The Shearwater NERD2 DiveCAN Monitor (5-Pin) JJ-CCR

is specifically designed as a DiveCAN Monitor (5-Pin) NERD 2 for the JJ-CCR.  It has an AK 5 pin connector.  Please make sure that you select the correct NERD for your system.    We also sell NERD's specifically designed for Optima, DiveCAN Monitor 5 pin, AK 4 pin Analog Monitor for CCR's and Standalone versions. The NERD2 is a full decompression dive computer incorporating the functionality of the Shearwater Research Perdix-AI, but with a display mounted on the diver's regulator second stage. This revolutionary device keeps crucial information in your line-of-sight for the entire dive. Thanks to the Micro LCD display and magnifying lens, the data appears as if displayed on a 25" TV screen, 12' away with no need to focus. If you can watch a TV without glasses, and even if you have a bifocal lens mask for reading gauges, you should have no problem seeing the NERD2. The display is unobtrusive as it virtually disappears when you look straight ahead. The numbers are there when you need them at any point during the dive, and out of the way when you don't. The full-color display is used to convey additional meaning with the information being displayed. When information is yellow or red, it calls the diver's attention to an unusual value or problem. During a decompression dive, the NERD2 provides complete information displays of all required stop times. The NERD2 can provide time-to-surface based on "look ahead" at planned gas switches. Multiple gas definition presets are supported with any combination of oxygen, nitrogen and helium. The NERD2 will NOT "lockout" after a missed stop or ascent rate violation. After the dive, the NERD2 communicates via next generation Bluetooth Smart Ready™ with iOS devices such as the iPad and iPhone. In addition to current Shearwater and third party support for Mac and PC desktop applications, users are able to download dives using their iOS devices in conjunction with third party applications. The NERD2 incorporates a built-in lithium-ion rechargeable battery. Users can expect a minimum of 18 dive hours, on medium brightness, from a fully charged NERD2 and 5 charges from the charge bank. The NERD2 is capable of wirelessly connecting to optional transmitters giving the diver ability to monitor up to four tank pressures. Air integration is optional for all modes, from OC Rec to CC/BO. The tank pressure(s), in PSI or BAR, can be displayed to the customizable slots on the main display screen or accessed through the underlying information screens. Enabling the AI feature causes approximately 10% decrease in battery life. Included with every NERD2 from Trident Warriors are a mounting clamp, recharging clip, charging bank, and USB cable. The software includes a complete dive log manager, compatible with both MS Windows and MAC OS X, and can be downloaded from Shearwater's website along with the manual. The dive log manager supports log downloads and firmware updates via the Bluetooth wireless interface. An optional PIN upgrade to the VPM or DCIEM decompression algorithms are also available.
