Been lurking a lot, but finally registered! I'm a new owner of a Corvette C5 as well as a Uniden R3. Very interested in countermeasures, and look forward to turning the interior of my car into the cockpit I've been dreaming of.
Uniden R3 is a top tier RD. With that ride think about an ALP install as well as using Waze or other available counter measures.
I am the perfect example that old dogs CAN learn new tricks! This Forum is packed with tons of useful information from best detector for where you live and drive mostly (so far there is NOT a single detector that is best for everyone/everywhere), proper mounting possibilities, additional counter measures, fast but intelligent driving habits, and of course Vortex https://www.vortexradar.com videos!
Welcome to the forum from a fellow Texan. Your R3 should serve fine considering you have a Vette. Please keep in mind that DPS employs instant on radar almost exclusively so any 34.7 KA band alerts on interstates/highways and back road will be legitimate. With that said do not be the only car traveling on the road as you will surely receive a citation if you are over the officer's speed threshold. Let other faster cars lead so they can be targeted before you. Learn to slow down when approaching construction/school zones, overpasses, blind rises, curves, and at night when you cannot see well. Another tactic being used is that a wily officer will come up from behind and "pace" traffic. Once they confirm that someone is speeding expect a blast of instant on radar or a straight roadside disco lights show. Watch your tail!
LIDAR/LASER Enforcement is commonly used in the DFW area and on the I35 corridor between Dallas and Austin. No radar detector will be of any use if your Vette is being targeted. For effective defense you would need to invest in laser attentuators.
Keep in mind that your Vette is an attractive target to law enforcement. If a regular Honda, Chevy, or Toyota sedan adjacent to your Vette is running at the same speed as you and are targeted by radar, 9 out of 10 times he continues down the road while you get pulled over.
Stay safe and good luck.
