iON sensor placement:

2 Tapeswitch sensors in each button for better sensitivity

Like ITG dedicabs, DDR cabs have four sensors per arrow; however, if I remember correctly, DDR sensors are much smaller (taking up about half a panel equidistantly from the center, in comparison to ITG's much larger sensors, taking about 80-90% of the panel size). Because of this, on a DDR pad, you'll have to fine-tune technique to catch the up/down arrow sensors, whereas on an ITG pad, just barely touching it with the proper pressure will trigger it no problem.

However, the home versions of these pads (ITG to Blueshark as DDR to this) seem to give you less sensors, as well as different placement (a Blueshark has two sensors going horizontally across a panel, in comparison to an ITG dedicab having a sensor on each side of the square panel).
