The other guys Astro was telling us north was to our east....I had a regular compass and I followed it to come out on the road. If I had used his Astro reading I would still be lost in the woods.....
This was due to operator error. You need to calibrate the compass before the hunt. I am pretty sure it triangulates based on the satellites it connects with on that particular hunt. I mistakenly thought that once I had calibrated the compass on a particular piece of land, that it would remember the settings. I learned the hard way, it does not work that way. Just recalibrate prior to each hunt, and you will not have any problems.
I agree that there is plenty of room for improvement. That's why I run both the DC-30 and the radio collars.
That said, to date, I have had more issues with Tracker brand radio collars, than I ever have with the DC-30's. For radio I run Quicktrack, and some Mike Kelley collars, and would not hesitate to run Marshall, or Wildlife. I will not buy another Tracker product.
