How do you intend on using it? Beach or dirt. You can read a great review by Keith Southern on Tom Dankowski site as well a Hugh thread to read...and of course it has its own web sit just started. I personally like the machine for beach and water hunting. It has a black sand setting, tracking, 4 single freqs ... 18, 12, 9 and 6.5 the only single freq machine to easily hunt and be deep in the salt water. An example... we took the Nox and MDT along with a 3 gram white band. At the waters edge the Nox hit it at 12”.... MDT 14”.... moved chest deep... Nox wa 10” and still 14 for the MDT. It IDs iron really well to depth once learned. Tends to upscale trash ... a pull say at 6 will read 6... at 10 it can jump to above a quarter. Gold seems to not very to much. It has a simple TID with back light. 60 digits... 30 ferr and 30 non-ferr. A air testing penny is 13 and most gold fall below that... so honestly I don’t have to dig a lot of iron or high tones. 4 tones ... very distinct pings and pongs. 1 lith battery... $6 to replace. It comes with 2. I’ve had mine and put a lot of hours on it and they read the same as new. Light weight and really great design..... good locks 3 piece it all breaks down and can be put in the travel back pack. I have dug gold rings I’ve had to straddle the hole. I got 6 chains last year. It not only GB the sand but the salt water. This salt GB they are finding can really make a difference in dirt as well on real hot ground. Go to the site and there are some good videos. I run mine in AM.... HOT. Only 1 coil currently 11” but a 12” is in the works for more depth. It’s not a micro gold hunter but loves gold rings and have yet to find a gold piece with any of my water machine this one can’t. He’s not calling it waterproof... but in and out with the box under there doesn’t seem to be an issue. Head phones are good but I’d highly recommend Tony’s if you salt water hunt. It has AM, disc, and mixed mode. 9khz seems to be the better freq in the water. I’ve got no dog in the fight ... I’m just a user and post some of my finds on my FB and their site. Odd not many post finds on this machine... but I assure you they are doing well. In the water most things/machines become equal. For my area I’d say this one out performs them.
