Hey now,
I guess I'll be the one to admit I have actually USED the E6B function on my Citizen Navihawk. Not for flying mind you. For commuting (driving) to the freakin' outstation to get back to my airplane to start the week. Let's see, 89 mph and I have 327 miles to go that's uhhh... lemme see here.... uhhh.....And yes, minutes counted.
The downside to the Navihawk is that is doesn't light up, and I had to carry the manual around with me for a month to figure the thing out. I DO like the 3 alarms though. I wish it had more. But my new cell phone filled the gap there with it's built-in planner function. I do like the separate little dial for Z time too - that way I can keep the digital window set to Calender. I am retarded when it comes to remembering what day it is....
