Exactly. Quite possibly one of the single biggest flaws in Lowrance sonar technology. I've been using the app on my phone to navigate my local reservoir for a couple of years now, and it's phenomenal. Being able to adjust not only makes naivgation simpler, but when I'm targeting say... rock piles in 13'-18' of water, I can literally plan out my day before ever making it to the ramp by marking all the new hotspots because the water dropped 5' this week. The problem is, not only can I not update the water level on my Elite 9 Ti the same way I do with this app... but that's one of the PRIMARY REASONS I BOUGHT IT... it was supposed to have all the same navionics features built in. It doesn't. Beyond that... there's no reason this couldn't be automated, especially for large public waters. They KNOW what full pool elevation is. They have the GPS data to tell you what your current elevation is when on the water. Anyone ever hear of subtraction? "Benchmark Elevation - Current Elevation = 50' drop... Would you like your chart to adjust?" Yes/No. This aint' rocket science. Truly disappointed in my unit right now, and this is the key reason why. With my phone, I can run my lake day or night without worrying about a rock pile that wasn't there last week. But staring down at my phone when I've got a $1,000 sonar unit in my dash is asinine.
I heard Lowrance and Navionics are compatible along with a handful of other units, meaning you can import contour maps and I assume other features to your Lowrance. Garmin bought navionics but yet they’re not compatible. Guess who has a new Garmin unit?? Ended up buying a nice large tablet installing the navionics app and subscribing. I think it’s an awesome product, useful in terms of navigation and fishing.
It depends on drought or flood levels for that area and time observed. Maybe some conservation or government authority might have these numbers or some indicator in your local body of water that measures the levels or check your local charts or other sources. You can also look at a body of land and see if the Navionics app approximates what you are seeing. If not then just rise or lower the water level until it matches or approximates real life assuming you don't have tides in that area like a lake.
There has to be a more scientific way to determine how much to adjust. You are guessing. Navionics should tell us what the level is based on there default mode of the map. The maps have to be based on a certain water elevation when they are installed, thus you can get the current level from the corps of engineer or whoever and adjust your Navionics water level more precisely.
Mike Hogan I’ve found that as soon as you get on the water look at your finder and confirm it reads the same as the navionics map.. if not just adjust accordingly
All charts depths are based off a lake's normal pool. If at normal pool, you're in 10' of water, then the lake drops 12' you'd be sitting on dry land. The best way is to Google the current lake level, then adjust your water offset accordingly.
I have literally been trying to do this for years on my iPhone and it still doesn't work. I make the adjustments on the phone but they only change the colors on my phone- never the depths themselves. Don't feel bad, the actual Navionics video is just as inadequate. Frankly, I think Navionics is an awful app. I could write a book about all the things I hate about it. Here's one other than the present discussion. 1) I bump things on this app all the time and open things I don't want opened. A simple back button would be awesome but no, I have to figure out the specific sequence to close what I've just opened accidentally, often by pushing multiple buttons- an that's after I've spent lots of time trying to figure out how to do that. Sometimes I'll spend 10-15 minutes just trying to close what I've accidentally opened. Even a simple RETURN button or default would be helpful here. Like most of today's technology, it's very complex and needs VERY DETAILED INSTRUCTIONS on how to use it. In your video: 1) Do I need that specific body of water to be pulled up on my phone? 2) How do I adjust that one body of water and not all of them at the same time? 3) Do I need a chip in my phone or fishfinder for it to work? It doesn't work and like I said, I've waited years trying to get an answer. Fortunately I kayak fish so it's unlikely I damage a whole lot when I hit something.
Josh, how do you cha
Now lake level on Humminbird or Lowrance unit, with navionics chip installed??
Will this work with C map?
how do you adjust water level on the lowrance hds

How do you know how far to adjust the water level?
It depends on drought or flood levels for that area and time observed. Maybe some conservation or government authority might have these numbers or some indicator in your local body of water that measures the levels or check your local charts or other sources. You can also look at a body of land and see if the Navionics app approximates what you are seeing.

Awesome video!

Not clear to me what you did and why. What does it mean to adjust water level?
All charts depths are based off a lake's normal pool. If at normal pool, you're in 10' of water, then the lake drops 12' you'd be sitting on dry land. The best way is to Google the current lake level, then adjust your water offset accordingly.

along with navionics +
It sucks but you can get this on a phone/tablet for 21 dollars a year but you have to pay hundreds a year to get it on your fish finder.
