Lowrance Point 1 GPS antenna

I posted this on another site and figured it might be of some use here. My new point one came today so I pulled the boat outside and plugged it up. Since I already had a LGC 4000 I thought I'd see if there were any differences in how many satellites they would pick up. There are several trees around where I was parked and my shop was close too. I sat the Point 1 right next the 4000 when testing. I repeated the test three times and the results were the same. Your mileage may vary.

The internal antenna on my Gen 1 HDS 8 was first.
9 satellites, EPE of 29.5-31.2'.

LGC 4000
10 satellites, EPE of 21.6-23.5'.

Point 1
12 satellites, EPE 12.8-13.4'.

so, what do they cost?

Retail is $199, I gave $160 shipped for mine.

how many satellites do you get on a big open lake?

Haven't had it out, I just got it yesterday. I think 12 is the most it can pick up though.

I've seen EPE's as low as 7ft. but I would say 9ft. is a good average.

wonder what I'm getting now with regular internal GPS

and where would I plug it in , hds 9 touch

Black round connector (NMEA2000) network. But, of course, you have to add stuff to make the netwwork work. Endless gouging.

Lots of information here.

Lowrance Help Topics, Networking Diagrams, Troubleshooting

With the software fix, the Point-1 works great.

so I can't plug it straight in ?

Unless you already have a NEMA network, no.

Justin, doesn't the Point-1 come with the network cables & "T"? I thought it did.

Don, mine came with one T and the cable. If you don't have a NEMA network you will need a power node, another T and cable for each unit in addition to the T and cable that comes with it and the terminator ends. I think that's all.

would this do it?
i don't see the end pieces
Lowrance NMEA 2000 Starter Kit - N2K-EXP-RD-2

That would do it almost. You need a switch and another T (which usually comes with the puck).

I got my network stuff from Brian @BBG.

The ends are there, "terminators", you'd need a switch and I'd put a fuse on it. A T and cable come with the antenna.

it has been suggested that the point 1 antenna would smooth out my hds9 screen, do you consider this to be a possibility?

I don't honestly know.

Technically it could (if it works properly) on the map page. The xternal gps includes a digital magnetic compass and has a 10 Hz refresh rate. This is twice the map page refresh rate capability as the internal gps, Also if the mag comp is active , it should refresh more accurately with respect to direction of travel and speed vs refresh of last known gps location data.. I don't know what speed the mag compass kicks in, but I have used digital mag compasses on robots and they have about a 2 degree accuracy, 2 degrees IMO is fairly accurate when you are 10-20 foot away from a waypoint (brush pile).

Brett...I think something is awry in your new Touch....

I don't own 1 ...but I'm sure your issue would have come up before in the forums if someone else had experienced the jerky scrolling you describe...

Maybe you should contact the dealer you bought it from....(if it's Brian or David ...either one would know if this jerky scrolling is normal or not)...
