Mr. Monte, I just picked up a like new Whites IDX-Pro and was trying to find out if you know if I might be able to have the dectector modified to be so 'modified' as by Bill Crabtree (Mr. Bill). I’m new to metal detecting but it seems this is a useful add. Just don’t know where to start, or if Mr. Bill is even available (or do you?) to perform such motificationson my IDX-Pro. I can’t find much info on Whites website. Any idea how long ago this model was produced by Whites? Any info you can provide will be greatly appreciated. I live on the TEXAS coast and have many beaches available to look for sunken ships, coins, old ranch houses and towns, etc.
Last question, it there a brand and model you might suggest for wet beach and shallow salt water metal detecting for old silver and fold coins?
Thanks, John
Welcome to the Forum...not speaking for Monte but here are my thoughts on the IDX Pro........And the Mr. Bill's modifications
...For all we know, your IDX Pro might be properly adjusted, just flip the trigger switch to All-Metal mode and search for clean metal free spot on the ground. Only then can you do a proper ground balance, one adjusted it does not need further adjustments...But when changing search coils, make adjustments as needed.
...This is an old thread, and doubt that Monte is still following this thread. Just my 2¢ thrown in on the conversation. The IDX Pro really can be used without the Mr. Bill mods. I know what you are thinking but have some patience with me as I have adjusted the Ground Balance on the same detector using the little Ground Balance pot under the "Made in America" sticker. It is easy if you understand how to adjust a "Threshold" based All-Metal mode ground balance system !
....Here is how I do the Ground Balance on a stock IDX Pro without the modifications. Let's assume that the "Threshold" pot located inside the case(VR4) is adjusted just right by the factory and is producing a nice smooth and pleasantly low audible hum when using the trigger pulled All-Metal Mode. The trigger switch can also be flipped forward as a temporary locked position. All the while doing this outdoors away from any electrical interference and placing the IDX in All Metal Mode. Run your detector coil close and parallel to the ground listening to the Threshold hum. Search for some clean ground that contains 'no metals', this is accomplished when you have no audible rises in the Threshold during some "short" sweeps of the coil. Once you have found a quiet area without any metal targets. This is where you peal back the Made In America flag sticker and see a hole in the case... inside the hole you can see a miniature adjustment pot. With some good light you can see it quite well and all it takes for adjustment is a small homemade slotted screwdriver made out of some scrap plastic.
...Over the clean piece of ground you just found in all-metal mode...again... using this same mode, keeping the coil parallel and using an up and down motion...pump the coil up and down rapidly from about 6 inches above ground, down to about 1 inch above the ground. Listen carefully to what the Threshold is doing, is it going silent as coil gets closer to the ground?, if so use your homemade plastic screwdriver and turn the little GB adjusting screw clockwise...and if the opposite happens when the Threshold gets louder as coil approaches the ground use your screwdriver to turn adjustment pot counterclockwise, MAKE ALL ADJUSTMENTS IN SMALL INCREMENTS...about the thickness of a US nickel or 1/64 inch. Don't be afraid to experiment with it as you can always go back to how it was set if adjustments were made in small increments.
...If adjusted just so...there should be a slight rise in the threshold as coil is pumped toward the ground and all coin zones on the meter should airtest correctly. This may procedure may sound complicated BUT would still have to bee done even with the Mr. Bill's mods. Just saying that you nay not be able to get the modification done and this would be your only option. I know of two guys that in the past that did the mods, but not sure they do this anymore.
...One more thing, the IDX Pro...once correctly adjusted,,rarely needs repeat adjustment. As the famous Ron Popeil of Ronco fame says "Set it and Forget it"
