![]() For route planning and waypoints I've been using Geo Garage with great results on the GPSmap 60. Question: I have a Garmin GPSmap 60CSx that just became my spare and my GPSmap 78sc just came in a few days ago with bluecharts g2. So, my advice to those using a Garmin 78 is to double check to be sure every route does indeed have all its wpts.Keith. Occasionally, the 78 will have the uploaded wpts and route names, but will not have ANY wpts associated with a route name. The BlueChart g2 microchip is very good-not perfect, but very good.When I load my Garmin gdb files of waypoints and routes onto my 78, I must check every route to be sure that it has the proper wpts. I've had considerable trouble with my Garmin 78 w/ BlueChart g2 microchip. I plan on running a small 12v battery pack to run my nav lights, bilge pump?, cell phone charger, and gps the entire length of the race.Joe. But the 62sx is a very good GPS, we have those at work.I've heard too many stories of GPS units failing in saltwater conditions, mainly due to saltwater and humidity intrusion due to changing batteries. I think the C means Camera in the 62 model.īeware the 62 regular model doesn't have chip capability. Very expensive.What is wierd is that the S and the C can mean different things in different Garmin models. Like I said, I don't necessarily need the compass.78sc has a compass and the charts built in. It is a 3X upgrade from my old non-color 76map models in that it is a color screen and can take a chip, and hooks to a computer with a USB cord.78s has a compass. Thanks KB for the info on the chip!We are actually talking about three GPS units in increasing order of expense, 78, 78s, 78sc.The 78 being the cheapest. Tide and current info is really a plus as well. I try and look for something, get lost in the thing, then realize I am in the wrong sub menu! But it seems to function well other than that. It is great paired with Garmin HomePort on my computer but on the water I wish it had a touch screen.Īlso the sub menus get confusing a lot. I thought it was more expensive than just getting the 78sc but that is just my recollection (I messed up ordering). I also have the 78s and then upgraded by adding the chart chip so I basically have a 78sc. I use my GPS equipped iPad all the time and have no cellular plan activated.Runswithbeer and I will be using the new iPad mini as our main nav in the EC. Works fine without the cellular, just might take longer if you have traveled far since the last time you used the GPS. Other than ' assisting' the GPS with the initial startup and giving it a clue where you are to speed up locating you. The iPads with built in CELLULAR all have true multichannel GPS chips in them and the cellular has nothing to do with the GPS. There is much confusion about 'assisted GPS' and GPSA. Now I know what chip I need to get for the EC! ![]() For fishing brushpiles when the boat is barely moving along, the S model is better for finding my brushpile waypoints.This is a good thread. I've found myself walking in a big circle for a few moments until the GPS can tell which way is what.However, IN FACT I find the S model is LESS reliable than the regular, non-compass model!One friend found himself paddling upstream because his unit lost its calibration.For paddling, I won't have a S model. If it is moving, it knows what way is north.So if you are standing still and don't have a S model, the GPS can't tell you which way is which. ![]() I have a Map76 and a Map76s, The difference being the sensors (S), ie the compass.You don't need the compass feature if the gps is moving. I'm still in the dark ages with the 76 models. Are the compass and barometer worth $149? Are there other features I'm missing that would help justify the cost difference?Are there other handheld GPSs I should be looking at instead of these? Durability and price are primary concerns. ![]() My last GPS had the compass so I don't know how much different the functionality would be without it. Seems the main feature differences are the compass and barometer. West Marine currently has the Garmin GPSMAP 78 on sale for $199 and the Garmin GPSMAP 78SC on sale for $349. ![]()
