AcuRite 02020 Portable Lightning Detector Black, 2½L x 1W x 2¾H

Arrived after a long journey from the USA to the UK. Apparently we don't stock lightning detection devices over here in the UK? I Opened the package and installed the two AAA batteries. Powered on and its working fine. Now just waiting on our usual bad rainy and stormy weather that comes from the Atlantic and across from the East Coast of America. Looks quite an impressive for a small compact device. Similar to what scientist Travis S. Taylor wears on his belt. As I am building a Sky360.org UAP-USO monitoring station with very sensitive equipment, I want to protect my sensors and monitoring station. This lightning detection device, will help me detect dangerous situations that can damage my electronic and photographic monitoring system. Thank you Amazon Prime UK for transporting from the USA to the UK 🇬🇧 for free on Amazon Prime.Post ScriptI have been running this device since delivery, it works perfectly fine. Recently, on one day it recorded over 36 lightning strikes within a 7 mile radius. It is great working inside the house and outdoors. It accurately shows lightning strikes and is a great warning ⚠️ device for anyone working outdoors or with radio communications equipment. I fully recommend this man portable wear on a belt device in case you need warnings of impending lightning strikes. If scientists like Travis Taylor wears one, then why not anyone who needs lightning detection whilst working on radio communication equipment.

Excellent product, does what it says, used for my interest in storms. Easy to carry around

First things first, it does work and does pick up lightning strikes BUT there's some things you need to take into account. Firstly it's just a basic detector - it's not going to tell you accurately the distance etc because it's just a single unit trying to work out the distance of different strength lightning strikes - even a expensive detector with a fixed single antenna mounted well above any obstructions needs lots of strikes and really good software to work this out. It won't tell you where the storm is in relation to you because it doesn't have a fix antenna (or built in compass and accompanying software) to work out the angle of any strikes to the unit and you. But it does give you a idea there's lightning about and a very rough idea of how far away it could be. I have seen some reviews that say there can be strikes and thunder heard but the unit beeps and says the unit needs moving and doesn't say strike etc - mine did the same until I moved it up above surrounding properties so just like a fix units antenna, it needs to be fairly clear of obstructions. So basically it is what it is - a low cost detector which is good just to have if your out away from all the modern day interference and any solid obstructions.

Quite good for the money. Detects thunderstorms at about 25 miles or less and fairly accurate when compared with lightning portals. Works well on the default setting as delivered.

I purchased this to take in our caravan as thunderstorms always seem to follow us. This weekend was the first time I was able to test it and it worked after a fashion. It has two modes - Indoor and Outdoor - and certainly picked up the lightning strikes. The warning light flashes and there is a beeping sound at each strike, however the LCD counter seems to get stuck at 3 and eventually tells you to move the unit as it cannot detect anything despite continuing to flash and beep. Comparing the unit to my main lightning detector, the flashing/beeping strike rate indicator and distance indicator seems to be reasonably accurate. As with everything, you only get what you pay for, and the P&P and import duty cost more than the unit itself!

Works great it picked up lightning before I knew it was happening , had it on a window sill , in outdoor mode and checked it against an online one and it was great …

The device arrived on time and looks a great unit. Upon putting 2 AAA batteries in, I found that the battery cover did not clip in properly at all, the battery cover just kept falling off. Would lose it along with batteries. Rubbish design so sent it back. Shame because had the potential to be so much better. Didn't get a chance to use it. Won't be ordering another. Avoid.

The item arrived today instead of Thursday which was a bonus. Easy set up and use. Only thing I don't like is that you can not register product in the EU.
