Garrett MS-3 Z-Lynk Wireless Kit

Bought for the freedom and convenience of headphones that were not attached to the detector. I was initially disappointed in the performance. No complaints with the audio delay of 17milliseconds, but transmitted signals of detected targets was erratic. The signal would cut-out, then back in again in a most annoying manner. Had composed an email of complaint but delayed sending it until I had had more experience. Tried different mounting locations for the WT-1 on my Garrett GTX. Searched the internet for ideas, reread the instructions several times and decided that the crux of the matter was in properly "pairing" the headphones. Did this and found a world of difference. Now quite satisfied. Cannot give 5 stars as have never used any others to compare with.
