Thanks crappie limits I was hoping that someone would clarify that. I will probably get the hdsi transducer eventually but after my recent issue with the exchange program I want to try the compact transducer first and see what it's like. It's fun to look at the nice pictures on the pc but with glare and water spots on the screen while in use I would be a little annoyed that I wasn't able to see a vast difference while on the water.
