Clearly you can't get it shipped to India. I had somebody in US order it from here:
eBay Motors: Digital Inclinometer--Clinometer/Tilt Gauge/Clino Gauge (item 170188635416 end time Feb-23-08 13:24:57 PST)
Later my boss carried it over from US to me last week, along with the E3.
Regarding the accuracy I have one problem. Although the inclinometer is very accurate by itself, the platform/dash isn't. I attached the meter using vaccum suction cups while parked on a very level ground. As you see it shows 0-0 reading.
But when I am going down a slope, it shows 18-20 degrees, but while coming up the same slope it shows 4-5 degrees. Does this have something to do with how the suspension works? Does the suspension get compressed to different extent while going down versus going up?
I am really confused about this one.
