Yea I guess I was a little vague in what I exactly want to do.

I realize that civilian GPS is only good to within 3-20 ft., but I am hoping that the new 50 channel is a little better than that more like the 3' not the 20'. I want to be able to mark with the SI and then just jump up front on the troller and get into that 5-10' radius of structure and fish.

Just thought I would probe to see if it were worth 130 ofr another reciever to save some time in searching since in theory you could be off as much as 35-40 feet if you have the Antenna that far from your unit plus the error of the unit.
