Garrett Seahunter MK 2 coil durability? No proper covers?!? Plz tell me your experiences.

I have one of these detectors on its way to me. My only concern it that the only coil cover I see is for the 10 x 14" and seems like it m's solid design would be a problem, heavy drag with seaweed & sand. I know how to solve the flopping issues of a large coil though. I'll have both coils and hate running unprotected. Why Garrett doesn't off a form fitting cover seems absurd. I know about bedliner spray, marine epoxy and possibly some kind of wrap as protective options. Running the coil naked and avoiding the obvious rocks around jetties seems like what I may end up doing. This detector will be used only in salt water and I have expireince with pulse detectors. But not this Garrett. The control head /unit is a robust design but the coils concern me. If you use bedliner spray it has to non metallic, what brand?
Sea Hunter users - please tell me what you have learned. If you care to post up pics of what you've applied for protectant that would be sweet.
Thanks!

I've had and used my Seahunter for over6 years. Used the8" coil all that time until this year, I got a 10x14" coil for it this year. I will say the 8" still works and looks great they are very well built coils and machines. Just keep an eye on the bottom of your coil and if it ever starts to wear down, just get some rubberized undercoating and spray on it. You will love the Seahunter.

Thank you BootyHunter, your feedback is important to me. I know you are a successful water hunter, your general comments re the SH MK2 matter as well. I've had a PI Pro since about 2000 and know the quirks of a PI. The Garrett design of the control head is robust and looking at the coils I kept wondering why they were run "naked". When you get some time on your 10x14" I would like to know your impressions. I plan on using a longer coil bolt to accommodate sandwiching a rubber washer up against the outer coil ears with an outer nylon washer contacting rubber one & the bolt & nut on each ear. This combats big coil flip / flop in the surf by allowing torquing with hurting the "ears". It's worked great and I thought I'd share that.
Even though I don't post up much any more this is where I come for constructive info.

Thank you for the kind comments! The Garrett coils are made of a tough material and I guess that's why they didn't include covers. The great thing about no cover for these is not having to deal with sand getting trapped between the coil and cover. That was always a problem with my Excal. I like your idea for the coil washers, I may do that myself. Unfortunately I don't live near the salt water so my use is limited with the Seahunter. I've used it some in my freshwater sites but it has no real advantage over my freshwater machines in freshwater. So someone that's units the surf regularly may be a better source on the coil durability, but in my use and my impression of the coils I think they will be very durable. Good luck with your new machine!
 
I have a seahunter mk2 and have put many hours on it at the beach.The bottom of the coil seems to be very durable and only has light surface sratches on it.
I made a cover myself for a different machine that is light and durable out of a washing up bowl.Just buy a bowl and use the base of the bowl for your cover.Aĺl you have to do is place the coil on the base of the bowl and draw round it.Cut the circle out of the bowl,drill some holes around the edge of the plastic circle and cable tie it to the coil.This makes a very light cover that is durable and does'nt collect loads of sand.
 
Thanks guys. I've been looking at Plasticoat Spray on Bedliner that dries hard and the reports are good. 3M rubberized undercoat has been used by some and I do have that but want to either fashion my own "cover" or try the plasticote stuff first. Both are non metallic of course. My deep gold finds are dependant on a reliable PI because our New England beaches are mineralized, so all I find are new drops these days. My Whites PI has issues, the Garrett will arrive at my doorstep Monday 9/12 and I'm hitting the CT shore Tuesday. Maybe Cape Cod later in the week. I'm full of plans :detecting:!
Anyway I want to illustrate my method for keeping my coil from unwanted flop and tilt. There's enough friction so it is easy to adjust and holds the angle. First 2 pics are my Excalibur. The inner diameter of the rubber and nylon washers matches the coil bolt. For each application. The white nylon bolt doesn't show well in the Minelab pic.

Below is my whites DF coil, I used a nylon spacer with the 3/8" nylon hardware.

I do the same for my turf detectors if needed. I got away from loop supports when I discovered one wearing on the top of a coil housing.

I have had mine for about 10 years and it is still in good shape (No cover) and working as designed. Granted I only use it when I am diving now but before I started diving I used it for wading/beach hunting
