Excuse my English. I really apreciate advices in choosing a GPS . Iam going to be involved in design of preliminar routes for high voltages transmission lines, so I need a Gps capable of provide me information about coordinates of points of posible towers setlement and mainly a one which I could drain out data to generate the altitude profile of the terrain alongside the route I have been walked. I need this profile to point those posible locations of towers and figure out lenght of spans and have a preliminar idea that Im going to get enough clearance above ground from soil level to electric transmision lines.
Im thinking about a middle range price.
Best regards, for all of you. Thanks
