Navionics or Lake Master

Fish N. Texas lakes only. It's for a Helix 10. I fish Twok most of the time. Looking for the best one to show humps, drop offs etc. Thanks in advance as usual. Y'all are greatly appreciated.

Lakemaster is better marked and easier to use if you have a Humminbird.

That's what I'm needing to know. Thank you

I like having both. My Lakemaster is better in some lakes, and Navionics is better in others. If I were to have just one, I would go Navionics.

Navionics is much more accurate for my home lake. Lake master is way off.

This^^^^^^

I have had both. Navionics gives me a better depth range and reads the trees better as far as a layout of the lake.

Guess I shoulda made a poll. Navionics seems to be ahead. Thanks guys.

Hands down Navionics. I have had both, and the Navionics is far more accurate on all lakes I have fished. For several years I ran both map programs on the same boat. I can take you to multiple points and humps on multiple lakes where the LakeMaster chip is way off. I hear that Lake Master is better on some lakes, but I have yet to fish a lake that would lead me to agree with that statement. Also, if you ever do any saltwater fishing the LakeMaster chip is completely worthless.

i prefer Navionics however there are inconsistencies on Lake Lewisville where I fish. I have an older chip though, and it's likely they have updated it since 2012 since I purchased it. So part of my complaints appear to be self inflicted since I haven't taken the time to update.

Navionics

Go check out the Navionics Webapp....that shows you all of the latest and greatest from Navionics for free, so before you spend a dime you can decide if they are right for you. With the Sonar Chart program Navionics is averaging around 20,000 updates per week. Now granted, those may not be all the lakes you fish, but it is a good example of why the free updates that come with the card are important to utilize.

Or if you may have an old card, whether it be a LakeMaster, Navionics or any other brand, you can save some cash and buy the updates card. This card is the same data just gives you a price break due to already buying another card.

I can update my old card to the latest and greatest? How?

Never have used Navionics. On Cedar Creek Lake there are many areas where Lake Master is way off. However, it is useful enough for me.

I swear by Navionics. Has saved me from running into a sandbar at night on a few occasions.

I have both. The highlighted red and green that you can adjust for shallow water and say a depth you wish to target on Lakemaster is nice and pretty, but Lakemaster is way off on depths on most of our lakes in north Texas. Navionics is spot on so far as I can tell. If I only had one it would be navionics.

IMO one of the most important features on your Helix 10 is Autochart. And it won't work with Navionics.

What card do you have now? If it is an old or premium card or another brand you can buy and updates card and use your existing card to activate. Once activated, you will have a brand new Nav+ card just at a discounted price for being a prior customer. If you have an older Platinum card, you can call Navionics, tell them you want to update an old Platinum card(which the new ones you can just do online but due to the old cards size 2GB it wont hold all of the data) they will send you a new platinum card with 1 year of updates for the same price as updating a new one online $99. Then from there on out you will just be able to plug it into your computer and update.
