Bassin Butch, I understand the problems with the older units I had a Megellan that was difficult to operate. The unit I have you just hit the enter button and hold it down and it saves the way point right then. Then you can go back later and name it. This unit has pop-up windows that walk you through each step and tell you what each function does. I can't believe the difference there is from the old unit and the new. It is very simple to operate. Which is great when you on the water and go across something that you want to go back to and check out.

When you buy the MapCreate Topo USA 6.3 the package is suposed to come with the SD card reader and all the soft ware. The only thing I see so far is that you can only use 5 different cards after that it will not allow you to put stuff on different cards. The H20 uses up to a 512MB card and you can save and change info on it then down load that to the computer for each of the lakes that you visit. I cant imagin putting that much info in there that you would need a different cards (or more that 5 cards) since all the info is saved to you computer and you can make back up fills on CD's also. Then when you want to revisit that lake and go back to those same spots pop in the CD and save that to one of your registered cards and go fishing.
As you can see I'm pretty excited about this. I see a whole new world opening up to my fishing plans.
Here is another site that can help you alot too. He uses the high dollar gps and sonar units but assures me that it can be done with a hand held too.
http://www.hightechfishing.com/lowrancetips.html Pretty interesting reading there too. Also the Map Creat topo USA has some enhanced maps that you can down load for free, that show contor lines and all the submerged roads and river and creek channels. That will be a big plus to the software.
I will post more on this as I learn and even try to write a couple of things about it to put here as I go. Like I said I believe that this will help patterning fish in the differnt seasons that you can use over and over.
