basstrackerman Posted August 13, 2024 Author Share Posted August 13, 2024 I use it daily and I've had zero problems I have not noticed any falsing of any sort it acts exactly the same as it did when it was 5 oz heavier. I'm sure I have no warranty but I think I only have a year left of warranty anyway and it's not like I don't have other coils cuz I do have the 9-in coil and the 15-in coil so now it's probably one of the lightest 11-in coils on the market in the round version that is a little over 14 oz. 4 1 Link to comment https://www.detectorprospector.com/topic/26429-m11-coil-mod-cut-out-struts-light-and-fast-underwater/page/2/#findComment-279209 Share on other sites More sharing options...
Tony Posted August 14, 2024 Share Posted August 14, 2024 Is the Dremel the "go to" tool for this job.....cutting wheel first followed by the "sanding" style wheel ? Also, do you need a couple shots of bourbon to steady the hands before surgery 🤔 5 Link to comment https://www.detectorprospector.com/topic/26429-m11-coil-mod-cut-out-struts-light-and-fast-underwater/page/2/#findComment-279232 Share on other sites More sharing options...
Hunterjunk Posted August 14, 2024 Share Posted August 14, 2024 Will certainly be doing this to mine when the warranty period draws to a close . Also I note the new 18" Coiltek has an abundance of spokes/ribs . Looks like the removal of the short ones front and rear would not be a problem . 1 Link to comment https://www.detectorprospector.com/topic/26429-m11-coil-mod-cut-out-struts-light-and-fast-underwater/page/2/#findComment-279259 Share on other sites More sharing options...
Tony Posted August 15, 2024 Share Posted August 15, 2024 I have emailed Coiltek asking about the "need" for all of those coil ribs. I mean Minelab designed the M9 without them. I suspect they have a coil die that is used across different detector models....and they are expensive to re-design. The Manticore 18" coil is identical to the Equinox 18" coil. I'm guessing Coiltek felt the need to be comfortably further in size than the M15.

Tony Posted August 15, 2024 Share Posted August 15, 2024 So Coiltek have said the ribs are to minimise flex from side to side......and any mods will kill off the warranty.

It's for minimizing falsing from coil knock due to Manticore extra power.. I'm surprise when M15 came out with no extra ribs.. Maybe they were looking in the wrong place , carbon shaft ? 😃 2 1 Link to comment https://www.detectorprospector.com/topic/26429-m11-coil-mod-cut-out-struts-light-and-fast-underwater/page/2/#findComment-279296 Share on other sites More sharing options...

bklein Posted August 15, 2024 Share Posted August 15, 2024 Do you have to seal off any exposed openings with JBWeld or the like after the cuts?

Rick N. MI Posted August 15, 2024 Share Posted August 15, 2024 No, it's just the plastic material there. Link to comment https://www.detectorprospector.com/topic/26429-m11-coil-mod-cut-out-struts-light-and-fast-underwater/page/2/#findComment-279304 Share on other sites More sharing options...
