Explanation of what you are buying
I have published these books in a manner similar to shareware. You can download both books for free, there is no physical copy. I am asking for a voluntary payment of $5 for Basic GPS Navigation and $10 for Cockpit GPS. However, I will gladly accept any amount. This is less than a couple of beverages and I hope that you will find this to be a bargain for the amount of information available in either text. Publishing in this way allows me to publish internationally and create updates. This also provides you with instant gratification and the ability to see if the material is what you are looking for.
Satisfaction is guaranteed in that you can read the material first and see if it is of use to you.
