• Reviews around 76 (5.00 of 5)

    Garmin GPSMAP 78S Marine GPS Navigator and World Wide Chartplotter (010-00864-01)

    • The case seals on this unit definitely don't seem as durable as the 76 and I think that's likely the issue many people are having with leaking
    • While it does, as advertised, lock on to satellites slightly better inside buildings and other obstructions, compared to the 76 it also bounces around a lot more when it has good reception (it's worth pointing out that both continue the trend from my previous GPS72, which didn't have a high-sensitivity antenna and so was awful under any kind of tree cover, but would get a pretty accurate and repeatable point with only four satellites).
