I want to give a special thanks to Boris du Reau at Bear Altimeters! He has responded quickly to all my questions even though he is many time zones away. Also, he quickly replaced a faulty unit. Even though it was sent from overseas it arrived quicker than if it had been sent from the States! The new unit (very small) works great!
