Harry, guess it would depend on what was included with the 4500, keeping in mind, if I sold mine, it would include $1500 worth of evo coils, upgraded headphones,extra battery etc....mines not for sale though!
Depends on warranty. Had a guy on the weekend bought a 5000 including loads of coils and speakers etc.
But coils were broken and detector was very old and no warranty.
2 people offering detectors both have 1 post.
Seems legit :N:
New 4500's are a good buy if your looking at the 3.4k range
Sure there are plenty of decent second hand units too, just check any with minelab and give them a test / ask there history
