F2 battery rotation

[trueblue]

I just ordered an F2 and wanting to know if it drains the 2x9v 's evenly ....I owned a bounty hunter QD II in the past and it required that the batterys be rotated at about half strength to get the best use out of them as they drained un evenly ...is it the same on the F2 ?
cheers

Yep, it'll buy ya a little bit. Make sure to turn it off before you swap the batteries over.

I have found gold with mine and silver galore, a beast on coins and the info on that screen is extremely helpful, especially in trashy sites.
I can tell so much by solid numbers and even more by the jumpy ones.
The Fishers have a language like no others, and once you learn it the sky is the limit.
I still can't believe this is considered a 'Beginners Unit", and I am so glad it is in the arsenal because I wouldn't know what I would do without it.
Have fun!

I check my batteries from the F5 when I replaced them last week, one bat was at 7.4v and the other was at 8.2, F5 batt meter was at 8v. First time I've done this so I don't know if it is the machine draining them unevenly or the batteries themselves. I read the machine can run on one battery so the batteries should be parallel to each other, which suggest that they would drain evenly.

F5 totally different battery system from the F2/4. F5 batteries are wired-OR through rectifiers so if two batteries aren't equal, the machine runs off the battery with the higher voltage until it drops to the voltage of the weaker one at which point the machine begins to run off both.

Sounds like the lower voltage battery was a used one; or, if new, it was a dud.

And, if it was new and a dud, I'm betting that it was a Duracell. Used to be a good brand but they've really skidded downhill the last 2-3 years.
