Hello everyone. I am hoping to get some advice. I have a 20 acre block of land. I am planning on putting a few marker pegs along a boundary line but my two corners are about 500m apart. i do have a survey map. i have purchased a Garmin Oregon 600 and have been reading some forums about people who have done similar projects using something called "Expertgps". I have downloaded a trial version but but feel that I have jumped in at the deep end so to speak. Can anyone tell me if I'm on the right track or not. I do know that it would not be very accurate but does not have to be. If you can help please try and keep it simple as I am not really tech savy and at 67 years of age dont think I ever will be. Thanks for any help.
