Ok I have decided that I wanted to go with a whilslter, since I have owen bel escorts unit. I wanted to try something differnent. But I just saw there E versrions of the pro 78 and 690. Does any one no when they are comming out, is the KA MAX features means its going to be more sensitiviy then the XTR-695. What should I do, should I buy an xtr-695 or go head and wait, see what this KA MAX means.
