I would like to extend a great big THANK YOU to all who responded to my questions.
Frank, I did consider the Magellan because I already have the hand held portable that I use for marking my fishing holes.
Kenny B, I was looking real hard at the 3790T.
I have read revues till I'm blue in the face
. I finally called Garmin and talked with them about the 855T and the 3790T. He told me they have a new model out, 2460LMT. Similar to the 3790T except no glass face which was fine with me cause I have a habit of dropping things. The big plus-- $100 less then the 3790T and it has voice recognition. One of the main things I wanted. . Decision made. I ordered one. I thought about the new one they have where you can enter length, width, height, etc. I really don't don't think it's necessary. At least for me.
