I LOVE the HB sensor.

I never use it though.
I use Ninja Pro.

Ninja pro owns anyone who uses the HB sensor. Mainly because most people who use it are so focused on it. As you said, it's kind of like a UAV. When I have Cold-Blooded on and the enemy have a UAV, sometimes people walk right by me.

Anyways, I used the HB a few times, but I had Bling (for silencer), Cold Blooded and Ninja Pro on. I don't like it though. I'd rather keep my marathon, cold blooded/stopping power, ninja pro class, where I can simply own most people who use HB sensors.

Or I stay far and snipe.
