I think he used the shove equity tool which made him able to determine how profitable a certain raise call was depending on the vilains shoving range.
Pokerstove can calculate how much equity you have vs a certain range but propokertools will tell you how much bb you will win or loose depending on the situation. It does not have ranges for HU. Its simply a more easy tool in my opinion to calculate the correct ranges for raise calling vs different vilains.
 

I actually wouldnt say it has the best ranges (preprogrammed) but ProPokertools is rather powerful. You can basically set your own handrankings if i´m not mistaken. And aside from that you can do a lot of other very helpful stuff to analyse certain situations.
