Yes, thank you a lot PaulP!
We need more reviews from like PaulP's and the original poster to help substantiate all the postives and negatives of the XTR-695.
I find it discouraging to hear K-band performance couldn't even match an older cordless unit. I'm guessing Filter 1 and Filter 2 increase the threshold of signal strength at which the RD will begin alerting? I thought the Filter 1 and Filter 2 modes were only supposed to add a less than 0.5 sec delay to the initial alert in order to determine whether the source has the signature of a typical false alert or not. And why does this negative effect seem only to be prevalent on K-band and not Ka-band?
Plus, it's interesting to hear X-band does well considering the unit was not supposed to be too good at it (at least according to XTR-690 and PRO-78 users).
Good Citizen may be correct in the fact that the cordless may be effecting the XTR 695. I suspect this also and will test each unit independantly against a K Band speed sign recently installed on a nearby highway.
I have encountered an area in a city south of here where I get an almost constant KA alert on the XTR 695 ONLY. I covers an area of almost 4 square miles (even through a residential neighborhood). The signal runs a high 8 to 9 but no frequency is displayed indicating something other than a real threat (the freq readout has been accurate in only appearing under actual police radar). The 1788 gave no responce at all. I confirmed this noisy area the following day with the same results. Can only spot high tension wires at the south perimeter but no phone lines (all underground) or any other unusual source for the noise. Strange that the 1788 does not pick this up at all, especialy with such a strong signal. I turned off the cordless to see if it was influencing this but no change. Later in the day I had a similar account about 10 miles from there with a high and constant alert over a two mile drive in a warehouse district (turned on several cross roads to change direction). I drove away and returned with the same result. The 1788 did not respond at all as before. Any comments??
I finally got around to checking out this thread...
Welcome to the two new forum members, marko760 and PaulP! :D
I do so love reading user reviews of products -- especially when the reviews are more than just two or three sentences!
I belive the verdict is in. Today I tested the 1788 and the XTR 695 against a real stationary K Band radar gun. The 1788 has outstanding K band performance but would false 20 to 1 over the XTR 695 which I thought may be lacking in the K band range. My results show, after several repeat passes, that the 695 was as good or slightly better than the 1788 on alerting to the threat. The minimal falsing is in no doubt do to better filtering rather than a less sensative receiver. The 695's KA band performance has always been on the high side of excellent, and, with the exception of my previous posts on this, has given very few false alerts within the city. Much better than the 1788 and much better than my Bell. In my opinion, this detector cannot be beat at the under $200 price tag. I only wish that the display was a little brighter but is still better than most.
great stuff!
