I got rid of my Bel RX65 for a V1, and I'm pretty sure it needs to get tuned up. I only get 3 or 4 led's of strength when I'm right in front of an automatic door opener.
Anyway, I bought it off of eBay for 270 bucks shipped (pretty good deal that I could not help myself from buying). Serial is intact and it is V1.8 with software version 3.813.
So... should I tell them I bought it from a friend or something or just say I want to get my detector tuned and act like I'm the original owner? Some have had luck with getting it done for free and others have had to pay 40 bucks so I wanted to know the trick of getting it done for free.
