Have an ECHOMAP Ultra with GT30-TM and GT8HW-IH Bundle.
When I get on pad (even at slow speeds, barely on pad) I lose bottom traditional sonar depth. It is almost like side and down view transducer on the jackplate is being used instead of the shoot thru transducer that they epoxied mounted in the bilge.
I see there is a Y-Cable that combines the two transducers, and is hooked up to Garmin unit and transducers.
This is all brand new stuff, and I am new to garmin.
Also will the older hotmaps micro cards work in this, i am used to Lowrance. and Lowrance would just bring the mapping up automatically.
Sorry for the questions..fellas ...love these Garmins. I also have Livescope and a two Ultra 106's mounted on the bow. One of them is networked.
