    The Bounty Hunter TK4 Tracker IV is easy to use and works great. The waterproof 8-inch coil lets me search in wet areas, and it’s tough enough for all kinds of terrain. The controls are simple, and the different modes help me find valuable items while ignoring junk.

    I’ve used it in parks, on beaches, and even on rocky trails, and it always works well. It’s lightweight, durable, and perfect for beginners or anyone looking for a reliable metal detector. Highly recommend!

    Purchased this product after losing my gold wedding band doing yard work in the small wooded area next to my house. So much brush and leaves that I knew a manual search would never allow me to find it. Figured this item would pay for itself if I was able to locate the lost gold ring. Setup was easy. Instructions were clear. Unit runs on 2 x 9V batteries. Within an hour (20 mins setup and 40 mins searching) I had retrieved my lost ring. This unit did everything I needed and we still can take this treasure hunting at the beach in the future. Great stuff! Also, unit is super lightweight which is also a plus.

    I have had little experience with metal detectors, except for having built one once about 40 years ago as a project I found in an electronics magazine. I still understand in principle how these devices work from that experience and from a general background in electronics. Basically a balanced circuit is produced in the two coils at the end of the unit. When the flux lines in the coils are changed by induced eddy currents (by passing near a metal object), a difference signal is generated from the unbalanced conditions which lets the operator know that something has changed in the field of the detector coil. BTW, this is why one must move the coil in order to induce a signal. A static coil does not experience any changes. Different metal groups produce different phase responses, which allow for some rough discrimination of the type of metal producing the response.

    My point is that these things can finicky as most anything that changes the reluctance of a tuned circuit will generate a difference signal. So the trick is to just generate a signal when an object of interest is passed over.

    All of that said, I am favorably impressed with the operation of this moderately priced unit. It is rugged. It is very stable. It is sensitive without being too sensitive so that too many false signals are generated. The notch filter function seems to work well. It does not seem to be much affected by soil mineralization (at least in my yard) or soil moisture levels.

    I purchased the unit to find nails in the yard. I had my roof replaced a couple of months ago and even though the crew did an excellent job and ran magnetic nail sweeps over and over the yard, I could still go out with a powerful hand held magnet mounted on a short wooden handle and find nails. After several weeks of this sporadic activity, I realized that if I were to have a shot at finding 99.9% of the extant nails, I would need a better way to detect them. Hence this detector.

    I use the detector in the non-discrimiating mode and have found nails that were obviously left over from when the house was built almost 20 years ago! For this purpose it has worked and worked well. I have even done a small amount of digging to get the long buried metal up and out of the yard for no other reason than I can locate it and then retrieve it.

    No treasure, so far.

    Learning to narrow down the source of a signal by making "X" sweeps takes a bit of practice. After only a few minutes, however, even a novice such as I can quickly get an idea of whether the object is on or under the surface and if it is iron/steel or not.

    The grand daughters, 6 going on 7, and 9 going on 14, have taken to this device in a big way.

    Let me explain.

    I salted two areas of my rather large yard with 1- $1 coin, 5 quarters, 5 dimes, five nickels, and five pennies each. These areas were well removed from one another. I made sure that the coins were not very visible, but otherwise were dropped randomly. When the grand daughters last came to visit, I asked them to help me find treasure in my yard. I produced two wadded up "treasure maps" and let them select which one they wanted. Then I showed them the metal detector and explained how it worked. I had a minute timer along with two baggies labeled with their names in my pocket. The timer was to keep the peace as each girl got ten minutes alternately. The baggies were to keep the loot separate and separated.

    I believe the 6.5 year old would still be out there looking, if we had not forced her to come in that evening. All in all the youngest found all but 6¢ but oddly enough, she ended up with 4¢ more than I had planted. You see, she found a dime that I had not put there! The older one came up 11¢ short and was most disappointed that her sister had found more than she! As a bonus, they did find 7 nails that I had not expected to find as these were in areas well removed from the perimeter of the house.

    I also had an opportunity to explain to the older one that this was an application of science, where she could use a device to sense things that she could not see, hear, or feel. This made an impression on her, I could tell.

    They want to come back and do this again!

    Suits me fine.

    So what does this have to do with a review of a purchase? This unit has worked well in not only my hands but in the little, inexperienced, and often clumsy hands of two children (after shortening the pole). It is light enough in weight that neither I nor the children had any difficulty using it. The smaller did have to use two hands, however.

    I am pleased with it in general, but I have yet to test it for unsalted "coin shooting" (I love that term), relic hunting, prospecting, or general treasure hunting as in finding objects of value say at a public beach, park, etc.

    I would recommend it as a good, affordable, general purpose metal detector, with the caveat that I have few benchmarks such as how a higher end unit would perform for comparison, such as a unit that worked by pulse induction, for example.

    This is my first metal detector (though I've used other people's before), so, to figure out what to buy, I read many product reviews on amazon and on metal detector websites. I main hope to find old coins. I came to the conclusion that I should buy this detector along with the Garrett Pro-Pointer.

    Considering this product's relatively low price, I thought it might have trouble finding anything, but this detector is very good at finding coins as well as trash. (Note that I use this detector in conjunction with the aforementioned Garrett Pro-Pointer, which speeds up the recovery speed perhaps 10x and is amazing to see/hear in action. You really need both, or the recovery process will be excruciatingly slow.) After a few days' practice, I am starting to be able to discern the size and depth of an object even before digging, which helps me decide whether to even bother digging. (I realize I may be passing up some treasure, but digging up lots of trash is so discouraging!). So, now I am pulling up mostly coins and trash that's the same size as a coin. I still haven't found anything the least bit rare, and I figure my hourly "wages" have averaged about 40 cents (from the coins I find), but it's fun, and I'm still hopeful I'll find something worth talking about some day.

    In practice, I generally leave the sensitivity setting all the way up, the mode set to TONE (which beeps nicely to indicate treasure and beeps harshly to indicate trash), and the discrimination level set to about half way. However, if I am in an area that has hardly any metal and am struggling to find anything, I set the mode to ALL, and turn the discriminator down all the way (because that maximizes the machine's overall sensitivity). Once I get a beep, I switch to TONE and 50% discrimination to get an idea of what's buried. Later, I try to remember to switch the settings back to maximize sensitivity. There are lots of ways to successfully use the controls. The worst thing to do is to not bother learning how they work because they are essential to your success.

    The length of the stem of the detector is adjustable (just like on exercise equipment), so I shorten it to the shortest setting to fit it in my car's tiny trunk, and I lengthen it to the longest setting when I'm using the detector.

    To preserve battery life, I turn the detector off when It's located something. Then, I use the Garrett Pro-Pointer to narrow it down even closer, digging as needed. I turn the Pro-Pointer off ASAP to preserve its battery too. On the other hand, If I'm in an area that's chock full of coins, I don't bother turning either device off because doing so would slow me down too much and not save much battery life. Speaking of batteries: both devices take standard 9-volt batteries. I haven't had to replace the batteries during perhaps 20 hours of use!

    Aspects that surprised me:
    * It beeps if it bumps into something hard, such as a rock. At first, I thought it had found metal, but re-sweeping the area indicated no metal.
    * It is more sensitive when sweeping left and right than forward and backward.
    * It doesn't discriminate (between trash and non-trash) as well when sweeping fast as when sweeping slow.
    * Normally, it has to be moving to detect anything, but if the signal is very strong (such as when the treasure is on the surface or is large), it can basically be motionless and still beep.

    I haven't used it with a headset yet, so I can't comment on that aspect, but the built-in speaker is plenty loud for most of the places I've taken it. They say the battery lasts longer if you use a headset.

    I was debating whether to give this product 4 stars or 5. I decided to give it 5 stars because, for the price, I can conceive of no way at the present that anyone could improve upon it. Still, wouldn't it be cool to have a device that could definitively tell you what's buried down there?
