Difference Between Highline I & II Meters

[5.4 Shelby]

Anyone know the differences between the 1st and 2nd generation Highline PTGs.? I see the I uses 4AAA batteries and II uses 1. Otherwise they look like same features such as 40mil max and both read steel and alum. the II also has a flip display.

I believe the display on the II is larger.

I guess what I really want to know is there a performance difference. Esp w the II only needing 1 battery and the I needing 4.
