I also decided to perforate my solid coil covers on my Sea Hunter Mark 2 build to let any water and sand run off or through the coil covers since the coil covers for the Garrett Mono coils are solid. Hopefully by doing this It will prevent any issues that a coil cover might cause on these style coils in a beach surf hunting application. I would hate to have to remove the covers as they prevent abrasive wear to the bottom of the coils.
Note,
The yellow zip ties where added to sea the coils easier under water. Also they were added because the 8” coil cover is for the Garrett ATX Mono coil and fits just a hair loose. ( Note, Garrett don’t make a coil cover for the 8” Sea Hunters Mono coil) The Sea Hunters 8” Mono coil needs the zip ties to keep the ATX 8“ coil cover in place.
