Re: best coastal usa hand gps = garmin 78sc

I want a basic handheld for sailing in the northern part of Barnegat Bay NJ, but don't want to spend a lot. Just daysailing in my Precision 185 - a few hours a day, within a couple miles of the marina. I just don't want to run aground.
- Does the 'worldwide baseman' have depth information?
- Would I have to buy another chip for this basic info?

"I just don't want to run aground."
I would suggest paper charts and piloting. Forget the GPS and electronic charts, unless you are also willing to keep updating them as the bottom changes. Take a paper chart, draw a line at your comfort depth (you have the 3.5' keel?) then draw another line for every foot of tide and pick the areas to stay in, or out of, based on the time and tide.
Squinting at the tiny GPS and trying to be more exact, is likely to just get you stranded better as it distracts you with what appears to be more precise information, which really isn't.

Regarding paper charts, do you need a gps to tell where you are and correlate it with the paper chart? Do you have to rely on visual landmarks on the shore, buoy and can numbers, etc?

No, and no.

You don't need or must many things, but you need some way to correlate reality t the charts if you want to make use of them. A loud crunching sound followed by "We're on THESE rocks." can also work.

A GPS or piloting skills can also work. Doesn't matter which, whatever you prefer.

You could, but then you might as well have a chartplotter, and let the electronics do all the work.

That's called "piloting" or "coastal navigation." You should know how to do that, and "dead reckoning," at least.

GPS' are relatively complicated electronics. They fail. If you cannot navigate w/o one, you might find yourself at sea, someday.

(Pun intended.)

Re: best coastal usa hand gps = garmin 78sc

I want to use a marine handheld gps for basic daysailing in Barnegat Bay - along with detailed paper charts.
WestMarine has an older model, the Garmin 76Cx on sale for $149. Would that meet my needs enough? Without spending twice as much on the basic 78 model?

Yes, you also have to get the local charts for it, which adds to the price instead of just the basemap. Ask when you buy. It's a great unit. I love ours. Very easy to use, lots of features and the batteries will last a day or two, easy. We use rechargeables, and there's a software switch that lets you switch between alkaline and rechargeables.

Either works. A paper chart, a hand bearing compass, and some visual landmarks will help you determine your position. ( take 2 bearings about 45 degrees apart.)

If you simply study the chart and become familiar with the waters you will be fine. Running aground in Barnegat Bay is not the end of the world. Much of the bay is what I call Muck..( soft) it won't hurt you. Backing out, heeling the boat, kedging off, works well. The sand is mostly on the eastern side of the bay and you can use the above tactics or just get out and push...

I use MX Mariner. I don't have problems with it, and it serves me well.

Still, as many have mentioned, i use it as a backup. When things can get wet, or just a bit rough, Garmin 78 is in my hand.
