Mike,
You will be good with the mapping that is in the unit already. The only thing the mapping doesn't have is vision and that is worthless anyway. The card reader door is magnetic so you shouldn't have a problem and it takes a regular micro sd card for storing and transferring data. You can record the sonar, take screen shots and store the live bottom mapping as well.

To get touch screen you would have to take the next step up to the xsv series. They do it all but at a hefty price. Unless you absolutely have to have touch screen or need radar I would stay with the 94 SV Chirp. Give me a call when you get ready to order and I will see what I can do on finding the best price. The one you quoted was including the GT51 TM. That is a flagship ducer but the GT 52 is a very good, if not better a ducer than the 51 in the depths you will most likely spend most of your time. It's also shorter and may be a better fit allowing you to mount it at the bottom center of the hull where it works best. It's also less expensive than the 51 and would reduce the overall price of your package.
