I bought this product then added the English Channel sailing map from the Garmin site and I've used the map for various sailing trips in the Solent. I've had no problems with getting a GPS signal and the map has been very accurate. (Lots of other maps are available e.g. for walking.) One or two items on the 78S have been tricky to find in the menu system. I asked for help at the Garmin stand at the boat show and it took three people before getting an answer. Basically even though the screen only shows one option, which is selected by pressing Enter, on some screens pressing Menu can give more options. Simple, but not that obvious when using the 78S. All in all, it's an expensive package but worth the money for piloting in unknown locations and if you don't want to be stuck at the navigation table unaware of what's happening up top.
Garmin regards this as a marine device, presumably because of its water resistance and the fact it floats. It is difficult to load maps on to it (but possible) and the support lby Garmin I found truly terrible (the chat was useless and it took five calls to the voice lines with endless waiting to get the issues resolved, with some agents being v helpful nd some downright uninterested.). So that is more about garmin support but as the product is a garmin product that is a key component. Does it work? Yes. Would I buy another garmin product? I doubt it to be candid. That is based on my experience with the Fenix 5, this 78s and my motorcycle navigator. Look hard elsewhere.
It's got all the functionality needed for sailing, and while resolution/screen definition isn't up to iPad standard, it really is hyper rugged and will take any amount of water, rain, bashing etc. One issue I have had is the unit switching itself off straight after start up, but solved it by performing a master reset: no idea why, so it loses a star. Charts are expensive too.
The product came super fast which was great, no issues there! I found the world map to be very vague. It’s not meant for Canadian waters. I did not purchase the Canadian chip map for Canadian lakes/waters so it might have been more in depth, but also the chip needs to be updated every year so I couldn’t justify the price of an additional $200+. I’m certain buyers living in the US have awesome reviews on this item. It just wasn’t for me and my needs and area.
I purchased this marine gps unit on July 4th 2012 and used it on a trip from Canary Wharf to Harwich and back on an old coal fired steam tug later on that month. I cannot praise it's performance enough being totally accurate at all times and even more useful with the micro SD card containing the Dover to Amsterdam and England Southeast marine chart which I purchased direct from Garmin. It took some time to work through the full instruction manual(downloaded from Garmin)and I had to phone Garmin a couple of times for help which was politely and patiently given. This unit gave great piece of mind during our trip and I would thoroughly recommend it.
Built-in obsolescence (if you let the batteries die on your old one, it quits finding satellites and you have to buy a new one, even though probably all it needs is a software reinstall). Nosebleed-expensive SD map cards EXTREMELY fragile, like a flake of varnish, with the 76Cx cover designed to close on the chip & snap it in half. Miniscule screen, a loose back cover that you will need to keep track of for the rest of its life, super-vague map descriptions (and no support) misleading you into buying the wrong map(s), every aspect monetized to the max (e.g. designed so no holder but Garmin's will fit it). Buying this thing was a miserable experience.
Ich habe das Gerät ausgepackt und für die erste Hausrunde mit der Karte versehen, die während der ersten 200 m tadellos mitgelaufen ist. Auch die Genauigkeit war während des Laufens nicht zu beanstanden. Als ich sodann stand, war eine Abweichung von etwa 10-15 Metern festzustellen. Als ich dann 2 Minuten später weiter lief, blieb die Karte einfach stehen, jedoch funktionierte die Anzeige der aktuellen Geschwindigkeit noch. Dies ist völlig inakzeptabel, weshalb ich das Gerät wieder zurückgesandt habe. Wen es interessiert: die Menüführung ist gegenüber dem 60 CSx überarbeitet, aber erschließt sich von selbst. Die Anzeige ist mit der des 60 CSx vergleichbar, jedoch scrollt die Karte viel schneller mit, ohne dass der Prozessor überfordert ist. Allerdings erscheint regelmäßig am Rand ein weißer Balken, der nach zwei, drei Zehntelsekunden wieder mit Kartendarstellung gefüllt wird. Insoweit eine klare Verbesserung gegenüber dem früheren Prozessor, jedoch kann das Gerät mit dem deutlich schnelleren Oregon 600 nicht mithalten.
