Fisher F75 SE on deep silver dime

F75large-popUpeditHi everyone…here is the next in my ongoing series of metal detector tests on the same deep silver dime.  Up to bat is the Fisher F75 SE.  So far, this one knocks it out of the park as “best” at giving me a “DIG ME!” signal on the dime.  Like I’ve said before though, lots of variables to consider from ground moisture to undetectable RF noise.

A look back at Detector Stuff Metal Detecting interviews

avatar_42014 is here and the start of a new year can be a time to reminisce. As I’m building up some new content, I thought it may be good to also remind folks of some of the great stuff we’ve had here over the years.  I’ve been fascinated with the people behind the scenes that make our hobby fun by creating new and amazing metal detecting equipment!  Below are links to some of our past interviews with industry leaders….

Fisher F70 Review

fisherf70

“The Heat!”

To put it bluntly, the Fisher F70 is THE HEAT! As a proud and happy owner of an F75, I caught myself thinking…”I bet the F70 will be a scaled down F75”. In some ways, I was right. A few less features than the F75, (and I LOVE the F75 trigger!…it should be illegal to build a metal detector without a trigger!) However, Fisher retained the most useful functions and made them very accessible to the user. There’s also a little something extra under the hood… more depth than the F75! Yep, you read that right! In my soil, coil-for-coil, the F70 is slightly deeper than the F75.

Speaking of coil-for-coil, if you already have an F75 you can swap coils back and forth. The new elliptical concentric coil for the F70 is great! Excellent design, construction and balance. However, slap the big F75 11” DD coil on the F70 and hang on! I’m talking SERIOUS depth here! Select the “slow” option in areas that will allow it (lengthens the sampling time on the target…if I understand it correctly) and you will be getting way, way down in the ground! (I picture moles, grubs and earthworms packing their bags and fleeing the radio waves in utter terror!) However, due to the lengthened response time, the odds of masking due to nearby trash are increased…but I love having the option to pick which way I want to hunt, depending upon site conditions.

Fisher F4 Review

f4largerI’ve always heard “The older you get, the faster time passes.” Now that I’m in my mid 40’s I’ve found that statement to be all too true. However, there are exceptions to this rule…. Christmas, payday and waiting for a metal detector to arrive in the mail! I’m the first to admit, I become very “kid like” when I have a new machine on the way to my house. My wife is very “understanding” of this affliction of mine, only succumbing to the occasional “eye roll” when I constantly babble on about treasure hunting, old sites, coins and metal detectors.

1 Detector Stuff Interviews FT-Fisher Engineers, David Johnson and John Gardiner

From left to right: Mark Krieger, New Product Development Engineer; John Gardiner, Electronics Engineer; David Johnson (kneeling), Chief Engineer; Jorge Anton Saad, Electronics Engineer

Introduction:

First of all, I want to thank Tom Walsh, Mike Scott, Tricia Richardson, Dave Johnson and John Gardiner for their help in arranging this interview. I think it’s a fair statement that First Texas – Fisher is one of the most exciting metal detector companies on the planet right now, and as such, has piqued the interest of the hobby detecting world in a way that hasn’t been seen for quite a while.

I had the idea for this interview months ago, before I had started this web site. There was quite a buzz in the forums when rumors started of a new Dave Johnson design coming from First Texas under the Teknetics moniker. After the subsequent release and success of the T-2, the hobby community was set on fire with excitement over the prospects of “things to come”. Another wave of excitement hit when it was learned First Texas had acquired Fisher, and that wave turned into a tsunami with the release of the F-75. Mr. Johnson was quick to point out that the T-2 and F-75 were team efforts, not solo projects, and that Engineer John Gardiner was key to the success of both machines.

The purpose of this interview is to give the fans of metal detecting a “behind the scenes” glimpse of the engineers who designed the T-2, F-75 and F-4. There is an unusual “connection” people in this hobby have with their metal detectors. Over time, they seem to take on a personality of their own, becoming an extension of the owner/user. Because of this “personal” connection, most view the responsible engineers with a sense of awe and mystery. I feel that “getting to know” the Engineers will help people appreciate and applaud the outstanding efforts of these geniuses behind the scenes.

All questions below are for both Mr. Johnson and Mr. Gardiner, unless otherwise designated.

Question 1:

DS: What got you interested in engineering metal detectors?
