I'm thinking of gettin the 78sc for a back up unit. Will I have to get any maps to make it useful on a California to Hawaii sailing trip.

I have the unit which I use for kayaking. The world map that comes with it is laughable. You will need to buy a chart for that area. It is a well made unit which I am pleased with however.

The Gpsmap 78sc has charts for Ca and Hi. Only the sc, not the other models.

maps are easy to download into pn-60, i use delorme Topo USA and then choose a grid they have laid out and then off it goes to the gps unit, not much trouble at all. Don't have to be computer geek to get it done. Reception on gps is awesome, i have left it in my pocket under heavy tree cover and it still recorded my tracks. Very happy with this unit.

The unit comes loaded with coastline maps of the eastern seacoast but no fresh water maps. They can be bought and loaded seperatly by buying the coresponding chip for the frshwater areas you want to navigate. And yes it does come with a transducer.

Go and check out the manual, there must be an SD card slot. Otherwise load the map via the computer to the internal memory. Maps are good value for the money.

As long as your Lowrance has NEMA connections,and you properly wire it,as mine took a bit to get right.Mine is interfaced with a Garmin,and as soon as it finds satalites,your ICOM will display "GPS" and will also display gps cordinates,time,etc.It took some reading of the manual,but I will never go back,I love the fact that I have one distress button to hold in case of emergency and help some shape or form will come.Oh ya dont forget to register your boats name..etc..so you can get a MMSI # (its free)and program that # into your radio,so when/if you need to use the DISTRESS button the Coast Guard know exactly who's calling.Good Luck As long as your Lowrance has NEMA connections,and you properly wire it,as mine took a bit to get right.Mine is interfaced with a Garmin,and as soon as it finds satalites,your ICOM will display "GPS" and will also display gps cordinates,time,etc.It took some reading of the manual,but I will never go back,I love the fact that I have one distress button to hold in case of emergency and help some shape or form will come.Oh ya dont forget to register your boats name..etc..so you can get a MMSI # (its free)and program that # into your radio,so when/if you need to use the DISTRESS button... » Read More As long as your Lowrance has NEMA connections,and you properly wire it,as mine took a bit to get right.Mine is interfaced with a Garmin,and as soon as it finds satalites,your ICOM will display "GPS" and will also display gps cordinates,time,etc.It took some reading of the manual,but I will never go back,I love the fact that I have one distress button to hold in case of emergency and help some shape or form will come.Oh ya dont forget to register your boats name..etc..so you can get a MMSI # (its free)and program that # into your radio,so when/if you need to use the DISTRESS button the Coast Guard know exactly who's calling.Good Luck « Show Less

Not positive if will work in your 182 but it should. It shows detailed navigational waters wherever the corps of engineers have done soundings. It will also show depths and snags as long as it's in navigable waters. It does show lakes and shorelines in detail. I updated my software when I got my chip and have really liked the map details. I borrowed a chip from another guy on the docks before I purchased mine. I think he had a 182 also. On positive though. Hope this helped.

This unit will not work to contact CG. They don't monitor these UHF frequencies. Your smartest bet for SOS protection in the ocean kayak scenario is a Personal Locator Beacon. It communicates with satellites and uses GPS to mark your position to rescuers should you initiate a distress signal. They cannot be used for routine communications. ResQLink makes one PLB model. They run about $300. One time purchase, no additional yearly fees or anything. Battery is good for about 10 yrs. If you're solo on the ocean or in the backcountry these make great sense and are cheap insurance for your survival. This unit will not work to contact CG. They don't monitor these UHF frequencies.

Hello. unfortunately the maps will not work since they are programmed for the U.S. the unit will work, but the maps wont.

Absolutely, Mine came with all North American maps installed and navigates fine in Canada. One person said it Wouldn't work on Kauai in Hawaii but mine worked fine on Oahu and the Big Island so it is possible the Hawaiian maps weren't installed on that person's Garmin

I do not know for sure. When I first got it it seemed to run fine with US and Canada base maps that came from factory. I updated those using the Garmin updater software tool. I put a 4gb micro SD card it it from my old unit but have never seen any indications that I really needed it. Try the Garmin website if you need more info. I am very happy with the thing. Bigger screen and faster, better menu system them my old unit.Good luck

If you have a Garmin 78sc, this chip is preloaded . If you want inland lakes, talk to Garmin to find the proper chip. Amazon doesn't tell you this. They just sell you the un needed chip. Howard

I just purchased this at the Navy Exchange hawaii for $33. If you know anyone with base privileges it might be worth asking them to pick one up for you.

Klamath,I sympathize with you. I also made a mistake by attempting to update the firmware on my Roadmate 6000T which was in pristine condition and worked ok aside from the map being outdated. The thing crashed after the firmware update and would not start. It has been sent back to a repair center in Smynra, TN for a refurbished replacement, I just hope I don't get a crappy old thing back like you did, that is disgusting, IMO a refurbished unit should be like a new unit and not bashed up as you described, Magellan's after care service is terrible !!!

Linda, Sorry this comes so long after you posted. I was just looking at micro sd cards and saw this. The 530 HCX is the best choice. If this person spends time in the outdoors with other folks, he will use both the GPS and the radio. It also has all the NOAA Weather radio stations. Hope this wasn't too late! 2wltime
