    • NMEA output Capable
Style: Preloaded
Garmin has never been good at describing features or how to use them on their GPS systems. It is certainly the case for this very capable handheld GPS device. One must learn by scrolling through the menus and getting your device to do what you want it to. I got this Garmin GPSMAP 79sc to replace my 76Cx which, after years of using, had a simple battery compartment issue I was unable to fix. I had set up and used my old Garmin to, among other things, communicate NMEA streams of data to my autopilot on my sailboat. I shopped online, even at the official Garmin site, and looked for this feature among GPS handhelds with no luck. I even went into a retail store to talk with knowledgeable salespeople as to what product would do this. No luck. But while having the 79sc in my hand, I noticed it had the Garmin round plug port for power and I/O which wasn’t even mentioned or shown in online descriptions. The Quick Start booklet which came in the box said nothing about the port, and the owner’s manual, which I had to download, had little. I took a chance and bought it. Turns out I could get this working like my old device by exploring the menus. Not much help from any written direction provided by Garmin. It must be a legacy feature not used by many today. The 79sc has many features, some useful to me and some not, but it is very capable. It determines position faster than my old, almost instantaneously. The compass feature is handy and works by some technology alien to me. Probably magic. And the unit I got, being preloaded with coastal charts, is nice. Display is nice. The scrolling buttons are a bit touchy. I’ll wait to test out its waterproof and floating capabilities until I accidentally drop it overboard. So, if you want a very capable handheld GPS, try the Garmin GPSMAP 79sc. Just be patient, explore the device, and get to know each other together. ... show more

    • Quick ship - “Fresh” unit
Style: Preloaded
Unit had the latest software loads including system software and BlueChart loads. Very quick delivery. Nice! This was purchased as a backup unit for one bought a year ago. Still learning how to use the routing and recording features. It has not been completely intuitive but the manual full download helps. Accuracy & startup time are excellent. Predicted battery life of 19 hours seems accurate but wish it was 24 hours…. A very solid unit. ... show more

Absolutely horrible tech. I’d expect this level of technology 20 years ago. Actually the titanic probably had better tech. Zero intuitive effort in its menu design. STILL. After all the complaints from previous models they did NOTHING. No touch screen on a screen the size of a 1990’s cell phone so I guess it makes sense. Lags like nothing else I’ve seen before. The $100 hiking versions and their watches are worlds better but you’re walking. Or biking. I mean you’re on a boat. You need quick updates and fluidity no pun intended. Oh yeah, no inland water maps. No lakes. No rivers. About $100+ a year for that luxury. Uses AA batteries for better or for worse. If you still use Garmin to drive around this device is for you. I know this isn’t a replacement for dedicated nav, but for casual boaters, club renters, and kayakers who just want a mobile nav device for unfamiliar areas this thing fails. Get T-Mobile with Starlink on a used waterproof phone or get a case and download an APP. Most of them give you about everything you need for free but no more than about $50 a year for the good stuff and updates. How is Garmin still in business with this crap??? ... show more

    • Prefer Navionics maps on phone better.
Style: Preloaded
Multiple reasons I don’t like this unit. Doesn’t hold micro as card well, falls out. Can’t load and use inland charts and use preloaded coastal charts together, have to toggle between the two. Not a huge problem unless entering a river from bay, sound… Don’t like the chart, prefer Navionics charts better. I knew it had a small non touch screen before purchasing, but really displeased with not having. ... show more

    • Marine set-up not for the technically challenged
Style: Preloaded
I had to ask the gps sales person at Hamilton Marine to set up the charts for marine operation. It is not easy. However, since then, I have been able to use and enjoy the features of this gps. I use it planning and tracking multiple weekly ocean kayak trips of 6-15 nautical miles and 2-5 hours. The map does not label smaller islands which is a problem so I always have a paper chart with me. What is excellent is that I can read the screen, mounted on the deck, in all light conditions. Lithium batteries provide me about 15 hours of tracking with this gps. The GPS is exposed to weather and salt as I have it on a Garmin portable mount on the deck of my kayak so I rinse it under the faucet after each trip. After 2 years of use - May through November - it still looks new and has never leaked. I am very happy with this gps. ... show more

    • Good hand held GPS
Style: Preloaded
I didn’t like the Garmin 79sc because it would not allow staying on longer than 2 minutes so I sent the Garmin and ram mount back. I got my old 478 working again with a new antenna and again have a chart plotter on a ram mount that stays on. The need to wake up the 79sc every 2 minutes or less was the only issue. I understand the reason is the preserve the battery charge since there is no option to plug into the 12 volt boat power. The functionality of the 79 sc would be great for a portable gps that you could power up quickly and perform numerous functions, and then turn off. For any activity that allows you to slow up or stop to use the gps I’d recommend this unit. For a chart plotter on a boat without a second person to operate this unit, it’s too inconvenient to slow to idle to check your position and depth especially if you operate in shoal water. I got lucky that a new antenna revived my discontinued Garmin 478. I will rinse the salt water off the unit and detachable antenna connection every time now. ... show more

    • Great back up GPS for boating
Style: Preloaded
I bought this as a backup to the main navigation unit on my boat. It's packed with a lot of features, but marking waypoints and navigating to them is just a couple of clicks. I turned off my primary plotter yesterday while fishing offshore and used this to get back to port. The compass navigation mode is the better of the two IMO. The charts are detailed enough to use this unit as a main GPS unit if you also want the ability to use this in other environments such as camping. However, you'll probably find the screen too small when there's bigger units available. ... show more
