Just a word about their customer service... I flew into the Grand
Canyon this summer, after having criss crossed the country a bit on the
way out from the Northeast. When my wife and I left we had planned on
going north through one of the corridors over the canyon up to Bryce
but my Lowrance 1000 crapped out on takeoff, acted like it couldn't
lock on to anything.

We elected to go back to Alburqurque and went to a pilot shop in town
that carries Lowrance. Never did business with these people but they
spent an hour with me trying to reinitialize the unit. Then they
called Lowrance for me and handed me the phone. Bottom line - Lowrance
overnighted a replacement unit to me at the airport on my word that I
would return the old unit when I got back.

I love the 1000, and I'll buy another Lowrance product when the time
comes.
