Anyone use a GPS Data Logger ?

Hi,

I was just wondering if anyone had used one of the above for hiking or anything. I got one a few days ago and have been testing it... and I'm really not impressed ! I got a GT-730FL-S which uses the supposedly good Venus 6 chipset but my results have been all over the place and the device just seems to loose its GPS lock for no reason.

The image below is a quick test I done today, The blue line is the logger and the thin yellow line is my galaxy s3 with a GPS logger I downloaded. I turned off wifi and mobile data to try and limit any other info it was using.

The phone managed to track me very accurately (except for the start in the trees, but I started both the loggers indoors so I expect some errors from that). But apart from that it followed me to within a 2 or 3 meters, even logs where I crossed the road, As you can see the blue one form the logger is a complete mess and pretty worthless... then stopped for the rest of the walk for no reason, wouldn't re-lock for the rest of the 10 min walk.



So if anyone has used any loggers in the past I would appreciate any input. Are they all this poor or did I just get a faulty one ? Unfortunatly I couldnt find a lot of tests online for them to look at and I don't really have anything else to compare it to.

Thanks

Gordon.

Thanks for the replies so far, I do have a good app on the phone for logging but I would like a good hardware logger instead. I want to use when I go hill climbing to see what route I have taken and so on. I would rather use a hardware logger than my phone to save battery life and the phone is usually kept somewhere safe like under several layers of clothing or in my bag if I am climbing to keep it safe. The hardware loggers are also usually small enough to get clipped on to the cats collar - and I would be interested to see what hes getting up to.
