Teknetics delta 4000

January 20, 2012
Bought a delta 2 weeks ago second hand from regton uk. It was broke when I got it . Wouldent pin point on 8"coil. I also bought the 11" coil that worked OK more or less.
Anyway they sent me a brand new machine. What a joke, the broken one works better than this, no depth on either coil what so ever. The build quality is absolutely disgraceful. I've had 12 detectors high end to low end and this is the worst ever.

Finds coins on first 3"inches. And don't say I've got a bad one I've had two. If it was any good they would buy it back, they offered a pittance against a £400 pound machine what does that tell you. I sold it on ebay last night and lost £80 first time ever, plus I sold the 11"coil with it as well. I bought a minelab soveriegn xs 2 for £200, prob 10 years old. Cant see any teknetics lasting that long. maybe 2 years if your lucky. Stick to uk reveiws only and leave the bounty hunters alone thats all they are fisher teknetics are all bounty hunters. Just crap I've learned my lesson this time and to all you parasites out there be a man and bid the proper way not hide in the back waiting to pounce bye.

World class detector for the price , no other comes close.

I have had many other brands including, Tesoro, Garrett Ace 250, ect..
First thing you will notice is the light weight, 2.2 pounds.
It's vdi numbers are vey precise, they will really help to ID targets, like coins, just like other detectors some tabs will have the exact same vdi numbers as nickels.

Also with 2 audio jacks , and a volume adj, this helps to keep the tones at a level you can take.

The pinpointing is one of the best and easiest their is, just hit the pinpoint button move coil till you get the highest number on screen, the object will be in the small hole in the center of the coil. And the number you see when you are doing the pinpointing will be a pox depth.

Depth, if you walk the edge of sensitivity this thing is amazing.

You may have heard about emi, or interference around power lines, this is true, but you can turn down the sensitivity down and in most all cases you will be fine.

The swing speed is just about the same as the ace, but the delta has much better separation, meaning you will have a better idea if there are two targets closer together.

Also the Delta's response recovery time is much faster than most.

It works great in fresh water, only up to the control box of course.

With the amount of vdi numbers in the iron range it should be great for relic hunting as well, I do not get to do much of that where I live.

The build quality is about the same or better than the ace 250, a lot of them suffer from broken arm plastic holders, at least if you watch any you tube videos on the ace people have them broken, I have heard of anyone breaking the Detla's arm holders.

The screen, well its the largest in it's price range, very visible, a must if you have poor eyes.

Also kind on batteries 20plus hours on one 9v.

All and all one of the top ranked MD's for under 300.00, very under rated device.

Overall Rating 5 stars!
