I have an Explorist 500 for sale. It's in good condition, with minor scratches. It is running 2.70(8 screens) and receives WAAS. The unit comes with 2 rechargeable batteries, a AAA battery adapter, 1GB MicroSD card w/ adapter, all operations manuals and disk, a neoprene protective case, and I will throw in one more goody. I can send pics if requested. I am asking $110 + shipping. You can PM or email Kevin at kddavis1975@yahoo.com.
