can someone tell me the difference between VT 4.1 and VT 4.0?

So the 4.0 still has Buddy Pressure Check functionality?

the 4.0 has it, but you need to be holding hands for it to work. Not reliable at all.

the 4.1 when i talked to sales about 6 months ago, the feature was supposed to be removed. I do not know if it has.

Thanks. I guess like so many things it works better on paper than in practical application.
