Yes Sir, I have one and love it. I don't have anything to compare it too, but it works great in fresh or salt. I just can't seem to get out enough. I have the 8" coil, which I wish was the 12" (not interchangeable). The electronics are all in the headphones. 40 hours per charge.
It's a beep and dig, but the tones really tell you what it is unless you are in all metal. A repeatable tone is coin, ring, pull tab. Anything with a click to it is washer, bottle cap, hair pin. I like to guess before scooping, most times I'm right.
I've only found 4 gold rings with it so far, but every one gave a good response. They have discontinued the 8" coil, so you may be able to find one for around half price with a 90 day warranty.
Also, the machine has a straight cable, which I love. It doesn't get tangled like the coiled cable. With all the electronics in the headphones, it makes swinging really easy. You will really notice it when you come out of the water and swing up the beach, it's like swinging a wooden bat, then switching to a wiffle bat on shore. I usually have volume maxed for deeper whispers, but a quarter will blow your ears out. I've done better head to head with a nox800 using friend, but I think that is just putting the coil over a target. And for traveling or diving (which I don't do either), the shaft is 3 sections for easy transport or short shafting.
I don't really know how to measure my deepest finds, but a buffalo was two full scoops deep from my T-rex scoop and my only salt water ring was 3 scoops.
When I was looking for a water machine, I had the ATpro in one hand and the HH in the other. So glad I picked the HH, especially hearing later on that the AT didn't work in salt.
Problems I did have with it. The batt died in the first year. I sent it back and they fixed it no problem. He said I overcharged it. Haven't had a problem with that since. I only charge for two hours max now.
The plastic piece between the coil and the shaft snapped while detecting. $10 for a replacement. I hunt rocky rivers/ponds so constantly banging against rocks. I think that was 3rd year.
Last year (5th), I was getting a lot of falsing in fresh and salt. I sprayed the coil with Flex Seal. I had a pin hole in the coil. The flex seal worked great and stopped the chatter. Sometimes I have to swing against my scoop just to make sure my batt didn't die. Also, the flex seal is white, so now I can see the coil better under water.
I was always amazed that the DP HH UW doesn't get any love on here, but it's not a well known detector I guess.
Again, I've never used a Nox, CZ21 or Excal, so don't really know how it compares. I think it's a great machine. It works equally well in tot lots and dry ground, but I don't use it in real trashy areas, I get out the MXT for that.
