Wintec WBT-201
Stuart brought a GPS receiver with him on our grand adventure, and that more or less got me hooked. I’m a big fan of having my photos location-tagged, being one of those people who, with some 5,000 photos spanning 7 years, can no longer keep track of where they were taken. I’m also sold on its value as a flying tool; it’s been enlightening to look at my tracks after IFR lessons (to see how badly I’m botching the wind correction in a holding pattern, for example).
I hitched my chariot to Vlad and rode him all the way to victory, graciously allowing him to do all of the research related to this particular buying decision. In this instance he did not steer me wrong, selecting the Wintec WBT-201, a rugged, vanishingly small logging receiver with just two buttons and no display.
First, the good things:
-
It’s like two cubic inches in volume. If that. It weighs nothing and you cannot beat the size.
-
I haven’t scientifically evaluated their 12-hour battery life claim, but it is quite acceptable. I charge it every few flying days, maybe once a week.
-
It has Bluetooth and USB.
-
gpsbabel can be harnessed to suck out the track data and erase the device.
-
It’s very, very good at maintaining a GPS lock in the face of lousy reception. I leave mine in the outside pocket of my flight bag, or the pocket of my trousers, in the mostly-metal airplane cabin, and it has no problem.
And of course, the inevitable accompanying problems:
-
It’s very bad at acquiring a GPS lock under poor conditions, and even under good conditions sometimes takes as long as two or three minutes. Worst of all, if you start moving before it’s locked, even under good conditions, you may never succeed.
Just walking around, holding it in my hand with a clear view of the sky, I had it fail to establish a lock during the entirety of a thirty-Earth-minute walk. (!)
-
Apart from this GTK software, which I haven’t even contemplated on OS X, there doesn’t seem to be a way to configure the device apart from their Windows software. The default settings aren’t disastrous, but they’re definitely not perfect.
-
The aforementioned Windows software is a disaster. It is dangerous at any speed. Use it to set the few options whose meaning you can decipher and close it immediately before your brain atrophies.
-
In fact, it is the documentation for the software which causes the most harm, because it is total garbage of nearly zero value. It reads like a motherboard manual, full of helpful information like this complete explanation for the DGPS Timeout value: “DGPS Timeout”
If any of the options were explained at all, the software would be merely bad instead of useless.
-
Every once in a while I get a point or three way off to the side, maybe 30 miles from where I actually am, and then it settles down. This seems to happen chiefly when I’m walking around and just establishing a GPS lock. It’s confused momentarily, and doesn’t seem to realize that those points are low-confidence. Fortunately, these don’t seem to happen if I let it get a solid lock before moving.
gpsbabel has an option to discard points below a certain confidence threshold, but either the device doesn’t produce this data, I don’t know how to enable it, or the gpsbabel reader doesn’t know how to parse it. If I had to guess, I’d wager it’s the second.
On balance, I recommend it with relatively few reservations. If you can wait 3 minutes to establish a lock before you move, and don’t mind editing the odd broken point out of your track, it is an excellent device that will maintain its lock in the face of very poor reception. I think it’s hard to do better at any price, and this is sub-$100.
Given its long battery life, tiny size, and negligible weight, it’s the kind of device that you can turn on, toss in your flight or camera bag, and forget.
