I always go with latest revision. There is a reason they update firmware. I have had nothing but positive experience with each update. Last update was the best. I love 4khz for deep coins. Although I will say 5khz probably works just as well. I just didn't give it a lot of thought or use before the update.

Wondering how many has adapted to the 4khz vs 2.1.12 or even keeping it on 1.7.5?
Thanks
