Here's the deal: I am willing to give this away. Instead of taking it to the dump.
Perhaps one of you has this unit and wants this as backup instead of the aggravation of swapping in a new one someday. Unlikely but perhaps.
But it is going to be expensive to ship and you would pay that plus $20 up front for my handling.
but you don't need those if you already have this unit. It was working when I took it out of the boat in 2006. (Can you tell the Admiral has her foot on my neck to clean out the garage!
