Are the new G2 models that have SI, built in to the unit, or is it the transducer? I have a G2 HELIX 9 on the boat with SI, and want to use my ice unit in the boat as another unit, but don’t want to buy it if I network the 2 together ,I’ve heard it will use SI off the transducer running my 9. If it is built in is it a big help finding fish when you’re hole hopping?
