Thanks to everyone who helped me yesterday.
Last week I emailed Escort to find out how old my 8500 was. They told me it was 6-7 years old (revision 13). I decided then to upgrade and the first place I looked was craigslist. Came across a few and one in general stuck with me and tonight it was mine. Almost bought a blue one on eBay but held off thanks to the guys here. Glad I did!
Seller was a cool guy. Bought it a month ago from Best Buy. Said the cups broke right away and he didn't use it for awhile and needed the money.
When I plugged it in I noticed it sounded different than my 8500 and assumed they changed it but when I reset it to get the revision number (6.3) it sounded like the 8500 and that is how I like it!
Here are some pictures of it compared to my 8500.
Right away I noticed the 8500 seemed heaiver than the X50 so I ran downstairs and grabbed my dads old triple-beam and weighed them both..
X50 weighed in at 234 grams
8500 came in at 255.5 grams.
Notice it is not directly on the '--0' mark but close enough! I have the fans going so it was catching some air from that and the vents.
The X50 also seems a little bit longer too....
No cops out tonight. Actually saw five patrol cars but all were running with radar off or not on at all. Booooo. I am trying to find a spot where I can test them both at the same time and make a video of it. Stay tuned!
