" Review: A remarkable navigation tool - I read the reviews before purchase and must say that I do not agree with the grouse regarding operating the device. OK it is not all intuitive but the instructions are clear and easy to follow. One just needs to learn a few commands to handle everything. I am not planning to test it in water as I do not regard it as waterproof but nice to know just in case. I would like a longer strap so that I can wear it around the neck and maybe tuck it inside a waterproof. If you would like depth reading, you would need to wire it to a transponder. A bit pointless, one might as well have a dedicated instrument. What it does do it does very well. It even has a timer if you are starting a race. Check it at the 5 minute gun and you will have an accurate start. I think that the world map that Garmin uses is rather old and inaccurate! I was puzzled why I left a main road according to the GPS but was indeed on it. Reason - an airport had been build where the road used to be - rather a long time ago!! I hope that the dedicated maps are more accurate. Review: 4 years and gong strong - I have been using this about about 200 days a year in the field since I got it several years ago. I put a screen protector on it, and change it out once or twice a year. I use this all day everyday for field biology work, navigating 2.4km transects, marking data points, etc. It took some getting used to Basecamp, and I still use Mapsource for some stuff to work with files, but the Garmin software is WAAAY easier than the deLorme stuff. I got a Delorme Earthmate PN-60w for a backup/replacement when my old Garmin 76 got run over, and I found the PN60much to difficult to figure out, and the software was crazy. I got both because fo the ability to download satellite imagery to them. The Delorme software is to tedious, too many layers. Garmin you just say high resolution, and go for it. The Garmin download speeds are SLOW. To get a 150mile by 100 mile area at high res, expect to spend a day and ahalf coming back and clicking on the next section you want download. a 200mb file will take an hour or so. I have tried on faster connections than my 5mb/sec setup, and it is still tediously slow. Pros-Indestructible(mostly) I like the 10000 waypoints, I put a 32gb memory card in there and have about 20gb of satelite imagery downloaded onto it. I like the old style push buttons I go a day and half on my rechargeable AA batteries that I charge on my little solar charger I think you can go 2 days on regular AA's, though I use the screen saver that turns the screen off at 15sec, 30sec, 1 min, or 2 min intervals Pro and con-customizable setup, you can make it look like your old style garmin format for those who are too used the 76, but it is somewhat tedious to do that, and it is a little too easy to accidentally hit reset to factory-that does not erase your data, just your page setups, map setups, etc. Cons-Garmin sat imagery is slow to download, requires their $30 a year subscription service. OH, and, if you have sat imagery on your computer that you downloaded while your subscription was in effect, once it expires, you can't move it back onto your device. They want that $30 a year. Eh, cost of doing business for me, maybe not so appealing to a recreational user. ## Features - 2.6-inch TFT LCD display.

Once you start tracking the MOB, a path is outlined as to where you are relative to the original mark, plus the bearing back (or reciprical) and distance back to the mark. The same is for using a waypoint. Once the waypoint is set, you can go to it using FIND button, click on the waypoint, hit GO and you get the same path shown plus the reciprical bearing and distance. **Q: Does the basemap that comes with it show the marine topography?** A: No, this device is meant for land activities not marine although it display your location, distance, etc. **Q: will the 78s do loran to gps conversions** A: No. I don't know of any conversion programs ## Customer Reviews ### ⭐⭐⭐⭐⭐ A remarkable navigation tool *by R***B on March 26, 2013* I read the reviews before purchase and must say that I do not agree with the grouse regarding operating the device.

Eh, cost of doing business for me, maybe not so appealing to a recreational user. ### ⭐⭐⭐⭐ Great GPS for Dual-sport use *by T***N on December 19, 2013* I chose this "marine" GPS for use on my motorcycle over the 62 because it has the robust 4-pin power connector. The buttons on top aren't terrible - but not ideal either. The unit is quite accurate, even in deep canyons and with thick canopy overhead, I've never had it not know where I am. The screen is clear and quite readable even in bright light. It takes the beating of handlebar mounted desert riding very well. I've crashed on it pretty hard and had it fly out of the RAM mount to find it 15 feet away. I like the power options - being able to grab it off the bike and take it hiking is great - also nice peace of mind that I'll have a GPS if I have to leave the bike due to malfunction. The battery life on 2200mah rechargeables is about 1.5 - 2 days of use. There are a few downsides which made me give it 4 stars. There's no way to make the backlight stay on, can only keep it on for 2 minutes at a time. Annoying since I also use it as my speedometer. The maps are expensive, and you DO have to buy one to get any sort of functionality from it. There are sites that make good, free, routable maps but the Garmin maps are not cheap. The way it breaks up routes and tracks is confusing and unintuitive. And finally - this applies to the base model only - but when you stop, since there is no compass your arrow spins around in a circle instead of staying the direction it was pointed last, making finding your way at intersections difficult at times. I can't possibly see a reason for this except to make you wish you'd ponied up the extra money for the unit with the compass (which I do). ## Frequently Bought Together - Garmin GPSMAP 78S Marine GPS Navigator and World Wide Chartplotter (010-00864-01) - WINDFRD Aluminum Fish Finder Mount with 1.5" / C Size Ball, Medium Arm Marine Electronic/Depth Finder Mount for Boat, High Salt Water Resistant, Compatible with Garmin, Lowrance and More - Garmin Heavy Duty Transom Mount with Spray Sheild --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/1161593-garmin-gpsmap-78s-marine-gps-navigator-and-world-wide-chartplotter](https://www.desertcart.pt/products/1161593-garmin-gpsmap-78s-marine-gps-navigator-and-world-wide-chartplotter) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-04-24*
