My uncles did it last night Hobo but it was only because his female was treeing in a hole. The difference is the communication page showed no GPS signal bars but full strength collar bars. The ? even was moving around on the map page some like the dog was moving, such as you describe, but the dog was actually still in the hole. Just a minor nuance of the system. Track your collar and then toss the collar in your basement where it can't get GPS telemetry from the satellites. You should have full signal strength but no GPS signal bars on the collar. You will get a ? mark and poor GPS warning. That ? mark will also move all around the map page making it look like the collar is moving when it really isnt. Be sure not to scroll out too far on the Astro or you will not see what I am talking about. The further "in" you go, the worse it looks.
But.............. you are saying you have seen the ? mark but yet had signal strength bars on the communication page with both the GPS and collar. You have to remember, when the Astro looses signal or GPS from the collar, the Astro does not immediately tell you that. Put your Astro on a 10 second update rate and look at the communication screen with full bars. Now turn the collar off and see how long it actually takes the signal to finally dwindle away on the screen. Maybe when you had the ? and looked at the communication screen on the Astro, the signal bars had not had time to fade out. It is kind of like the Astro, if it has signal on a collar then looses it, will sample the collar at your update rate, and then each time an update sample happens with no collar signal present, the signal strength bars will dissappear in increments until they are fully gone and the Astro then will warn you of that condition on the screen and audibly.
