Our Review


Made to withstand the elements and the test of time

Durability matters a whole deal when it comes to fish finders. Nobody wants to buy a product that will sooner or later prove to be unusable, so reliability is a detail to consider. Since this is a waterproof device, it speaks to the needs of people who do sailing and whose electrical devices frequently get exposed to water.

Marine fishing sure isn’t easy, particularly since users tend to go out at sea and risk losing their way. GPS receivers are always welcome from this point of view, and this Garmin unit comes with this exact feature. The GPS of this model is capable of locating the position of the user in a timely and precise fashion.

GPS, maps, and coastal charts

GPS isn’t good for all that much if buyers can’t use any coastal charts or maps. Fortunately, this device has both. Marine, topographic and road maps can be added on account of the microSD card. The card is placed inside the waterproof compartment, therefore allowing users to sit back and relax, and enjoy their trajectory. Preloaded BlueChart g2 cards can be plugged into the device. Furthermore, the GPSMAP 78sc supports BirdsEye Satellite Imagery.



Get all the perks of Garmin Connect

Connectivity is an innate characteristic of this model, as it can be utilized for sending tracks to others users, via Garmin Connect. Sharing experiences via social networks can also happen with a single click.

Judging by its reviews, it looks like this is the best marine GPS from Garmin, as it’s been praised for being lightweight, reliable, and capable of an excellent performance. Above all it is considered to be remarkably dependable. Most buyers speak highly of the built-in electronic compass in this device, as it has been proven to calibrate quickly and to react fast to movement. While the complexity of the menus might pose a difficulty to some users, the advice of other customers is to keep exploring in order to discover extra functionalities.



Taking into account the specs and the amount of appreciation it has managed to gather over time, it would not be far-fetched to say that this might just as well be the best waterproof marine GPS on the market today.
