Having built my share of coils in the day and knowing what i know about the black art ......epoxy shrinkage has always been a royal pain.....this problem has been around for a long time I have seen how some manufacturers deal with it ......usually it involves a process of having the ability to retune the coil.....meaning you open it up and manually set it back on the money ....the trick is to take it a little further just a hair and as it shrinks over time it becomes more true instead of less true....there are different types of epoxy some better than others .....
The fact that Whites has pushed the envelope with the Spectra is a GOOD thing ......I remember a certain manufacturer came out with a Bisexual coil ..
.HeeeHHAEEAAee.. No just kidding that gave them fits and still can be a problem to this day......Coils are the heart beat of any detector this.... IS where all Data must pass........Do You Take proper care of a coil that will Rx at 15 with TX Boost turned on...... Do you leave them in a car parked and locked up out in the sun that Acts like a blast furnace to all electronic component's..... do you store your gear in a cool dark place......My 950 and D2 and 5.3 all smoke ....and walk the dog.....these are precision coils.....they need to be treated as such not ax's to cut down pine trees and wild brush....If they go out of tune eventually Or the harmonics Drift .... will I get PO'D ....
..... No I will be HAPPY.... to go to my local Dealer and cherry Pick the best coil in his Shop and Pay cash to make him happy and me happy ........With any great undertaking or Laudable Goal.....one must persevere.....The money is in the ground ....know Your gear and take good care of it ...It will pay at least Ten fold! to the persistent hunter..... Treat her sweet and buy her a new dress once in awhile.......AND she will take you for the ride of your Life!!!!
Happy Trails
