internal vs external GPS

7 posts in this topic

I had the Lowrance 332i last year and had problems with the GPS. Skeels replaced the unit and it worked better. Now I am thinking about getting a different one for the new boat and start fresh. That way I know how old

everything is.

I am thinking about the 7" external mount GPS I think it is the LMX-27 or something. It is about $250 more than the 5" internal but I saved that buying the trolling motor and other stuff from the dealer.

Do you guys like the external gps?

I have heard that they fixed the 560 or whatever number the 5" is but you never know.

Which way should I go?

Where do you install the puck? My new boat is a full windshield. Some say to mount it at the far end of the boat on the "gunrail" Others say on the on the console.

We are going to mount our puck on teh "gunrail" toward the end of the boat. Im not worried about it getting hit by anthing so thats where it will go when this snow goes and I can get the boat out of storage.

I heard of many problems with the 334iGPS, but have heard the 522iGPS works well. I didn't want to mess with it, so I got the 520 with the external puck. One good thing about the external is that you can link it to another unit in the boat if you ever wish to get one, the iGPS is not NMEA 2000 compatible as far as sending the iGPS info is concerned. The lcx27 will be a nice unit, but I couldn't bring myself to spend an extra $400, they go for $999.00. I got my 520C for $560 on that big auction website, which is around $130 less than retail including taxes.

I just bought last year's 332 model with the external gps, you guys hear of any problems with that? The 550 screen looked only slightly brighter, didn't notice many other differences.

From what I have heard the external GPS on that model has been fine. You should enjoy that unit.

You absolutely cannot go wrong with the external GPS antennae - and as was stated before - you can hook up to 7 units to one antennae, including VHF radios for position locking and any other gizmo that could stand to perform better with a GPS coordinate. That internal antennae stuff though slick is just frought with inherrant problems which are obvious when you think about the type/strength of the signal that the antennae has to receive.

      Has anyone tried out the polar bird hub houses? The floor looks like a neat concept I wonder how well it works. Looking for a small 2 man hub so I don't have to drag my huge heavy 6 man thermal hub when I go alone.

      I don't care if dnr checks me multiple times a day or I have to prove that I am not doing anything wrong. That is how they catch the guys who are doing stuff wrong. I am always legal so What do I care I have been checked what like 5-6 times in my life so far even if every time they were a bad_boy ( they were not ) who cares I have to deal with them 10-15 mins out of my day? Think about how many pricks they have to deal with every day.
