Hey Shooter,
It is going great. Learning the F75 is not really difficult, of course, I still have a LOT to learn. I have found it rather simple, after getting the real machine to play with. Reading the manual before getting the machine was a little daunting, but, after having it in hand, everything started to make sense. I have only been on one real outing and only for a couple of hours. I used the default setting for the first hour and then switched to AM, set Disc to 15, Sens to 90 and did a manual GB. I used the 3 tones and with just a few tries, it became quite easy to rule out tabs and flattened cans. TodayI got permission to hit a schoolyard , so, as soon as I have an opportunity, more 'practice' and [hopefully] productivity will be had. The first hunt was in a very trashy place and nothing of consequence was found.
Drop me an email [roland58 at suddenlink dot net] after you get yours and let me know what you think about it.........I'm betting you will love it!!!
