question for 6" coiltek digger coil owners only...

[mike slaw4all]

i recently bit the bullet and purchased the 6" digger coil to try out in some of the many high trash areas around town.
my question is, it came from the factory with a piece of heavy black tape that wraps around the edge of the seam of the coil and coil cover, what is the tape for?
if the tape comes off does the cover fall off? the specs. say it's 100% waterproof but i'm doubting that tape is going to last very long underwater, so you can see why i'm curious.
on the plus side, given the same ground conditions, the ID numbers for coins are exactly the same as the 10.5" 7.5khz coil. also, it's VERY sensitive to SMALL pieces of copper/silver, i dug up a tiny copper disk shape that was 1/32" thick by 1/4" diameter at 3" deep, the sound in the headphones was pinging like a surface find. after digging, i finally found it with the pinpointer and couldn't believe that tiny thing made so much noise under this coil. i thought it was gonna be another small piece of gawdy sterling silver jewelry barely under the surface like the 10.5 would have sounded.
ok, back to the subject, whats up with the damn tape?

thanks, mike.

Hello........the tape around the edge of the coil is factory installed. There is a coil cover on the coil and this is how it is held in place. The tape also seals the seam where the coil cover meets the coil to prevent dirt from getting under the coil cover. I found it also acts as a protector when you are swinging the coil around rocky areas.....saves a few nicks. The tape has nothing to do with the waterproofing of the coil.

thanks for the response,

i haven't ever taken the tape off yet so i didn't know if thats what held on the cover or if it sort of snapped on like the others.
funny you mentioned keeping dirt out, i just took the cover off my 10.5 for the first time a few days ago and there was easily 2 ounces of dirt in it. maybe enough to affect the ground balance, who knows.

thanks again, mike.

Hi Mike .... Thanks for posting as I had the same question. I just got mine yesterday. Installed it to 705 and was out a bit with it in the PM. Mine came with the tape also. As Hunt2 mentioned presume it to be a factory install. Keep us posted.

Coil covers are nice protectors. However, I haven't used them in years!. I spray my coils with 2-3 good coats of the spray type rubber, (like truck undercoating). It can be bought most anywhere. In the end I carefully tape off everything but the edges of the coil. The edges get the same treatment. Been using this process for a long time and have never had any coil problem. I have always used Rustoleum but, on the next coil I purchase, I'm going to try that, "flex-seal" product they advertise on the TV. It seems to spray a nice heavy coat. But, I will call the company first, and make sure the product has NO metal in it. Seems that about 15 years ago, (or so) some of these rubber spray products had metal in them and it caused all kinds of hate and discontent with detector guys. I know Rustoleum doesn't have metal. As an aside, after my own impromptu testing, I could not register any kind of sensitivity or depth loss. Sure beats the heck out of removing the cover and cleaning out dirt...Or forgetting to clean it out!!

I believe that the waterproof issue between a sealed and not sealed coil was the flexible connector on the top where the wire comes out. The coil protector and the tape has nothing to do with being waterproof or not.
