* The official weight of the BrailleNote PK is 0.9 pounds. The Blue Logger is only a few ounces so it comes in just under a pound in total. * The official stats on the Trekker say the following: * Total system weight: 600 grams (1.3 lbs) . * That is Trekker as a stand alone unit. I don't know how much more it would weigh in the Maestro configuration, probably about the same. * The BrailleNote PK and Blue Logger GPS weigh one pound. The Trekker weighs 1.3 pounds and the VoiceNote and GPS weigh 3 pounds. The BrailleNote 32-cell and GPS weigh 4 pounds. Michael G.
