USB Rechargeable 65-Channel Mini GPS Location Finder

Pros: Small
Simple
Auto Start
Programmable
Great Price Point

Cons: Feedback while running (or not)
Status indicator?
Instructions

Other: Good value, good item, good features, well worth the 26 dollars. Was going to build an equivalent unit from an old GPS engine, PIC microcontroller, JPModule / CF memory, but little point now. Another winner from DX!

Pros: It's very precise and acurate.
It have various modes of logging (configurable by the user via PC - need the included software).).

Cons: It's not stand alone (it needs a USB power source).

Other: Thats realy cool. Pay attention: It is NOT stand alone!!! The reason that it have an internal battery is to retain the last information obtained to make fast startup in the next time you power it on.

Pros: You can decide how you want to supply power. I used 4 800mah eneloops in a usb power pack and the runtime was just over 16 hours, a draw of roughly 50ma at 5v, or 250mW. With 4 AA 2000mah eneloops, the time should scale up to almost 2 days. Logging once per second, there is enough memory for 27h46m (100,000 points). Up that to twice per minute, and it'll log for a month. You can also set it up to only log over a certain speed, or after a minimum change in distance from the last point. I have gotten a lock in <60s every time I've used it so far.

Cons: Accuracy is certainly good enough, but not quite as good as my phone (galaxy nexus). For something requiring precision <30-60', this may be a concern. For those who just need to keep track of general whereabouts, it's just fine.

Other: A great buy. Cant wait to try it out on my RC plane, or mail it to a friend and see if I can track the mailman :p
