Several times this summer I’m running through narrow channels using my chart 
plotter and although I am visibly in the center of the channel, and my plotter 
shows I’m in the center, my wife’s android phone with Navionics shows us on 
land.  That happened 3 times in different locations.  My friend was on the boat 
earlier in the summer and his iPhone/Navionics identified the same problem, 
different location.  My plotter always seemed to be correct, while the 
Navionics on the phones doesn’t give me the confidence.  I’m in a rocky area 
and 50ft variation can be the difference between a hole in the bottom or not.  
I’m sure the variation between devices was 100-200ft.  I use the Navionics as a 
backup at best. 

 

Thanks,

I have Navionics on both of my android phones and on my chart plotters. I have 
found here in mexico that the charts on the plotter aren't as accurate as on 
the androids. You would think that for $250 for the plotter Navionics charts 
they would be more accurate than the $21 phone charts. 

Just voicing my displeasure in Navionics. Which BTW is owned by Garmin.
