REVIEW UPDATE...after the below issues and two software updates later, Neptune is now working without fail, EXCEPT for the difficulty in hearing over wind noise still. With the protec helmet, Neptune installed inside next to ear, audible cannot be heard with high speed/wind. Although Protrac can. Neptune says they are worried about hearing loss liability...and what, Protrac isn't? Two Neptunes have gone haywire, pressure sensor, thought it was jumping, apparently. Neptune's only 2 months old, but they expect me to ship it back at my cost, if it peturbs me, its probably not fair, compared to other customer service policy. ps.Not sure if L&B charges shipping 'cause never had any problems with IT!
