              Best Overall: Garmin GPSMAP 78S Marine GPS Navigator

              Garmin GPSMAP 78S Marine GPS Navigator
              Garmin GPSMAP 78S Marine GPS Navigator
              Pros
              • Give a brighter display and can work in direct sunlight
              • The text-entry design can work on different conditions, even when the screen is wet or you’re wearing gloves
              • Helpful new interface for quicker navigating main menu items
              • Can float if you accidentally drop it on the water
              Cons
              • Low resolution and bulkier than the GPSMAP 78
              • The text-entry design is less intuitive than the touchscreens
              • Inaccurate elevation gaining reports

              Out of three versions of GPSMAP lines, we find the 78s is best for boaters and water sports enthusiasts.

              It keeps the same size as the original version for portability while inheriting a lot of strengths from Oregon, Dakota, and Colorado series. Two shining examples are the new customization options or the ability to utilize BirdsEye aerial imagery and Garmin custom maps.

              Meanwhile, there are some noteworthy improvements made on it.

              Such as the interface. We realized this new design is more convenient to quickly navigate main menu items compared to the other text-entry counterparts.

              Besides, the screen is leveraged to the transflective TFT model with a higher range of color. This means it will be much brighter and better invisibility, even under direct sunlight. Compared to the Oregon series, it’s more versatility.

              Whenever someone asks us for an affordable handheld GPS recommendation, we always tell them to pick the Garmin eTrex 20x.

              It’s lightweight, compact, and easily helps you navigate the trails.

              For kayaking, this will be a good backup in case you lose your bearings. From marking your starting points, see where you’re in relation to that, to showing the way back, it can work smoothly.

              Like other siblings, Garmin includes a basic base map in this unit, meaning that you can track what interstate is close to your position and what city you are in.

              But don’t be quickly disappointed just because it’s so useless. This GPS has the option to upload many FREE detailed topo maps and with 3.7 GB of memory, you can load up to 200 routes and 200 waypoints.

              Garmin GPSMAP 78sc
              Pros
              • Provide nautical charts – which the GPSMAP 78s doesn’t have – to give more accurate GTS
              • A handy wrist strap for hands-free capability
              Cons
              • The unit often locks up when navigating a route

              When boating and in need of directions, you know that you can rely on this Garmin GPSMAP 78sc.

              Why? – you might ask.

              Because superior to the 78s, it comes with nautical charts from Garmin which are really NOAA raster charts.

              This additional feature shows a more accurate ground track speed (or GTS) than the boat speed indicator, which is the result of the ASA104 test, not an opinion. Even though there will be some delay due to the way it calculates position, it’s unnoticeable.

              Two other big bonuses are the waterproof rating, which is IPX7, and the ability to float in water. With these extras, you can rest the heart to use it, no matter how clumsy you’re.

              How To Choose The Best Handheld Marine GPS?

              Screen

              • There are two key features to consider when you are looking at a handheld marine GPS screen – screen size and resolution.

              Size

              • First off is screen size!
              • This feature is dependent on when and where you’re going to use the GPS.
              • For example, if you intend to be on a kayaking trip, you will want something portable and easy to handle.
              • Smaller dimensions of the device results in smaller screen sizes but remember, don’t go for anything smaller than 1.5 inches of screen display because below that range, it’s really hard to see the data.
              • Now, what if you’re going to be on a medium boat with other screens around?
              • Size up!
              • A 4-inch or 5-inchscreen would be able to give you all the required information easily with no needs of squinting or leaning forward. Besides, it’s still portable to carry around like a breeze.

              Resolution

              • Resolution is the next thing to keep in mind but doesn’t worry, this feature is quite easy to consider.
              • The higher the indicator, the better.
              • One more thing you should look out for GPS screens is if you intend to use it under direct sunlight. As a matter of fact, when bathed in this environment, your GPS turns out to be harder to see what’s displayed on the screen, just like your smartphone’s.

              Water Resistance

              As your handheld marine GPS gets higher chances to get wet when it’s in the sea, water resistance will prolong its lifetime and keep it well-functional when you need it the most.

              The nearer you’re going to be to the water, the higher the water-resistance of your marine GPS:

              IPX0

              Don’t resist water

              IPX1

              Water-resistance from vertical drops

              IPX2

              Water-resistance from vertical drops + drops at 15-degree angles

              IPX3

              Water-resistance from spray up to 60 degrees

              IPX4

              Water-resistance from splashes at all angles

              IPX5

              Water-resistance from water jets at all angles

              IPX6

              Water-resistance from stronger jets at any angles

              IPX7

              Waterproofing in no deeper than 3’ underwater

              IPX8

              Waterproofing in over 3’ deep underwater

              FAQs

              How do you use a handheld GPS for fishing?

              Here is a step-by-step instruction to using a handheld GPS for fishing:

              Before going:

              • Check the fishing sites’ maps in your GPS
              • Mark your launch site, especially when you go fishing in a new place
              • Turn the “Breadcrumb” on to help you record your travel routes so if you lose your bearings, you can rely on this to find the way back
              • Ensure it has enough strong signals

              During the trip:

              Use the “zoom” option will help you easily read the maps

              There will be some fishing spots where you catch the most fish, mark them by labeling the waypoints. The same with potential fishing sites for more fish that you’ve scouted from other anglers (remember to make notes the reason you marked it)

              Before going back to shore:

              Check all the essential information recorded during your fishing trip to the device. Store it! Don’t forget to make notes about the overall results and conditions.

              How does marine GPS work?

              There are many satellites orbiting the Earth twice a day and each of them will transmit signals (including its time and location) to the ground equipment. Your marine GPS will rely on 4 different transmissions to help you to locate your boat position accurately.

              If you want to learn more, watch here:


              Are there GPS for boats?

              Yes, there are.

              A GPS device is workable anywhere as long as it receives satellite transmissions.

              But if you’re wondering a car GPS can be used for boat, our answer is “sort of”. As it’s not programmed with aquatic maps, it’s struggling to read it.

              How do you read a GPS?

              Watch this video to learn more:


              Does GPS work on the ocean?

              It’s dependent on which kind of GPS you’re using.

              As mentioned, automotive GPS can literally work over water. But as it’s not specifically programmed with aquatic maps, meaning that you can’t load shoreline maps, detailed depth, and topography, it’s hard to read it.

              Conclusion

              There’s no universal marine GPS that can work flawlessly for all purposes, which is the reason we take time to research, test, and categorize them meticulously.

              Finding out the best handheld marine GPS might be time-consuming but in the end, you’ll be completely pleased with the results. Hope this detailed guide has been helpful for you.
