Hello,
I bought the Signum brand new in 2017. It has the 9.5 x 12.5" 7 khz coil. It is in excellent condition and works great. Easily my deepest detector even at lower sensitivity. 10" silver dime no problem in NY soil. The external speaker is slightly grainy sounding, but any headphones plugged in sounds perfect. I also removed the stock rubber grip, which I prefer, but grip tape can easily be added. Price is $425 shipped in CONUS. I accept paypal friends and family or paypal +3%. Thanks.
