Lakemaster vs. Navonics zoom feature

12 posts in this topic

With Lakemaster you can zoom in closer but why is that such a big thing when Navonics has higher definition. HTB

I had tried the 06 hotmaps and on a lake with 1' contours you could not see between the lines so to speak. Very hard to tell what contour line you were on. 3' or 5' lakes was not a problem but the 1' confused.gif

the zoom range on any chip is determined by the unit reading the chip. Currently Humminbird units (Navionics only) zoom in the closest < 15 feet (which is commonly inside 1' contours). Lowrance units usually zoom in at a much further distance usually 0.08 miles or 400'. You will find that zooming in to far does not do you much good as you lose perspective on the map quickly. I commonly zoom in to 100-250 feet and find that much better then < 50 '

It's nothing to do with the units it's the chip Lakemaster Zooms in much better then Navionics and as stated above it realy makes a difference.

LM zooms in closer than Nav. I'm not sure what you mean when you say Nav has higher definiton. You get better definition from LM because you can zoom in closer. You would get better definition on a gps with higher pixel count but that is determined by the gps, not by the map chip you're using.

That depends on how close you're zoomed in, and how steep the break is. The steeper the break, the closer the contour lines, the harder to see between them.

Not true, it is the map chip that determines how close you can zoom in, not the gps

That was my point, When you are on those breaks and zoomed as far as the chip will allow you cannot see between the lines and unfortunately these are the lakes that are the most accurate sooo what good is it? I have heard Navionics added 2 more zoom levels in 07 but have not seen this for myself.

Yeah, a while back FMer Jeff@Navionics said that either the '07 chip would allow for closer zoom or that a software update from Lowrance was coming for the iFinder units which would allow for it, I can't remember which he said, or if either one is true... I haven't yet picked up the '07 Navionics chip, so I'm left to wonder: Can you still only zoom in to 1/8 nm on the new one with the latest software update installed? With the '06 Navionics chip and Lowrance's software ver 1.1 installed on my ExpeditionC, it's frustrating when wanting to zoom in on that spot-on-a-spot, and I find myself thinking of swapping the LakeMaster chip back into the unit for the day -- even though it doesn't have that lake's contour lines -- just so I can more accurately follow a previous trail or be more precise in going to a previously marked waypoint.

So the way I understand it now is that zooming in closer allows you to see where your at between the 1' contour lines. HTB

I upgraded to the expedition from explorer. I have not been able to obtain a WAAS signal from my expedition yet? It locks in quickly and has epe in low 20's on 3d fix, just doesn't go to WAAS. I do have the box checked that says enable WAAS. Am I missing something? Do others out there signal into WAAS? How low do you get epe? Thanks

I don't get WAAS very often on my H2Oc. Every once-in-a-while it will find a WAAS signal, though. My EPE is most often in the 30-40 foot range.

While over on Lil-Bay-Denoc a couple of weeks ago one evening I was able to get the full Waas with an EPE of 13 feet with my H2O.

Hitthebricks- When you are using a high definition chip with 1' contours (even 3' on occasion), all the lines can blur together. If you can zoom in a little farther, you can see the structure. At times it can make a huge difference. I also find that navionics maps load slower when zooming in or out

      that's the spot I would go also. I tried there once this year, not much luck, but I did mark many fish.

      I have a couple of those covers.  Not sure what they are good for.

      For all you pan fish lovers, check out this beautiful pumpkin seed I found guarding the bed while I was out bass fishing. Couldn't help but get some video of this beaut! Enjoy!

      My live well has an adjustable shut off valve in side for filling and running fresh water. If I don't turn it down to a tickle when I have fish in it, it will over flow into the boat once full because the pump is pumping faster then the overflow can keep up.  Not sure if you have one of them in yours?  I've even had a few big eyes flipping around in there hit the valve open more.

      I believe minnows are a class of fish that remain small throughout their lives. They are part of the food chain and because of their small size we take advantage of their position in the ecosystem and use them for bait. There are exceptions of course but, as an example, for the most part adult golden shiners will typically grow to about 3" - 5" long. Adult fathead minnows will be 2" - 3" long typically.

      If the hoses or hose connections are not leaking check : Live well intake connection, make sure that it is screwed on tight into the transom and that it is sealing. Could be live well splash over also if you are in rough water, but probably not with your type of leak. It may still be leaking rivets as they may not leak unless you put a lot of water inside of the boat. It does sound like you have a bad connection in one of your live well connections! Cliff
