I've got a Brunton 8099 pro; its crap in my opinion. huge bubbles formed on multiple occaisons, requiring replacement. the baseplate quickly faded to unreadable, the needle stuck, the bezel so loose it turned on its own. customer service was great and they always sent me new parts. finally I just shelved the thing and go with a $10 silva from Walmart. I've got a few in different places and never been happier!
