DSO Nano V3 - where is the x10 probe?

I just bought the DSO Nano V3 off Amazon in the US. It came with two sets of probes, one with small clip, the other with pegs to plug into board. Neither has a x10 option. How am I supposed to measure 120V? Interestingly, I do see there is a menu option to set ProbeAtt to x10.
Any suggestions? Where do I get a x10 probe compatible with V3 (has 3.5mm earphone jacks, not BNC).

This adapter would allow you to use a standard X10 oscilloscope probe with your DSO nano.
