Ive used my Garmin 195 for several years flying pipeline patrol, and it has never let me down. I've got all my pipeline routes laid down in the track function, and uploaded to my PC. I just download the track I need for a particular route, and that, cross referenced with the actual company maps I carry, give me all the nav and line information I need. The ground crew guys with the pipeline companies are carrying GPS units now, and they like the fact that if I find a leak or something else that needs their attention out in the middle of nowhere, I can give them exact coordinates as to where to look. The 195 has gotten me through some pretty rough weather situations, also. Even made my own instrument approaches into a couple of uncontrolled fields along the way for just such weather emergencies. I know that there are other units that have come out lately that have all the latest bells and whistles, but in my opinion, the 195 is still one of the best units out there, and they can be had at a very reasonable price nowadays.
