Yes, I did this a few years back. Product from “Transducer Shield and saver”. Stainless steel, spring loaded , kicks up on impact.
Pros:
Seems to be kicking up on impact, no damage
works well at trolling speed. I have an in hull Tx for speed, so no problem.
Cons:
Think I overtightened when installed, developed cracks in face of transducer, repaired
Not cheap but neither are transducers
I have the top part of the original Lowrance bracket, yours if you want it. PM me.
