There is an Etrex H and an Etrex Venture HC. I think you are referring to the latter. It is a good choice for someone who has a GPS in their automobile.
As others mentioned automotive units aren't a good tool for the job. They are built for the dashboard, not the outdoors and usually don't have some key features like extended battery life, compass navigation screen and
water resistance. Some don't even allow you to input coordinates.
Thank you all so much for the reply s I'm looking forward to my first cache
