Non-Lowrance transducers in the Outback scupper

I am thinking on getting a new FF, possibly handing my Hook 4x off to my wife for her Sport.

Let's just say I am underwhelmed with the Lowrance menus, and would like to consider other brands.

I do want to use the scupper mount, so I am looking for reports from folks that have installed a different brand, without modifications, in the scupper.

I am specifically wanting GPS, but that shouldn't have anything to do with the transducer per se, other than perhaps compatibility with certain models.

I suppose I could be talked into modest modifications, given the details.

I use the Raymarine Dragonfly 7Pro with Berley Pro transducer mount
