# EggFinder GPS Screen - Help?

### Help Support The Rocketry Forum:

##### I don't do spirals
OK, let's make this clear up-front that it will be something I'm doing wrong or misunderstanding - don't spare my feelings.

I placed the rocket with GPS transmitter exactly 100 feet in front of the handheld portion, and my screen says the following;

WTF is this trying to tell me, and why do none of the arrows point towards the rocket?

I have tested this at 5 different distances, and it almost seems that it will point towards anywhere BUT the rocket.

What am I missing? I appreciate the help up front

The handheld receiver doesn't have a compass or any way to sense which direction you're facing. It only knows what direction you're walking. You can use the "Compass" heading however to tell which way to walk (as long as you know what direction North is).

Put the tracker a little farther out, and start walking. You'll get a relative bearing (with respect to the direction you're walking), and a compass heading (relative to North).

It seemed a little confusing to me at first, but after tracking my first rocket (which didn't go out of sight), it made much more sense. Now I find it super easy to use and very helpful. Use the compass heading to figure out which way to start walking, and then as you're walking, use the track (and arrows) to make slight adjustments to your heading and it will lead you right to your rocket.

May I then assume the easier option is to just plug in the coordinates into google maps on the phone & follow the phone directions?

Not sure if you have the bluetooth module but if so rocket locator app seems to work pretty well. Here is what I saw during a test inside my basement. Blue dot was Rx, red pin Tx

That's what I do. Or just use a simple GPS app like 'GPS Waypoint Finder', which works even without maps or data. It just uses the phone's GPS and compass to tell you how far away you are, and in what direction.

OK, top row:
Compass point of your rocket Seconds since last fix Compass direction that you're moving

bottom row:
Distance to your rocket Arrow and degrees Left/Right that you need to move to get to your rocket

And as has been mentioned, there's no compass, so the directions are in relation to the direction that you're moving. If you start walking/driving and follow the arrow in the bottom right, it will take you right to your rocket.

In your case, you probably walked away from your transmitter until it changed... it's telling you that the transmitter is behind you. "Your" position is only updated every 10 seconds, and you have to have moved at least 25' in those 10 seconds or it won't update your position. That's to keep you from walking in circles.

We don't update the internal GPS position if you have not moved at least 30' in 10 seconds. The idea is that it's going to tell you which way to go while you're moving... if you're not moving, it can't tell you which way to go. BTW, the next version of the LCD firmware will get rid of the arrows on the compass and track readings... they ARE kinda confusing if you don't know what they mean.

Then just was the number beside the D and gets your steps in.

Any tracking receiver should report the lat/lon coordinates at a minimum, so you have an actual location to refer to and can navigate with other tools if needed. Hopefully, your EggFinder has another screen that simply shows coordinates.

The arrows are nifty and fun to follow, but on both my Eggfinder and Featherweight GPS I just plug in the coordinates. That way I can find which road is closest. Just remember if you are going to a field without reception, to download an offline map (google maps app can do this).

Where did you get the Bluetooth? The HC-06?

What tracking / map app do you use? I hate typing in the ° “ ‘ is there an option that realizes these fields?
