Mike... I am sure you will like it , they are fun things.
All GPS units will give you the location , direction of travel , the way back (if you set them for that , most do it automatically ) the altitude , speed , the compass , way points for your favorite spots , distance traveled and distance to get where you are going , the travel time , the speed/direction at the present time and the speed it took to get where you are , along with more information then anyone needs.
The one in the Jeep ( just to name a few) will even let me know where restaurants , banks , ATM's , gas stations , campground , motels , Jeep dealers , gas stations , Hospitals , police stations , fire stations , state parks and National campgrounds and a ton of more information.
You dial in which one you want and from your present location it will take you there , step by step , turn by turn. It has over one million places of interest in it's memory , not counting up to date maps of the States along with Canada and I can add a lot more if I want to.
The one I have for traveling in the Jeep (the base of the unit is preferment mounted the GPS unit is removable for use out of or in the vehicle ) The wife has a removable (plug in or battery powered) one for the her truck and I have another hand held ( waterproof) for me when out paddling and camping. It is the 1st one that I had and still have.
They are nice but what really counts is the person using them and as that one saying goes ... "Never put all your eggs in one basket" .
They are a big help but it is the smarts of the person using them that counts and today they can get you right on top of what you are looking for , or within a few feet of it.
Chuck.
PS. I still take maps with me.
