Induro AT114 Test Resutls

The Induro 8M Alloy AT114 is a now discontinued aluminum model.  Its size and weight place it in the travel tripod category.  But its only real selling points are build quality and price.  It is constructed better than most cheap travel tripods but it pays for that in weight.  The stability is also rather poor due to the use of a very narrow bottom leg section.

The stiffness and damping data are the averages of 10 trials for each measurement.  The reported error is the standard error, except in the case of the damping data.  I have set the error in the damping at 10% as the standard error metric does not appropriately capture the error in fitting to the data.  All of the reported specifications are measured, with the exception of the weight rating.  The tripod is measured at full height, with the center column down.


Example data for oscillations about the vertical axis of the tripod:

Good fits, poor stability.

Example data for oscillations about the radial axis of the tripod:

Again, good fits, poor stability.
