So obiously a new guy here, I discovered the site after deciding to replace my 4+ year old Cobra 9600 that I really have thought has served me well (no tickets since buying it, ~2/year prior), however after a lot of reading on the site over the last couple weeks I've realized how false a sense of security I've probably had. Anyway, I've come into the light, and about to make a purchase, and have pretty much decided on the RX65.
I can get the Refurb Red 65 on Ebay from Escort with the S7 horn or the Blue brand new from another site (I'm assuming wih the M4 horn) for the exact same price (last day of offer I believe is today).
I've been reading all I can find about S7 vs M4 and know there's a lot of controversy, but there's one thig that I'm confused about. I've seen a lot about the range and off axis differences, which has many folks singing the S7's praises, however given the controversy and my NOOBness with relative happiness with a Cobra, I'm sure the M4 will suite me just fine as far as those issues go. Plus, superficially, I would prefer the blue for asthetic reasons.
The one thing I haven't been able to figure out is if the response time to IO/QT is different between the horns, or is it a difference between the RX65 and the X50? I can stomach a difference in time of notification of a second or two from range differences, but I really can't stomach the thought of the RD never even making a peep if the LEO is just quick enough on the trigger. If I'm recalling correctly (have done a lot of reading and may be misremembering due to info overload) the testing and videos comparing the response times were between an S7 Rx65 and an M4 X50. Not sure if the improvement in response time when enabling the RX65's USA mode was related to it's S7 horn or the differece in RD's themselves.
So basically what I'm wondering is, can I buy my eye pleasing Blue RX65 and still get the response time benefit of USA mode, because if not, I'll get the Refurb red, because at least for me, in that consideration, form definitely follows function. Thanks in advance!
