Don't trust the accuracy - into a real aerial it's very dependent 
on the directivity of the coupler used. The VHF/UHF one is all but 
useless (25dB typ.) and they spout a load of nonsense in section 
3.2 'VSWR accuracy'.

If the VSWR reading changes with cable length, the sensor is not 
good enough.

I couldn't spot any directivity numbers for the hf ranges.

For all practical purposes it makes no difference that matters, 
but to me it's somewhere between sleight of hand and snake oil.
