In this Blog I’ll try to show the difference in the Navionic’s Hot Maps Premium and Platinum map cards and the Lake Master 3.0 map card. First off I’ll tell you that I have had to personally buy all three of these cards and I do not get any cards from either company. Price points on the cards are pretty close with the Navionic’s Platinum running around $199.99, the Premium at $149.99 and the Lake Master cost at $129.99.
One thing you need to understand is that the Lake Master cards are designed to work only in the Humminbird unit and not in the Lowrance units. Garmin and Ray Marine use their own mapping programs.
Both cards come with the SD card micro chip holder with the micro chip included. So no matter which unit you have they will work in either the full size SD card or the micro chip slots. These screen shots are from my Humminbird Onix 10ci SI unit. Also please note that the cursor was very close to the same location as I could get them for these screen shots.
Looking at the first card the Navionic’s Hot Maps Premium you will see that there is a lot of vacant blue areas on the map. This means that no one has taken the time to record the lake bottom and upload it to Navionic’s for update downloads. You can record the lake data and create an account with Navionic’s and upload the data to them and a day or so later you can download the updates and then it will show the contour lines for the area you did the recording on. If you will notice on the Navionic’s maps there will be contour lines that all of a sudden just stop. These are where the user recorded the sonar log and uploaded only to that spot and no further.
The map card screen shot above is the Navionic’s Platinum card and the brown area in the photo above is the original creek channel in this part of the lake. The white area is a feeder or ditch that is located on the flat. The closer the lines are together the steeper and faster the depth changes. The circular areas indicate either a high spot on the lake floor or a deeper depression on the lake bottom. The small dotted lines represent an old field road that ran on the flats before the lake was impounded. You might notice that there is some 3D highlighting on some areas of the creek channel and high spots. This is one of the features with the Platinum cards.
In the above screen shot is from the Navionic’s Premium map card. You can tell by looking at the light tan colored portion which is the land around the lake that there is no Google Earth overlay data. This to me is useless data that was not necessary at least for what I use the cards for. The colors are a lot lighter on the Premium card versus the darker colors on the Platinum cards.
Now let’s look at the Lake Master 3.0 map card. As you can see from the screen shot below there is a lot more contour lines which represent more of the lake bottom detail with this map. Looking at the map below there is very little areas in these snap shots that does not have the contour lines.
So wrapping up this Blog I would have to say that the Lake Master 3.0 card has a lot more lake data than either of the Navionic’s map cards.
I hope this will help you decide which map card is best for your fishing use.
