Just my opinion, the AQ will stomp the D2 and specially the Nox, It will "test perfect" but get it in the wild.. it's another story, best to use it as a PI.  And don't get me wrong. The right person, with the right spot can do well using the disc side of the AQ. I love my AQ's but there are places I will not take the AQ and would much rather have the excalibur, or the D2.. And interesting there is no recovery speed on the AQ.. it can see gold thru pieces of iron the size of a golf ball
