The motion sensor gadget being able to mark enemies was a good buff, but after some extended use I can attest that it still pales in comparison to the utility of the zipline. As a new set of buffs, the sensor should be 50% smaller, and be placeable on walls and ceilings. As of right now the sensor is far too large and obvious, making it nearly useless when enemies just shoot it after seeing the big metal cylinder standing out like a sore thumb.
