For those that haven't figured it out yet the clone manufactures are busy making copies of the FS1 meter. If it doesn't say First Strike Meters on the face plate then you are getting a clone and Ebay has a ton of them for sale. Today I came across a model that I thought was something new from them, but after Emailing First Strike it appears now another company by the name of Orbit Trackers is selling a clone under the model name of Tracker Light. At first I thought they might have a manufacturing agreement but I was told that's not the case. Just a clone! If you have any questions just email them at First Strike Meters [sales@firststrikemeters.com].
