After using this app on lakes I have fished for 50 years, I find the lake depths are not accurate. One lake with a known 50' deep hole only shows the hole being 30' deep. On the other side of the spectrum, another lake that has a max depth of 12' shows a 28' hole that doesn't exist. I waste enough time finding structure as it is. I don't need an app sending me to stucture that's not there.
