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

August 11, 2011
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!
