You can get a decent polar alignment with just a compass and knowledge of where you are.
First, set up your mount so that it's altitude is set to your latitude.
Then, make sure the top of the mount is level. (Yes, it is not absolutely necessary that your mount be level, but if it is not, then the latitude setting will be off, and every adjustment in one axis will adversely affect the setting in the other. ----- And there is no reason to start with the mount anything but level.)
Now, using a compass, set your azimuth so that you are pointing to TRUE North (not magnetic as on a compass----if you need to know how to correct a magnetic compass reading to true, just ask).
Now, do a simple drift alignment from PHD2.
If this is not a permanent installation, before setting up, be ready to mark the precise position of your tripod legs. If you are on grass, put down three pavers to hold your tripod, and mark those pavers. Next night set up in exactly the same place, and do a drift alignment.
Another trick.....after you have aligned as well as you can with the compass, and aded the altitude, put the scope in "Home Position" (usually at 90 d dec and counterweight down). Start the system and do a "goto" to a known bright star 40-60 degrees above the horizon in the east, near the celestial equator. When the scope goes there, center the star USING THE ALTITUDE AND AZIMUTH ADJUSTERS before doing your Drift Alignment i PHD2. This may save you some adjustment time. (It may not be possible with some mounts.)
