What is the advantage of a “wireless detector”?

[FORUM XP]

The disappearance of the traditional cable linking the coil to the control box (and the disappearance of the control box itself) has two immediate advantages: first, an obvious reduction in weight and bulk, no more problems with storage or folding up the stem, nor with broken or snagged cables in the woods… and second, a gain in signal acquisition quality, as the signals no longer need to be conveyed via a wire link but are digitised and analysed closer to the source by the ultra-miniature electronic circuit housed in the coil.
