Hey guys, new to the site and i have been reading up on these two detectors. I see that they are similar in appearance, but is there really anything that would make you pick one over the other? Basically i have been reading that they are exactly the same, except for the 690 has a compass and battery meter, is that the only difference? I was thinking bout the 690, but wanted you guy's input as to which one is better and why? Thanks
