What GPS unit?
~ Captain Paul's response to: ~ CBynum ~
I strongly suggest that you determine what maps the various units you are considering. Many individual go with a unit that has supplemental mapping that serves their needs. Check out the types of charts and mapping to see if they meet your requirements.
Most current units can deliver accuracy to within 9 meters when using the WAAS feature, so be sure that the unit you are considering has that capability.
Another feature is the weatherproofing of the unit. Standard is now an IPX 7 (water proof up to a submersion in 3 feet of water for one half hour.
In the weather we have in Louisiana it is almost a necessity.
The other consideration is the user friendly of the operating screens and if it can accept electronic downloads.
Generally the cost goes up considerably with the size of the screen and if it a touch screen.
Do your home work before making your purchase and you should many years of use out of the system.
