we bought my dad a v1 for his birthday. let me just say that this is the sweetest detector on the market. wow it is amazing. this thing gets signals from very far away. i used it to bring my svt home from dallas and it would give me a beep and i wouldnt see a cop for a couple of min. i love how it also tells you how many signals it gets and wear the signals are coming from. i think i am going to have to buy my own, or steal his when i go back to school.
