(Note - ‘Remove before Flight’ tag is not included with product. It is shown here to highlight the pyro safety shunt plug, which is included.). A Safety shunt with the “Remove Before Flight” banner can be ordered for $8.00

Here is the G-Wiz MC2 Recording Altimeter. Features include more programmability, A 4th pyro port, and External Shunt!  See the Specifications below.

MC2 Specifications:

• Pyro output 1 - Jumper select between Launch detect (for clusters) and Burnout detect (for staging).  When Staging, 1st, 2nd, or 3rd stage selectable.  Optional timer as well.
• Pyro output 2 - Fires at Apogee detect.  Apogee detection is generally based on Accelerometer data, but Barometric Apogee can be selected, and is not subject to problems with Mach transition.  Also with optional timer.
• Pyro output 3 - Fires at a programmable low altitude, settable in 10 (foot or meter) increments. Also, may be configured to fire a  given number of seconds after Apogee instead.  Also with optional timer.
• Pyro output 4 - User programmable. May be turned on with one event, and off with another. Or with an event plus a time delay in both cases.
• Status LED / Speaker shows and beeps readiness at launch, and maximum altitude plus optional maximum speed upon landing. Readiness consists of Continuity checks, and both CPU and Pyro battery voltage levels.
• Arming jack provided on board, and via terminal block for external placement.  Not vibration sensitive, and continuity checks work even when disarmed.
• Analog to Digital converter reads accelerometer and barometric sensors to 12 bit precision. Equivalent to about 7 ft/count barometric, or .03 G per count acceleration.
• Acceleration and Barometric data sampled and recorded 33 times per second along with all detected events.  Enough memory on board for up to 18 min of flight (128k), and can record multiple flights.  More memory available as an option.
• Barometric altitude to 70k+ feet
• Altitude selection, and readout in English (feet) or Metric (meters) units.
• USB or RS-232 connection.
• Graphing software provided works on PC/Windows, Mac
• Software updates provided free on web.
• High performance processor uses proprietary techniques to calculate altitude properly. It does not rely on linear simplifications, but follows atmospheric pressure to altitude models very closely.
• High current FET driven pyro outputs are capable of delivering up to 15 amps for a full second, each.  Outputs capable of delivering up to 50 amps are available on request.
• Can use 2 batteries to ensure that the battery driving the pyro output does not interfere with the computer.
• Optional low current mode (jumper selected) allows use of one battery by limiting current draw.  Works with DaveyFire 28B and Pratt Hobbies WEC-1A. May work with other low-current matches as well.
• Reverse voltage protection on all connections.
• Positive retention header is standard.
• Complete with mounting standoffs and battery clips.
• MC HiG has a 100g sensor, for those extreme machines!
• Unit dimensions: 4.9” x 0.9”
• Prices:  MC2: $194.95 SRP, MC2 HiG: $249.95 SRP
• Optional RS-232 Interface: $35 SRP
• Optional USB Interface: $35 SRP
• One of above needed for connection to PC
