Garmin homeport charts5/6/2023 ![]() 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. (I'm primarily interested in data for Cayuga and Seneca Lakes in New York's Finger Lakes, which have full coverage for depth contours and navaids when I look at them directly from the device.) Rather, the Maps menu has entries only for the City Navigator product and for the Global Map, but not the pre-installed Bluechart product.West Marine currently has the Garmin GPSMAP 78 on sale for $199 and the Garmin GPSMAP 78SC on sale for $349. However, when my device is connected to my Mac via USB, Basecamp does not show me any of the marine data, which means that I can't establish new waypoints (or define routes, etc.) on the water. I also bought a 32GB micro-SD card and the City Navigator North America NT product on a CD, and have successfully gotten that map registered, on my Mac, and loaded on the micro-SD card in the Montana. ![]() I recently bought a Montana 600 Marine Bundle, which includes the Bluechart G2 US charts preinstalled in the device's main memory. Hi - if this question has already been addressed in an older thread, I'd appreciate a pointer to it I didn't see a thread title which looked promising. ![]()
