wife bought the vpg unit last year, she thought it would be easyer for her to read than her f-12, it is easyer to understand the display if you have never used a flasher unit before, she soon found out if you get around a lot of other flashers it cant handel al the interferance, by the time you ajust it all out you lose your ability to see your jig. also when you put it in the ice mode to keep the lcd display warm the battery only last about 6-7 hrs, if you dont use the ice mode you get about 8-10 hrs on a charge, on the + side it is nice an compact, easy to read, light, and charges in about 2 hrs.
