A favor Magic? Can you test the bonehead current draw when forgetting to turn 'em off and pinging the Milky Way all night? Since I'm the weakest link. For me that means 16 LI AAs per trip so about a half pound of batteries... plus FISH LO-K-TOR. Thx, db.  That makes sense to me and is exactly what I do each trip...and I didn't hear the low battery alarm before morning too...  :)

That is why I prefer a couple of sets of batteries rather than one large set. 

Any one catch what I used for a resistor in the post below?
