one of the mapping companies has an upgrading system that upgrades the depths as you go over them. you send them your updated depths and they then upgrade your card with everyone elses using the same system. thats something that might be useful your way. the map in the lowrance is almost useless for me but the navonics has me charting out more fishy water. even has the actual sand rock tree overlay to look for sand rock breaks along the coast where the stripers hang out, you can even see some underwater structure highlighting those places with the satelite picture shotsnolaegghead said:@fishlessman
I plan on updating the maps. Also would like to get the satellite overlay - a buddy of mine who pretty much only bass fishes (not my bag) figured out how to build the satellite maps using some software and google maps.
The depth info would be useful, but that stuff can change after a tropical storm. But something is better than nothing. Most of the areas I fish are 2-4' deep. Lake Pontchartrain is about 11' deep, but there are channels cut out, and I noticed a hole in front the the industrial canal in the lake that was 90' - I've actually fished that hole (didn't think it was that deep) for trout in the winter.
Tides around here are no more than a couple feet. Although you have to watch out if you're fishing flats around the intercoastal canal - I've seen boats in three feet of water tip over when that water goes to 6" after a container ship rolls by.
