Navman R300 GPS Speed and Distance Sport Watch

Poor performer

I bought this unit to track how far I travel while walking. The

first unit received had bad segments in the LCD. Amazon

quickly sent another unit that did appear to work.



This unit takes a long time to find sattelites. Several times

it never found ANY under clear blue sky. It just turned off

after 10 minutes. It would lose signal frequently.



The deal breaker is that when it loses sattelites it will not account

for distance during the lost signal. Lets say you are walking/running and the unit is logging distance. For a 10th of a mile it loses

sattelite. When it gets sattelite back it starts logging

again from the new point. But it does NOT add the distance

you traveled while the signal was missing. As if I teleported

to the new location. Useless.More detail ...
