Brian........I was just ready to trash the pink bunny rabbit batteries
thinking that I should have stuck with the gold top variety instead!
Several other listers and listerines have mentioned the recycling time
question and I will check this out. You are the first person to mention the
AM radio station tuning trick which I will check out......in fact I have
not heard of this before. I have a feeling that my flash gun is just fine
but that the operator is a bit of a dunce. Having numerous consecutive
shots which show such a diversity makes me think that I should take an 099
course in flash gun use. I have never developed any expertise ...... or in
fact any great interest either ......... in flash use and don't want to
blame my tools at this early stage of my enquiry.
