmann Gradient Factors decompression computing.
• Depth rating NERD 2 rated to 300 m (985 ft), the deepest in the Shearwater lineup; Swift transmitter rated to 200 m.
• Universal mounting NERD 2 fits most regulators via a 17-21 mm hose mount, with extra hole patterns for custom and NERD 1 mounts.
• Tool-free transmitter install Swift threads onto a standard 7/16-inch-20 UNF high-pressure port by hand, no tools required.
• Collision avoidance Swift's advanced collision avoidance system keeps pressure readings reliable when multiple divers use multiple transmitters nearby.
• Long battery life NERD 2's internal Li-ion delivers 18 hours per charge; Swift's user-replaceable CR2 battery runs up to 300 dive hours.
• Connector choice Select from Model SA, DiveCAN Monitor (5-Pin and JJ/O2ptima variants), Monitor AK (4-Pin), or Fischer to match your existing gear.
• Matched wireless pair Both units are built by Shearwater specifically to work together, so pressure data reaches the heads-up display without a hose or gauge console.
