Well I just got back from sending my F-75 in for the updates and to be checked out. I talked to Felix yesterday and he assured me I would have it back in plenty of time for the DIV in a few weeks. I had noticed the machine not acting up to speed on my last few hunts. What I mean is, it would seem as if it wasn't GBed and would give false signals like how a machine does when it needs balanced. It wasn't acting erratic or motorboating numbers like it does around electrical interference. It "seemed" to be working okay but I noticed on some days when it balances fine, that I find a lot more goodies in my pouch but I don't have another F-75 to compare this one too. Hopefully they will run some tests on it and get her back in tip top shape for the DIV. I took her out yesterday for a going away hunt since I'll be out of a machine for a week or so. Got a few things anyway even though it was being a butthead for not wanting to balance.
