C-Scope are actually one of the oldest detector makers here in the UK and possibly the oldest,the best way too describe the company they are very similar to Tesoro,very old school and possibly not the sexiest machine looks wise but they do work,the customer service is certainly about as good as it gets and they will go the extra mile and help customers out.
I dont actually own a C-Scope at present but have done years ago and once again it performed exactly the same way as a Tesoro does,i feel that because it does not look sexy or they dont have a screen they are not as popular as other main stream brands,one detector out of the range that is in my mind a total mind blowing bargain for the price is the C.SCOPE CS4Pi which is a very basic Pulse machine for beach work,for the price is offer amazing performance for the price,if you are on a tight budget for a Pulse beach detector then this model is outstanding value,regarding the CS4MX model and also the CS6MX these are both reliable workhorse machines and will perform well for many years.
So that basically is C-Scope in a nutshell,the UK's version of the Tesoro,that about sums the company up,they provide reliable detectors that work but still in a time warp from the 90s.
Please note i have no connection with this company,just my opinion from observations and also a previous owner/user.
