Recently I have responded to several "sale" or "trade" adds on various forums and I have never heard back from the people. I have sold many detectors and accessories over the years and I ALWAYS take a few minutes to email the people who were not quick enough to purchase what I was selling. Also, the minute you sell an item or remove it from the classifieds, mark it as SOLD so more people don't try to contact you. A little courtesy goes a long way R.L.
