If you wheel with Overlander when he leads then yes you need one. You've already dropped over $40k into your current build, buy the Lowrance and do it right.
Thanks to friends new and old for such a great time. Special thanks once again to Eddie and Cindy for organizing such a great time and getting everyone off the trail.
You wouldn't happen to have a rear driver in silver would you that you would like to part with? Mine met rock. If so and you want to sell I'd like it. Thanks
