Yup your all right GPRS & GSM tracker units are very easy to get around with blockers etc and most batterys only last a couple of days if even. I have been involved in this market for years now, The system you need is units that use GSM/GPRS and RF technologies, so there’s no continuous signal to scan for, no wires to cut and no tell-tale antenna to look for, meaning that there’s little to no chance of your unit being found and neutralised once it’s been secured within your vehicle. The units are also self-install so nobody but you knows where it’s fitted. The units will have a 24-hour call centre and we have a team of finders in UK, Ireland, France and other European countries to locate your pride and joy. Your insurance company should also give you a discount as they are Thatcham (Cat 7 Approved) and Sold Secure approved.
We'll be at Ford Fair with an offer and will pass it on here once approved.
