This is the down imaging version of this graph...there is just a cd HD. So it came with the DI transducer, which is not bad. Can I replace with just the XNT 9 20 transducer thats 2d sonar only vs replacing it with the XNT 9 DI transducer that originally came with it.

Looking for a very budget 2d sonar and the price of the transducer is half the cost.

thanks
