I have spent countless hours researching GPS trying to find a clear cut answer to my problem so if anyone can help that would be amazing


I run a large-scale event on the beach every year and we would like to record exact GPS coordinates for certain "points of interest" at our event ( ie. the corners of an event or endpoint of a fencing run. ) This would save us 2 days of remeasuring each year to locate these points of interest to begin event construction.

From what I have found all mobile devices are not accurate enough

and what I need is a GPS plotter that is WAAS enabled with a high sensitivity chipset installed.

I need to be accurate up to 3 feet but I would prefer to be accurate to 1 foot.

Is there anything else I should be looking for in a Plotter?

Any suggestions on a certain GPS plotter that would work?
