I own a Lowrance i Finder Hunt c plus. Like yourself my wonderful wife told me to get whaterver I wanted as a brithday gift in January, I love her. I had a GPS on my Christmas list for 4 years,watching how they have changed in that time is really amazing. I use the lowrance alot just found it hard to leave the house without it for about a month. it has a pretty good base map allready on the unit. I had the green light on buget so I went with topo map software and it is great, even has some long driveways on it! I shopped around online got the package deal to my door for under $400. good luck but give the Lowrance a good look. oh yeah one other thing it runs on AA batteries and uses a SD card the same as my camera does. The recharge AA are always ready, no waiting while the unit sits and charges. check them out.
