In overland travel it is essential for one to know where they have been and where they are going. The DeLorme Earthmate LT-20 is the perfect option for a person on a tight budget. At a minimal $60 it has the potential to be a very versatile tool. From the options for topographic maps to the more advanced travel atlas; the Earthmate proves to be rather indispensable in the back country.
My friend Abraham and I tested the unit through varying types of terrain and weather conditions. The only other product I needed to buy was a power inverter from my local auto parts or marine supply store for a minimal cost, to run the lap top. However we found out the GPS unit draws little to no power or CPU usage in operation; which was an added bonus.
We started in Pullman Washington and decided to head South East toward the Snake River. The unit had no trouble connecting to the Global Positioning network while navigating steep canyons and river basins. It did have a bit of trouble when it encountered a change in the map accuracy. We were using the point to point direction finder when it suddenly had a minor spaz attack and repeatedly told us that we were off course or in fact off the road. We were impressed that it recognized that we were only feet off course and not entirely lost. There was a minor discrepancy in the original road location and where the road lies today so the unit thought we were off course.
Another thing that is important to note, is the unit’s inability to “calculate” easily from town to town. The simple solution is to use an address or a specific location to simplify the route. The mapping software has restaurants and gas stations marked so it is easy to select one of those for it to calculate the fastest route.
The amazing ability for the GPS unit to accurately pinpoint a location within about two feet was spectacular. The route planning software is not necessary for backcountry travel but still knowing where you are in relation to rivers, highways, cliffs (if you are using the Topographical application) and gas stations is rather indispensable.
Overall we were so impressed that Abe went and bought one for him self. The maps are easy to read and well marked including forest service roads and national/ state parks. Furthermore the turn by turn direction voice is fully customizable from the generic Stephen Hawking voice to a very sultry female robot. We both found that map reading is much easier to understand when you know exactly where you are.

I can second all your experiences. I recently took a trip in another vehicle and did not have the laptop and Earthmate running. I missed it sorely while navigating back well after dark in unfamiliar areas. It was not intentional, and left me outside my comfort zone for a time.
I like my comfort zone.

yeah its a good little tool. im glad at least some one read this.

Hey, there are plenty of people here who every post. I suspect quite a few of us just absorb the knowledge and move on. I know that this thread has gotten me to think about taking an old Tablet PC I have laying around and see if I can make it into a good GPS system.

We need a short hand way of just knodding in agreement. A grunt button if you will, that doesn't require actualling posting.

Thanks,

HAHAHAHA we so need one of those, yes you are right not everything is replyable but it is nice to hear if its useful or not. i want to do more testing but there arent too many roads out here in the boonies to explore.

BTW shhhhh i think overland journal is doing a similar test for thier next issue, you didnt hear it from me. shhhhh

I just ordered one of the Earthmate GPS LT-20's. I already had the software, Delormme Topo USA, which should work with the unit.

I ordered this complete package and bought a friend's used laptop to test it out. What I need to do next is build a mount for the LT to fit on the base where my 3000MT used to sit.

I used the program on the way into Toroweep on the Pres. Weekend. My girlfriend found the topo feature handy for practicing for her up-coming Orienteering class module.

I find the need of a mouse to be awkward in a moving vehicle. I plan to look into other options. It may fine once the LT is mounter, dunno.

What I do find awkward in the program itself is that the tools feel a bit klugey compared to both the Garmin and Lowrance map programs.
