My previous boat had Lowrance electronics so didn't have choice but use Navionics. New boat I just bought has Hummingbird so need input from you HB guys. Which you like and why.

I use both, one company may do a certain lake better than the other. Depends on the lakes you fish. But using both you have it all covered

Use both. I went with Lakemaster last time, and some lakes it is not what I expected it to be. Im about to pull the trigger on a Navionics card to supplement it. I also didn't read over the lake list, and when I got to Broken Bow last week, it didn't have it on there. I was glad I still had a Lowrance unit with Insight still on the boat.

What they've said. Both

I just got a navionics to go with my lake master. I like both. I miss not having the shallow water warning and marking depths on lake master, while running navionics. The navionics give me more detail BUT I found lots of places on the lake weren't covered by navionics that were by lake master. It was much faster reading the lake master on the move due to being able to shade my shallow water and the depth that I wanted to fish at. Wish someone would come out with a card that combined the features of both.

I use both. You'll find things on Navionics that you can't see on Lakemaster, and you'll find things on Lakemaster that you can't see on Navionics. The Lakemaster depth highlight and water level offset features are priceless and once you've used them you'll never want to fish without it.

I have a question on this subject. I recently bought Navionics chip for my duel Lowrance 7's.
Systems are linked, but I can only view chip info on primary graph. Do I need 2 chips or is it operator error?

It depends on which 7 you have and the software versions. HDS Gen2 with the software update could, but Gen1 couldn't. Don't think the Elites can either.

+1. I use both as well.

If a possibility using both is not a bad option, if you don't have to why limit yourself to one tool. If owning both is not an option I would look at the mapping available for each at the main bodies of water you fish and make your decision from there. I cannot speak for Lakemaster, but you can view all of the latest mapping for Navionics at Navionics.com.

I have used both now and lake master is my choice

They're Elites.
Thanks for the info.

Both

I have lakemaster. I have run into occasions where the contours weren't exactly dead on, but IMO its a small price to pay to have the shallow water highlight, depth highlight, and water level offset.

Those are especially helpful when fishing new lakes.

Also one glance at the depth finder and potential points, humps, and channel swings just jump right out at you.

My buddy doesn't have lakemaster and I constantly have to zoom in on his maps to read contours and try to decide if it is a hump, a deep hole, or what.

I may eventually purchase a navionics card to compliment my lakemaster card, but I will not go without lakemaster.
