Thanks all,i was leaning toward the Furuno,but the Northstar looked very good,and a little less money.

My fishing is always in deep water.It's all great lakes fishing,and for a good part of the year, we're in 300 to 500 feet.
Price is a little bit of an issue,but naturally so is performance.I figure i can spend around $1,200 to $1,500 for the sonar and Gps.

I'll be selling my other boat with the electronics,so i'll have to go new on the Tsunami.I was thinking about the FCV620 Furuno sonar,and the 492 Garmin gps.
I also thought about a combo unit,but don't like the fact that if one go's,your without both during the service work.
