NCtoad -- sent you a PM.
Hotrod65 -- the reason for the WM08 is that some folks really like the current, corded headphones they are using for other detectors, BUT still like the idea of being "untethered" from the machine. SO, they would like to use their wired headphones that they are used to, but make them "wireless" by plugging them into the WM08 and being untethered from the machine.
This is how most of us land hunters running the CTX use our headphones -- standard corded metal-detecting headphones (like SunRay Pro Golds, or Gray Ghosts, or Killer Bees, or whatever), plugged into the CTX's WM10 module. Thus, a wireless connection from the CTX to the WM10, but a wired connection from the WM10 to the headphones. Then, we can simply clip the WM10 to our shirt, or put it in a pocket, and we are then not "tethered" to the detector itself.
So, for folks who have interest in using their favorite heaphones with the Equinox, the WM08 allows that...BUT...the WM08 has a 1/8" headphone jack, NOT a 1/4" jack -- and thus is not compatible with most detector heaphones. So, an adapter is needed -- thus the 1/8" to 1/4" adapters I mentioned above. BUT -- as one final complicating factor, not just ANY 1/8" to 1/4" adapter will work. Reason being, Minelab is using the same proprietary screw-in 1/8" jack on the WM08 as they do on the control box itself. Now, you can use a "regular" 1/8" plug-in connector IF -- IF the connector is small enough to fit inside the screw-in connector. SOME jacks are too large to fit in. The ones I highlighted above all "fit" inside the screw-in connector on the WM08 (or the control box). NO, they obviously don't "screw in," but they are small enough to fit inside the connector, allowing you to use the adapter, and thus, whatever pair of heaphones you desire.
A bit confusing, but the whole problem stems from three things...
1. Minelab chose NOT to use a standard 1/4" jack on the WM08, but instead chose a 1/8" jack...
2. Minelab chose NOT to use even a standard 1/8" jack, but instead used the same waterproof screw-in jack as is used on the control box (DESPITE the WM08 being non-waterproof)...
3. Minelab does NOT have the adapter (1/8" proprietary screw-in jack to standard 1/4" jack) available yet. They WILL have this adapter availabe in the future, but it, along with all the other accessories, is not available yet thus forcing people to have to "improvise."
