This seems to be a frequent question as of late. I have read a ton of articles on this, and I am still on the fence of whether this is a good idea or not.
Some plates require screws or bolts, with holes in the hull, which to me defeats the purpose. I will give you that it allows for moving the transducer, or replacing, without more holes in the hull. But more pics I see posted, the cable holders are screwed into the hull as well ?!?
Luke, I have seen 2 styles, one completely holeless with epoxy only, the others have some kind of mounting hardware that require a hole in the hull. The epoxy ones I was most interested in, do have some issues, like with the epoxy letting loose, and if you ever need to remove it, good luck. I will say, everyone I know has gone to these boards, both styles, and I really have yet to see any issue with any of them personally.
I’m not sold this isn’t just sheep following sheep thing, and it doesn’t provide enough benefit to even worry about it.
