Operation:
The SkyCorder is simply turned on and set to zero ground level at the start of the day. It can be kept in a jump suit pocket or attached to a rig for automatic operation. No further attention is needed. At any time (except during freefall) the data for the last 25 jumps can be displayed in a logical format. With the computer interface, data can be downloaded directly into a computer logbook program.

Exit and Opening Altitudes:
The SkyCorder detects the acceleration at the beginning of freefall and saves the "Exit" altitude. When the skydiver slows down under an opening parachute, the SkyCorder records the "Open" altitude.

Peak and Average Rates:
The time in seconds between the exit and opening altitudes is also recorded and displayed as the Freefall time. The average rate is determined for each jump, including the entire skydive, except the sub-terminal time just after exit. The Peak (maximum) speed for each jump is calculated as the fastest speed maintained for any 5-second period during the jump.

Number of jumps:
The SkyCorder Stores all of its information for the last 25 jumps. After the 26st jump, the first jump will be lost. The jump number will count up to jump #99, even though only the last 25 will be displayed. The jump information will be saved even if the battery is removed. At any time, the jump data can be cleared. A special button sequence prevents accidentally clearing the data.

Freefall Time:
The freefall time for each jump is displayed in seconds. The total freefall time for all the jumps is displayed on the main menu in minutes and seconds (MM:SS). The total time is reset when the jumps are cleared. Although only the last 25 jumps are saved, the total time includes ALL jumps since you last reset. For example: after 32 jumps, data for jumps 8-32 can be viewed, but the total time is for all 32 jumps. 

Menu System:
All information and control is accessed through a simple menu system using two buttons and an LCD display. One buttons steps through each stored parameter for a selected jump. The other button steps through the recorded jumps, allowing you to compare a selected parameter for each jump. Control operations are protected by special button sequences.

LCD Display:
All of the information is displayed on an easy to read LCD display. With two rows of 16 alpha-numeric characters, the SkyCorder clearly describes the information in plain language. The display also provides prompts for control functions such as calibration and clearing data.

Ground reference adjustment:
The altitude can be adjusted to compensate for different field elevations and atmospheric pressures. The altitude can be set in 100-foot increments. The SkyCorder is usable from 0 to 18,000 feet above sea-level. Any ground elevation can be set to 0 for a ground reference. It can also be set to a negative number if you plan to land at a higher location. The altitude can be adjusted at any altitude (i.e. you could set it to match another altimeter while in the airplane).

Battery:
The SkyCorder uses a common AAA size battery (1.5 volt Alkaline). It has power saving modes which help the battery last longer. When no button is pressed in 30 seconds, the display turns off and the SkyCorder continues to record jumps. The display can be turned back on by pushing a button. The display will always turn off while in freefall. In recent tests, the battery in a new SkyCorder has lasted up to 300 hours!

Auto Shutoff:
The SkyCorder will automatically turn off 6 hours after your last jump (or 6 hours after it was turned on if there are no jumps). If you think it is almost 6 hours since your last jump, you can turn the unit off and on again to reset the timer so your jump won't be lost.

Engish or Metric units:
The SkyCorder can be ordered in English or Metric versions. The English version displays altitudes in feet (f), and speeds in miles per hour (mph). The Metric version displays altitudes in meters (m), and speeds in kilometers per hour (kph).

Computer Interface:
G R Devices has just released the new Computer Interface for the SkyCorder. A special cable allows you to connect your SkyCorder to your PC's parallel port (this cable allows your printer to also stay connected). Software provided includes the PC JumpLog logbook program from Impact Data. The data is also compatible with other programs through simple ASCII files. In addition, DETAILED DATA from the last jump can be analyzed using the software. Graphs show the altitude and speed at every point during the jump! These graphs can be saved in files or printed. The new SkyCorders are compatible with the interface, however older units may need software and hardware modifications. For more information click here.

Warranty:
The SkyCorder comes with a one-year limited warranty which covers defects in materials, workmanship and functionality.
