I’m actually planning on ordering a splasher prop this week. I actually have to avoid the guide boats due to not having a splasher or thumper yet. They have 2-3 boats close together running splashers and every fish under them lol. I’ve seen fish leave my graph and the group of guides start catching lol! Im def a believer.
I believe you can build your own thumper, the splasher is commercially driven.
