Hello Senior Deacon.....

I bought my 5900 Di Pro SL (cb) late into the game about 2008 but mine was new in the box condition. According to the sticker in the battery compartment, my unit was made in 1994 and I paid too much for a 14 year old metal detector. I just adore this detector because it looks new and works extremely well. I run quite a bit of Signal Balance and a slight positive Ground Balance. With the 5900 CB set this way and using a 6 1/2 inch coil...it may be used with a slower sweep speed and does well in trashy areas.

Regards........Randy
