I ordered this detector through Kellyco, but I did alot of research and first saw this compared to the Garrett Ace 250-350 models. At the price point it is slightly above the beginner low budget models, but somewhere in the lower middle range of power and features.

To start, I was a complete newbie to metal detecting. I was attracted to this detector because I want to dip my feet into metal detecting. There is a youtube channel(PondGuru for those interested) I watch where the owner shares his metal detecting finds and this inspired me to get into the hobby.

So the review. The great thing about this detector is it's ease of use. You can assemble the unit fairly quickly right out of the box and a brief glance at the instructions will allow you to know the basics. It does not come with a 9volt battery so you need to have some on hand. I recommend getting some rechargeable ones here on amazon. (No heavy duty ones.)

It is EXTREMELY light weight, not much heavier then a broom and very well balanced while swinging. The coil is not heavy at all either. It is very sturdy and no flopping about or jiggle.

The display is digital and provides nice feedback on targets in the ground. It gives the estimated depth in inches (up to like 8" or more), while the different modes will tell you what material it is detecting. It outputs a number that can be used to determine material and signal quality... though I found it a bit to bouncy to make accurate determination. You can search for ALL metals, or use the handy discriminate mode which allows you to custom pick and choose which materials are detected while ignoring foil, aluminum pop cans or iron targets like rusty nails. The pin point feature of the detector is nice, as holding the button down allows you to move around and hear a audible tone as you near the target. Great for final "homing in" before picking up a shovel.

I have spent two solid days swinging around in my yard, learning the different tones. I found a variety of junk around my home. A die-cast toy plane (I lost it 20 years ago!), a shot-up fire extinguisher (riddled with bullet holes but the metal detector screamed at me when I was over it), lots of bullet shell casing from hunters, tons of rusty old fashion farm nails, pennies, wire... The people who lived here previously were fairly poor so I don't expect much. No real amazing finds yet, but I have grown more confident and I am already planning on new sites to visit.

I feel this was a great detector to start with, and I am already interested in perhaps getting a larger coil for deeper detecting. I would also HIGHLY HIGHLY HIGHLY recommend getting a pinpointer to supplement your hunting. This detector is great for getting on a target, but once you dig you will struggle with finding the item in the hole. A handheld pinpointer is useful because you can probe a hole and locate the item in the side wall or in the loose soil. It will cut your time in a hole down dramatically.
======================================
EDIT: I uploaded a youtube video showing my finds over about two afternoon days. Alot of misc. items and junk. Some coins too. Should give you an idea what this detector can do. [...]

EDIT 2: Just a quick quirk I noticed. This detector is sensitive to power lines. If you swing directly near or below a line, what will happen is it will beep sporadically across the spectrum of metals randomly. Dropping down the power sensitivity to a 7 or 8 reduced it. It also did this with our Inground line dog fence. Turning off the fence stopped this false tones. Not a big deal at all, just in case anyone else encounters this.

I just opened my Delta 4000, assembled it (easy to do). I went to a park where I often hunt with a Bounty Hunter and with a Garret Ace 250. I did not expect to find anything, not even trash, because I thought I have cleaned that playground very thoroughly. During the initial test, and after just a few beeps, I dug up 2 hot wheels and one dime. The pin pointer beats the other detectors I have (the item is not in the center of the coil but rather to the front between the 2nd and the outer ring). The Target ID is great but I always dig every hit because, in my experience, you can miss valuable targets. The delta is rather sensitive and kind of noisy, but you can use small headphones. I still have to test how it works in trashy areas. I love the fact that you run it with just 1 9v battery which beats my bounty hunter. I love the target numeric ID that I have only seen in the higher end metal detectors. I have researched and I have only found positive reviews and no one can beat the price for what you get. The higher frequency (7.8 khz) than the Ace (around 7.2) helps with relic hunting. I must say that I live in a dry environment and I would like to learn how it works in mineralized soil.

I purchased this item last fall and, unfortunately, was only able to get out a few times before the winter set in...
This was my first detector purchase. I bought it after reading enough positive reviews to make me feel comfortable about doing so. I quickly familiarized myself with the Delta's functions and headed off to the beach.
Oh oh.
Sadly, I didn't have any prior knowledge of the difference between what is basically a digital machine and an analog one. Salt water is highly mineralised; a digital machine such as the Delta thinks that the water itself is a metal object, and will therefore alert to the presence of metal, when you are simply swinging over wet sand.
This type of machine absolutely cannot be used in wet ocean / beach sand, nor in the salt water itself, which I quickly learned. For a salt water environment you are best served by a PI (pulse induction) machine, or a machine that specifically states its useability at the beach. I saw all the 'pros' down there by the edge of the water / in the water at low tide, pulling gold out of the mud, and suddenly felt like an amateur, ignorant...and sadly, unable to join them down at waters edge.
It can, however, be used with much success in beach sand that has dried completely; the soft, white sand towards closest to where the beach ends and the mainland begins. Unfortunately this is also where most of the trash, i.e. pull tabs, tin cans, garbage, etc., are found. I did manage to pull up some coins, a couple hot wheels cars and a few other worthless trinkets. I still had a great time.
That the bad news, or rather, the not so good news. On to the better stuff...
The machine will work just fine in and around fresh water; ponds, rivers, streams, etc. These are great places to hunt and I highly recommend them. Fresh water areas seem to be a great place for finding valuables. Much of it has not been hunted, and I believe it to be a potential treasure trove...if you can identify the right spots to hunt. I was able to get over to a fresh water pond beach for a few hours. The machine was singing. Unfortunately it was mostly trash. Found some clad coinage, though.
Next I headed over to an elementary school that was built in the late 50's.
Here I was able to finally see the machines' capabilities, as I learned to best tweak the settings to suit my environment. The machine is very accurate in terms of finding coinage. If it says there's a dime down there at 5, 9 or 12", there's a dime down there. Same with a quarter, etc. Same goes for depth. The VDI / depth indicator has been scary accurate.
I was pulling quarters or of the ground, one after the other. Unfortunately no silver, but a nice handful of clad in a short time, getting very comfortable with the machine.
Next I headed off to a late 1800's estate, thinking I was going to find something good. Not. May likely have already been hunted - a number of times. Oh well. Found a bunch of iron, though, as I decided to try digging up almost everything, just to see what was down there, and better know the Delta. Lots of cut nails, horse shoes, etc. Nothing precious or noble. Yet.
I have had the winter to study and mark possible / future hunting sites, and I look forward with excitement to finding some good stuff this year. I will be going into more deep woods / trails / off the beaten path kinda places this year, where the chances of trash is minimal and the chances of finding silver / noble metals is much greater. That's where I see this unit in all its glory. Old homesteads / farms / corn fields, etc.
I really like Teknetics, but I do intend on either getting myself a PI machine for salt water, making one myself or upgrading to a machine like the Garrett AT Pro that works on land and sea equally - and also works underwater...or at minimum a machine that allows me to adjust the Ground Balance, something the Delta does not, so I can 'tune' the machines frequency to best suit different levels of mineralization in either wet or dry ground. Either way, I can tell already that I am hooked on this hobby.
Bottom line: I highly recommend the Delta - if that is the price point you are at, or as an awesome first machine. Teknetics machines provide some of the most advanced features for the money; after all, they have been in the MD business for decades.
However...depending on where you live (like along the ocean / the coasts, as I do)...and/or what kind of soil you intend to hunt....I might advise you to be patient, save up a little more money and get yourself a machine with adjustable Ground Balance, like the Teknetics' Gamma or Omega - or a machine that is equally capable in both salt water and dry land...
If you do not want to / do not plan to hunt along the ocean, then this machine is a must have for the price. In my opinion...as well as that of many others...it will rival / outdo machines costing hundreds more.
* Five Stars * (for the price, understanding that it is not an oceangoer...)
I'll update after a few more hunts.
Happy hunting!

Fast recovery and very deep for the price, purchased for $165.00. It has been a fantastic detector for the money, great for mild soils where no ground balancing is really needed. Very fast recovery for trashy areas and good discrimination. Not a good detector for salt water beaches or highly mineralized soils.

Not many reviews on shopping sites for this detector.... I looked over alot of forums. Many people seemed to have difficulty with the Ace 250, or not very positive things to say. Almost every post and youtube video for this detector seemed to be positive.

Ive had it about 2 weeks, and used it maye 3 hours. Im not a millionare yet, but have found some cool stuff. The more i use it the better i am with its settings and interpretting tones. So far the LCD has been awesome and pretty much on the money with what it picks out. Only thing is as with most detectors, gold and silver show up in the lower numbers, so you cant always dismiss the lows as trash.

For the money this is a great metal detector ! I hunt with a guy that has metal detected for 30 pluss years and has had several different brands and he currently has Teknetics now..its a step above this one but does every bit as good . I would recommend this to anyone thats on a budget !

Great online reviews for this model. Had a garret At-Pro that was twice as heavy to hold and carry compared to this model. it's not waterproof at the housing like the At-Pro, but I don't use it in water deeper than two feet. Probably one of the best detectors in this price range.

I had purchased this for my husband as a gift and he absolutely loves it. It is durable and works great. He has already found things in our own back yard. All the different settings lets you locate several types of metals. Great unusual gift idea.

I did a lot of research before buying my first detector. This looked to have a lot of bells and whistle and it did. Does take time to learn everything but it works very good. Still trying to learn everything but it is something fun for me and my son to do together. Will post back later after more use but so far a good buy.

Very solid detector that is great for beginners. The pin pointer is very accurate along with the depth finder. Discrimination works well. I like that it has a volume control so you can use ear buds instead of detecting headphones.

For the money, there's nothing else to compare it to.
