How To Add BLUETOOTH Headphones To Any Metal Detector
Hey folks…In a previous article I described a way to set up any metal detector with wireless headphones using an FM transmitter and a small FM radio. I’ve researched a little more and 
discovered another way to add wireless headphones to any metal detector – this time with bluetooth. I need to preface this by saying I’ve never tried this, but it deffinitely seems feasible and would likely work better than the FM method.
Some web browsing has revealed several models of bluetooth transmitters that plug into a headphone jack in the same manner the FM transmitter would in my prior article. Some models include the IOGear Bluetooth Wireless Audio Transmitter and Sony Bluetooth Transmitter and Adapter. I’ve linked to both on Amazon. Be sure to research these and any other transmitters. One of the reviews for the Sony adapter mentions a lag time, so this could really come into play when detecting.
Once you have the transmitter, then all you need is a bluetooth headset or headphones. Tons are available online.
Again, I’ve never tried this but it does seem like a wireless option for those of you that want to sever the cord!
What do you think? Would this kind of bluetooth headphone set-up work with metal detecting?
Wireless headphones are going to become a player in treasure hunting very soon! White’s Spectra V3 already has a pair. Really good and informative article.
I’ve actually done a lot of investigation on wireless for metal detectors, and, well, there’s a bit of a problem with bluetooth and FM.
For bluetooth, the problem seems to be one of a significant delay. OK for audio, but not combining audio/video, which detecting certainly is.
For FM, the problem is RF interference from radio stations and electrical noise.
HOWEVER, I think I’m on to a solution, which is actually the best of both worlds, and am scouting for the needed parts. 2.4gHz headphones/earbuds seem to offer a really good alternative. While earbud setup isn’t exactly cheap (about $120 at Radio Shack), there are plently of relatively inexpensive 2.4gHz headphones out there. All we’d need is an inexpensive transmitter that’s either rechargeable or takes rechargeable batteries.
In the next week or so, I plan on trying to adapt the $120 solution from RS.
