F5 questions????

[hihosilver]

Still pondering which of two dectectors to buy (please don't move this thread, it really is a fisher question)... I have a few questions for the F5 users out their:

1) Does manually adjusting the ground balance 10-20 points +/- make the F5 hotter on lower/higher conductors (like it apparently does on another machine close in price)?

2) If you were to run the F5 in the three or four tone mode with the Iron not completely discriminated out, do you get the same tone effect as the so called "Iron-audio" featured on another comparable machine of the same price range?

3) How well does the F5 handle emi interference compared to other Fisher models? I have been reading some posts that say it is better than most, and some that say not so good.

1. Ground balance settings will have an effect on target id accuracy and target sensitivity. However, the F5 is not like the one you are trying not to reference. The reason is the frequency in use and the gb spread. The F5 ground balance settings have more effect on low conductor targets as the ground balance is moved toward 0. There is not much to gain by offsetting the ground balance for high conductors as the design engineers have kept the ground range far enough away from the high target range so that you do not see the same affect on the other end of the scale.

2. No. That audio feature is unique to that "other one" you are comparing to.

3. The F5 has more controls available to handle EMI than most. The independant gain and threshold controls, plus the frequency shift, plus coil size/type options, plus the two stablization points (stationary and motion) allow for multiple EMI mitigation strategies for when you need it.

EMI is site specific. Some sites will be horrible, others not too bad, and some sites will be perfect. Two weeks later it can all change and the horrible site will be huntable, while what was a perfect site two weeks ago will be bad. The nature of the beast. You set up stable and hunt based upon the conditions of that day.

Good luck with your choice.
