3D Concepts offers a compact SLR calculator with a clip so you can attach
it to your tripod while out shooting.  It has a scribed plexi-rule that
allows you to simply and quickly you cross reference any two unknowns
below, to figure out the third unknown.

1) Lens focal length (in mm up to 500mm)
2) Stereobase (in ft/in up to 100ft)
3) Distance (in ft) to closest object in viewfinder (from 3ft to 1 mile)

Parameters based on the equation  b=np/f
b=base
n=nearest object
p=parallax of 1.2mm
f= focal length @ infinity

For pricing information...go to Sell 3D, since P3D is for information only
