Seahunter MK 2 Coil durability? No proper coil covers? Experiences please chime in.

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!

The 10x14 would be good for dry sand, it would be tough to handle it in rough water, I hunt gulf shores and in to Florida and it gets brutal just to hunt in the water even with the 8" , marine epoxy would be just fine and doesn't cause any issues at all , GL&HH

Thanks Hank:thumbup: I appreciate the input. I just got back a couple of days ago from the beach and had the chance to water hunt with both coils. I had no problem with coil flip in the surf or deeper because I always replace the 3/8 coil hardware with my own setup that uses a longer bolt with added neoprene and nylon washers that keep the coil where I want it set. I have used a PI on theses mineralized New England beaches and the MK ran well. We just bought a place in Florida a couple miles from the gulf coast slightly north of Tampa for future snow birding after wifey retires.
After this maiden voyage of the MK 2 I decided to coat the coils. I have some marine epoxy but decided to go with 3M rubberized undercoat, contains no metal. Light coats and a long cure time adds durability. Reapplication if needed is easy and some of the desert scrubbers in oz report it isn't a bad choice. I also looked at Plasticoat bedliner spray but wasn't stocked locally. I'll see how this holds up.
Though no gold this trip I did get some very small jewelry and am pleased at how the MK2 runs. There are just places and times I want a PI over my other water units.

On another site it was recommended that you spray the coils with a product called Rhino Liner which is what they spray truck beds with.
Never used the product as you cannot buy it in the UK.

Thank you for the info. I will add it to my list. I'm looking to see how the 3M product holds up after after a long cure time. I expect to get to the ocean this week.
 
Just a thought.
On my Vibra probe 580 I use a product on the probe head which looks like putty but is a two part resin filler. It comes on a small clear cylinder about 3in tall all you do is cut off what you want and mix the inner core and the outer wearing rubber gloves and work it as required.
Sorry for being vague but I cannot find it at the moment.
On the Vibra probe it works for about twelve months.
 
Thanks JAN1, I think I grabbed some of that putty just incase among the epoxies I stocked for various repairs. It is the JB Water Weld. Seeing how I repaired a lower rod with JB plastic weld and it has held up great . The clevis portion just fell out of the lower of my Excalibur and the repair is stronger than stock.
 
Your welcome , MK is just a straight forward machine, continued success, HHHank
