Minelab Manticore Update Today (oct. 18th. 2022)

The latency will depend on the bitrate they send the audio, seeing it's not some device playing music and needing fantastic audio they'll be able to use lower quality audio without it being detrimental and use a much lower latency. 

We don't need deep bass or any such things that someone playing music through speakers might.  LC3 also compresses the audio on the fly sending less data through the air meaning lower latency. 

LC3 scales from 345kbps right down to 160kbps. SBC, Bluetooth Classic’s mandatory codec, ranges from 345kbps to 240kbps—ut it takes a substantial hit to audio quality as a result. aptX Adaptive runs between 279 and 420kbps, while LDAC ranges from 330 to 990kbps. LC3 is by far the most compact Bluetooth codec used in consumer audio to date. But what effect does that have on audio quality?

Part of the Manticores delay of release will be it's processor, it's basically not even released in any great quantities yet.

I doubt we'll be getting our Mandymoores before Christmas, they must have just wanted to slow the sales of the Deus 2 and Legend by announcing the Muncheroo

PHRUNT you type faster then i think, was going to post this.     Somewhere in the info PHRUNT added i found this Quote.  LC3Plus will boast a latency time of around 5ms, much quicker than SBC's 100ms.   Latency may vary by device?  What ever it's good news.  With all the test graphs i saw in the FCC report I'm sure someone will distill it into dirtynesse for lugs like me.

Are these the same? https://www.mouser.com/c/semiconductors/?q=nRF5340&m=Nordic Semiconductor

yup, they have them in stock $17 each for the Manticore processor.

And just like that, I’m on the list.  Thanks Gerry. ?

I actually wouldn't mind an hour meter.  I won't miss it either, though.

But a clock...  No.  Detecting time is like fishing time, or hunting time.  No clocks.

An hour meter.  You mean like running hours?  My truck shows how many running hours?  That is kind of interesting concept but then those of us who hunt many hours and then want to sell our old detector for the new model Manticore, we'd have to swing it backwards for many hours to get the hour meter to show "low miles" meaning we get more $$$.

We could have a contest to see who hits the 1st 1000 hours on their Manticore and what all did they dig?

Is kind of interesting thought though.

That could be a good thing are a bad . Like you being you spend lots of time on one you may have to pay us to take it off your hand. The warranty is not in years anymore. It will have a pace meter so every time you swing it the meter clicks. Then after so many clicks your warranty is out.

 Gerry in 6 months I’ll let you pay me to take that Manticore off your hands. I’ll let you down easy. We’ll discuss what’s easy then.

 PS I’m just all heart ❤️

The contest idea would make a good promotion for your shop or even Minelab themselves. Kind of like what Garrett does in their Searcher magazine.

Pretty robust BT chip, geesh with Zigbee we could network our Manticores together and w/NFC we could use them to buy lunch ?
