Great video Gotau shows the issue really well

I am in my 70,s and can definitely hear the hissing in the ML100 when connected to the 6000 via bluetooth.Though  I have noticed that If I connect the headphones to my mobile phone there is no hissing.

This is a video of my 6k when I tested it at the Maryborough test site about 6 weeks ago. About 4 in the afternoon quite warm and no clouds. I think the threshold is fairly stable compared to yours and I did find  a 0.03 piece with it the following day. I do have the volume set to minimum.

I hate headphones and the internal speaker really isn’t all that desirable, so I “boosted” my audio with the Avantree collar speaker - I can still hear the significant changes in tone with it, even in a pretty noisy environment. So I saved my money for the larger coil instead.

Another vote here for the avantree. Normally have the volume of the 6000 low and the avantree at full. Works for me so far and you hardly notice they are there, i lift the collar of my shirt up. Very good battery life as well.

I spent around 20 mins retrieving this bit, lost it at least 3 times, put it down to bad procedure on my part but also think it maybe has something to do with the size of bits this thing (6K) is capable of detecting.

Very interesting read. Thank you for sharing

I did a significant amount of research into this and settled on this one.

14 hours battery life, decent well known brand and it has the Csr8685 chipset.  The latest version while many on the market still have the older Csr8650.

The receiver mode supports atpX HD not LL, so may not be suitable for some but I'm using it as a transmitter.

Of course like everything Bluetooth it's backwards compatible so will work with older chipsets like the atpX Low Latency Minelab use in their headphones, It's very simple to use which I found a must, I didn't want a bunch of options and input ports that I'd never use seeing it's just for a detector.  Simplicity and lack of "features" was a plus.

I intend to use it as a transmitter for my older style GPX 5000 to pair to the Minelab Bluetooth headphones that came with my Vanquish that I've never used, the same as the Nox ones my 800 came with which are also never used , along with a Bluetooth LL portable speaker as an alternative to the much slower ProSonic seeing I had to return mine and was left without an option other than seeking an aftermarket replacement.

I'll report on how it goes once it arrives.

I purchased one of these about 18 months ago but have only used it for watching tv with headphones on occasion so as not to disturb others. Sometimes I notice the lip sync to be a bit out but generally seems acceptable. It will connect to my EQX 800 as a receiver and the "+" symbol shows when it is connected. So I would presume it would be OK on a 6000.
