EcoVisor F4 Geiger Counter Radiation Detector Dosimeter Nitrate Tester EMF Electromagnetic Electric Magnetic Field Device Water Quality TDS Meter Portable Electronic Touch Screen Easy to Use

I will start by saying that this is a great, compact piece of tech. Along with the functionality of the geiger counter, you have an EMF meter, a feature to measure water hardness, and a feature to measure the level of nitrates in a variety of different foods; those being fruits, vegetables, and meats (including fish).I have read complaints about the battery life being short, and thus far I have not noticed that, but as with anything that could be subject to change. I power mine off by holding the "OK" button when I'm not using it to conserve battery life. One thing I did notice, however, is that the clock does not stay current; for instance, say that I set it for 9:30 at 9:30 in the morning, and I turn the unit back on at 2:15 pm. The clock will say something like 11:20. This is my only criticism of the product, and I do not believe this to be worthy of a drop to four stars since this is a trivial feature.All in all, I would absolutely recommend this unit. If you're on the fence, I say go for it! If it doesn't work for you, you can always return it.

I love mine. I have carried it for years now. I have since put velcro on the back and keep it on the dash of my truck facing me. Only 2 minor complaints. The rechargeable battery discharges quickly, so I keep it plugged in the charging port. Also the test probe cap on it easily falls off and it is a necessary part. There is a small switch that detects when the cap is removed and automatically switches to the nitrate tester. So do not lose the cap.

I cannot attest on the accuracy of this unit but it was working reasonably well until put in storage for a while. After pulling out of the shelf it was turning on but only working for about a minute and then shut itself off. I fully charged it but that didn't help. Battery apparently are not made to be replaced as it is quite hard to disassemble the unit. But after taking back cover I realized it's just a pair of AAA rechargeable. I just plugged in regular Batts and it is working fine. I still have yet to hear from customer service. Price is quite steep for the product imo, there are better options around

I actually have no idea if this thing ever gave me proper readings because Im no expert, but I gave it 4 stars because the battery died after a year. Thankfully you can plug it up with an external usb battery pack for phones and keep it going.

I have had my device since 2018 I use it all the time especially for water. I suspected my daughters well water was contaminated and sure enough 285 with particle detection alone. I now use a water distiller for water because our RO system didn't seem to be the top of the line it was supposed to be, it's got a high reading of particulants distilling tells a lot about what is really in your water. I tried San Bernardino water, it was high but after distilling the water what was left smelled so bad. It was this awesome gadget that made me aware of just how much junk in our water and food.I wouldn't do without this for radiation, nitrates and particulants in food and water.An absolute must!

The media could not be loaded. Before we purchased the Soeks Ecovisor we didn’t know how bad some of the foods were that we were buying at very well known stores. Our shopping list and our life has drastically changed since.When we grocery shop now we check everything that we are able to test before we purchase it.It is ACTUALLY SHOCKING how many different foods that actually claimed to be organic had extremely high levels of nitrates in them. We have no problem with letting the stores know what they are selling. They actually appreciate it most of the time.We are instantly informed of the foods quality before we buy it.Thank you SOEKS for providing us with such a easy to use tool that simplifies our buying decisions.

I wanted to use this to test for fertilizer nitrates in ‘organic’ vegetables before buying them. They do test well at home. Also wanted to check water safety as I travel. This unit only tests ph. I have found the electromagnetic feature very interesting. Radiation seems constant so far. If I were in a radiation situation this would do little good as it barely holds a charge. With any use at all the charge depletes. Even with no use. It takes a long time to recharge, even when not depleted. I keep this on a solar charger much of the time. It would be more useful if I could put it it my purse to carry around. I hope the flaws will be addressed as I use it (I like the small size) and would love to make more use of it.

This item is a MUST HAVE! Unbelievable all fish has in 5 times more nitrates, than it must has. 1000mg/kg instead of 200mg/kg as a norm. All smoked and fresh not organic fish with nitrates! A lot of watermelons with a high concentration of nitrates. Very reccomend this product!Update:The item works great despite battery issue.
