I have been reading all these posts on Quatros and Explorers and it seems some say the return to threshold is very slow on the Quatro as compared to the Explorer 11, XS models, or the Sovereign series. I would like to know from someone who might have had all 3 machines, as to what they would rate them as to the return speed. I have been using a Sovereign for years and am thinking of getting one of either of the newer 2 machines, but I like the return speed of the Sov. and doubt I would like a very slow return machine. I usually hunt beaches, and I don't like to hunt very slow.
