I bought a new Skeeter 2190 this fall and have a Helix 12 mega di at the console. At the time, I didnt know much about these units. Salesman told me I can add side imaging at a later date with a different transducer. I trusted him. Now Im looking at side imaging and cant find any info on it.
Can I buy a new transducer and use my existing unit, or do I need to buy a new Helix12 with SI??
