What is it?

Dedicated GPS units have been around for a long time already. Its original iteration was too bulky or too large to be useful for anything smaller than an airplane or a ship. Miniaturization of technology has allowed them to be portable.

How they work is to connect to a minimum of four satellites to triangulate your position and impose it on a map. This setup makes it extremely accurate because the satellites are unaffected by weather or even line of sight.

Do you need it?

Many people would simply say that a smartphone GPS is enough. It’s sufficient for day-to-day travels within where you live. If, however, you find yourself needing guidance for long-distance travel or even overseas trips or business, then a dedicated unit is a better option for you.
