rand dist-o-map or clear plastic ruler on Atlas?

I have two GPS units,

1) Truck specific Garmin Dezl

2) regular Garmin Nuvi

The Nuvi I've had for years, and I like how it quickly figures out the quickest route.

The Dezl I bought in April, and it's glitchy, it does some crazy routing sometimes cause it thinks that some place, a section of I80 in Nebraska for example, is not a truck route and will route you down into Colorado, and will keep routing you out of Nebraska in a very determined way. Garmin has some work to do on the Dezl.

The Nuvi operates a lot differently from the Dezl. It's nice to have both, do I need both? No, I've been out here since way before there ever was a GPS unit.

I have two, cause I can.

 

There is a device that you can physically roll along the map, after you have set it to the map scale, and it will calculate miles. I forget the name though... There are analog and digital versions.

GPS and Google are the best and fasted invention I think. The miles are more accurate. The ETA is guesstimated now that hubby drives a lightbody truck, it drops speed pretty much in any mountain, hilly area.

We used a car Garmin originally, don't know if they even had truck specific ones back then. Followed route solution and used shipper/receiver info if given and stuck to large roads, vs small roads.

He has a Rand McNally now, the 720 version and it has its' quirks. It is better to find an address to key it into sometimes to get it to go the way you want it to go.

We also used the map atlas eons ago to figure mileage from point a to b and that to me was really a pain and so going. Used guesstimation sometimes to figure going from state to state time wise.

Google maps it great as long as you correct for the actual mileage you can go vs what a car can go and then add a 2-3 hrs according to if it were mountains.

I think if I had 2, I would go ahead and punch in the info to the second one and then turn it off till needed, then that way if a fuse were blown, it would have a charged battery.

 

Hi Mike,

Did you miss my earlier post? It is called an Opisometer. I remember playing with my dad's back in the early 70's.
