Micrologic Hand held Loran Voyager model. These units were made in the 80's-90's, it has a case, charging stand, service directory, and waypoint log book. There is no manual, the unit powers up, and is currently on the charger, other than that I am not sure how it works. I was told that some guys buy old loran numbers from charter guys, use the loran units to get out there, then mark the way points on their GPS. I am taking offers for this unit, cash or trade in gear.
