Sonar option for Garmin 7212

[MICHAEL ERBGUTH]

I'm looking for a budget option to add sonar to my Garmin 7212 ? I need a IN HULL mount transducer as I don't want to drill the hull. I'm just looking for a good depth and large structure readings. Don't need to find fish just bottom profile for diving. Depths from 0 to 300 feet ???

Any thoughts or options ???

Thank you.

No in hull will give you anything like what you are asking for, there just isn't such a thing. You need to drill a hole ...

You would need a GSD24 at a minimum and a supported transducer like one of these: https://www.garmin.com/en-US/c/mari...terTransducerCompatibility_SounderBoxes=gsd24

I am not sure what you mean by "good depth and large structure readings" the structure reading capability can be quite costly and may not be available for your 7212. Unless you mean straight color line blip.
