I hunt with both Tesoros AND Fishers.
I can't tell you how much fun each kind is to use and hunt with...in different ways.
I have always stated that hunting with a Tesoro that has no screen has benefits that will last a lifetime if and when you learn what hunting by sound using aural clues and manipulating the disc knob and using other techniques really teaches you how to hunt using only sound.
No matter what some believe these things are way beyond just "beep and dig" machines and can help you become a better hunter in the future no matter what you decide is your favorite type of tool...even the many great ones that have screens.
However when you are brand spanking new you need to learn the basics.
It isn't hard and even though some might have some frustration learning these things, digging empty holes, telling false signals from real and so on, this phase usually doesn't last long and we all go through it because it is a natural progression in this hobby.
Knowing what I know now I really believe that learning these basics is way more easier and a much faster process if you first start out using a unit with a screen.
The sounds are still important when using screen units but you have the extra information of the screen data that can help in this learning process.
The smart ones and most successful hunters in this hobby know that all info you see on the screen and hear in your headphones are just indicators and the real skill comes in taking it all in and taking educated guesses about what the coil is really scanning and what your detector is trying to tell you about that target....this is called learning the language and all detectors have a language.
Believing anything any detector tells you on the screen or in the audio clues 100% is never recommended, the only way to know what you are truly scanning is to dig it and hold it in your hot little hand, but that is the real fun about doing this hobbby...getting better and better at making those educated guesses before you dig and finding out you are right after you dig it.
Being surprised is also a fantastic part of the hobby too, by the way, dig up a pull tab and find gold instead is one of the best things that can happen to you, but this is a rare thing and mostly we must learn to tell the good but more mundane type of targets like coins from trash...and there is way more trash out there than good targets as you will see.
A unit with a screen and very helpful and informative VDI numbers can help you out more than you realize right now with all of this and learning those basics in a more efficient way.
I used an F2 for years and did well, the F22 is a new generation unit which I would love to experience and would be my recommendation to use as your first and to learn on.
It probably won't be your last, most of us upgrade eventually and add more to our arsenals along with other accessories like different coils, but you will know way more about this hobby, the tools we use and yourself before you even need to think about purchasing your next one.
I also believe that any hunter that doesn't have at least a Compadre in their arsenal is crazy because that is a surprisingly productive, efficient and fun tool to stand behind but the Fisher should be able to find enough coins to get you one fairly quickly if you still want a Tesoro and many of us use both kinds...I am not the only one.
Your first detector is an important one and never an easy choice when you are new without all the information that veterans have but you are doing it the right way by asking for advice and weighing your options.
Soon enough you will have something in your hands and will begin this wonderful hobby that might end up to be a lifelong passion.
Choose wisely and then don't look back and vow to learn your tools as best as you possibly can and you can be nothing but successful if you do.
