This is the Great Planes GloBee Multi-Blade (2,3,4-blade)
Digital IntelliTach Tachometer.
Some Important Differences Added to the IntelliTach over the standard Tach are:
Improved optics and sensor
Digital microprocessor that safeguards accuracy and provides
several nice functions like:
It can be set to automatically read the type of prop you use most,
whether it is a 2-, 3- or 4-blade style
It "remembers" the last three readings, so you don't have to
It shuts itself OFF after 5 minutes to save power
LCD display flips up to a comfortable reading angle
FEATURES: 0 - 32,000 RPM operating range readout is highly visible in
large 1/2" (13mm), 5-digit LCD display.
Measures RPM for peak engine performance up to 12" (305mm) from the
propeller, and still gets readings accurate to the nearest 10 rpm.
One-button operation to select among 2-, 3-, and 4-bladed props
with prop selection indicator on left side of the display.
1 year limited warranty beginning at date of purchase
INCLUDES: One Digital IntelliTach Tachometer
One 9V alkaline battery
SPECS: Length: 4-7/8" (125mm)
Width: 2.76" (70mm) handheld end
Width: 3.25" (82.5mm) screen end
Thickness: 0.98" (25mm) handheld end
COMMENTS: Because of its sensitivity, the unit does not know whether it is
looking at a propeller or an incandescent or fluorescent light,
which typically strobes at 60 cycles per second or 3600 cycles
per minute. When set for 2-blades it will read 360 or 3600,
3-blades: 240 or 2400 and 4-blades: 180 or 1800. This is a quick
way to test the calibration.
In direct sunlight this will read zero when turned ON.
