HDS -7 estimated positioning error

5 posts in this topic

When I look at the satellites it is locked into I noticed I can never get any better than in the upper 20's to mid 30's for the EPE reading. If I am understanding correctly if I mark a waypoint and come back to it later I could be off by as much as my positioning error was when I marked it. To get this more accurate would the LGC-4000 puck be worth it? Wondering what the puck would get the EPE down to.

Thats an excellent question. When I bought mine, a gentlemen recommended that I take it out and try the internal first. After trying this it seemed that the cursor was too far behind than I really liked it to be. I'm thinking about spending the extra $370.00 + and putting the 4000 puck on it. With my LMS 480 with a puck the reading was up to snuff.

Do I need to purchase the Lowrance N2K-EXP-RD-2 Network Starter Kit if I am adding the gps puck to my HDS-7? Or could I use the cable that is included with the puck?

You will need the starter kit also. Unfortunately you have to buy them seperate.

Where are you getting a price of $370+? We sell the LGC-4000 puck for $250. Lowrance Accessories At Pro Fishing Supply

You will need the network kit to use the GPS puck, but even with the kit you will be just a bit over $300.

I've toyed around with the idea of putting the LGC-4000 on my boat. From what I've heard and seen it does reduce the position error --- the 4000 puck updates something like 5 times faster than the other pucks or internal antennas --- after that its up to you to decide if 20 feet is worth it.

Position error does not tell the whole story. If you're going to worry about position error then you also need to watch the HDOP, it's on a scale of 1 to 10 and tells you if the current positioning and arrangement of the satellites is going to give you a more accurate or less accurate position. Lower number is better, high number is worse. If you have a 20-30 foot position error with a high HDOP then I wouldn't sweat it.

    • I used to sip cognac with a beer and I didn't even get in to whiskeys or bourbons until 8 or 10 years ago, so as a novice I started with the Canadian blends like Crown, Tangle Ridge and Pendleton and I'm more of a sipper using the old fashioned glasses.  I can't give recommendations on any of the really good brands, but if you ever see some of this... run screaming from the bar.  
    • Catfish is right up there with walleye, perch, trout, steelhead, salmon, flounder, grouper.....
    • What does it matter what Bernie Sanders had figured out considering the DNC blatantly rigged the primary against him? And then they tried with all their might to do it again and were exposed.   Face it, you party is fueled by people who are showing that they are the very ones they claim to be fighting against.    Immoral, intolerant, violent, judgemental and full of hate. 
    • hope to have my nills by next weekend to do some testing. 6 incher. putting it with a ryobi 600 pound torque drill with 4 amp batteries. sold the clam plate and auger. friend also use it with the milwaukee drill and same hang up issue. used an 8 inch k drill on bowstring last week with the milwaukee fuel.  opened holes nice and drilled nice. 
    • Trump totally destroyed by hundreds of thousands the numbers that were in attendance for the inaugurations of LBJ and Gerald Ford. Trump again wins. Just win, win, win, win, if not pretend you did.   He may just do the same thing to the country, so don't get to excited.
    • Just drove down from the Brainerd area. Lots of snow up there but going fast. Saw 4 young guys in a ditch south of there with not much snow and one sled with hood up smoking bad. Their still learning you need snow to cool your liquid sleds!
    • What a fun election cycle, first Trump dismantles the Republican party and may take them to even lower lows by winning. Then even more surprising is the Democrats totally imploding all on their own and losing to Trump in the process. No hollywood script can compete with this kind of crazyness, just happy to be alive to witness all of this mess and hope there is much much more to come. Something tells me I won't be disappointed, I am almost excited for the next one, 4 years ago I never would have thought that in my wildest dreams.
    • If this crazy weather keeps up a guy might have to go to the mountains to have enough snow to ride.
    • I purchased a 20v 986 Dewalt brushless and used it with my Nils 8" and could not believe how fast it cut. Very close to my Tanaka motor as far as speed. My plan is to use it with my 6" Nils but wanted to give it a good test and it passed with flying colors. 
    • Pretty sure Bernie had that figured out. After the primaries I voted for "not Trump" You guys haven't picked up that liberals are still going for not Trump, even if that means Mike Pence (who from a political position standpoint is worse for liberals).   Instead you have Trump, a man incapable of taking any form of criticism regardless of how irrelevant it is to anything. Why do I post the crowd sizes? Because Trump, in a speech given only to members of the CIA, thought it was important enough to mention, as well as to have a team of his own people there to applaud when he mentioned the size of the crowds.
