We just went through this 3 weeks ago...search for "Hey Minelab".
Short answer is this:
Last update was last year...when they added Chinese language. woohoo.....
Last REAL update was 2012...when they added to actual functionality.
I'm of two minds on this.
One is that since I own the detector(s), I'd REALLY like to have seen a few specific things improved and added. That's the promise of a firmware update-able machine..."Future Proofing".
But I feel that since they've already got my money, Codan/Minelab can't make any more from me with free updates...so it's off to other, newer projects.
(Besides, I'm not in the market for a gold detector, so I'm not even on the radar.)
And that obvious attitude of theirs continues to cause a LOT of ill will throughout the detectorist world.
But my other 'mindset' is this:
It works really well now. Well enough for me to own two.
Why would I not buy something simply because it hasn't been updated...if it already does what I want?
Whether there have been any updates or even if the detector couldn't be updated, ever...it works really well now!
When was the last time you got an update for your eTrac or F75?
Ummm.....never.
Does that prevent you from owning/using a couple of fine detectors?
Of course not.
So I completely agree with you on one level, but think your logic is flawed on another.
Maybe Minelab would have been better off to do like Fisher did on the initial F75 DST teething problems?
Just keep sending the early units back until they get the firmware right...then stick a fork in it, and call it 'done'...no (major) updates, ever.
No expectations. No disappointments.
I don't know the answer...but if do know if Minelab seriously wants to work on another update to the CTX, I'll be happy to help them improve it!
