guys who would be interested in a parking aid thats measured by laser. i have delved into this subject with great detail and have found the best in my opinion, product on the market. obviosly these have a side effect which i can guess you all realise, but as they measure distance with an audiable beep they are legal.
check the website at

these sell at £295 but i have arranged a discount on ten or more for £225

if interested please let me know by pm
