The Model 5000 Altimeter offers a high contrast, backlighted liquid crystal display of altitudes from -1,000 to +19,990 feet in 10 foot steps.  It can also be set by the end user to display equivalent altitudes in meters with a 1 meter resolution.  It is intended primarily for ultralights and is powered from a 9V battery or external power up to 30VDC.  It is FAA certified for use in hot air balloons.
The Series 2000 Altimeter is a "top of the line" instrument and displays altitudes from -1,000 to +30,700 feet in 10 foot steps.  It has a custom backlighted liquid crystal display, calibrated barometric reference (Kollsman), audio-visual altitude alert function, vertical speed indicator and RS-232 type computer output.  It can optionally be supplied with a Mode C encoder and an OAT/density altitude feature.  The Kollsman scale can be supplied in inHg or mBar.
The Model J Tach/timer displays engine speeds to 19,990 RPM in 10 RPM steps.  The display flashes if RPM exceeds the user-set REDLINE value.  A flight timer and total engine timer (Hobbs) function is included.  A 9V alkaline cell powers it for years.  It can be configured to operate with almost any engine or rotating device.
The Electronic Flight Instrument (EFI) is our entry into the multi-function instrument field.  This unit simultaneously displays RPM, two exhaust gas temperatures, two cylinder head or one coolant temperature, altitude, vertical speed, flight timer, total engine timer (Hobbs) and a very versatile AUX(iliary) function.  Display contrast can be adjusted for viewing angle from the normal viewing position.  It is available in a rectangular format or a larger round package that includes two momentary magneto test switches.
