Late notice, but if you're in the Longview vicinity Shipps Marine in Gladewater is hosting a seminar with Lowrance and Hummingbird reps. It's about a 2 hour program and they can help you with any questions or problems you might be having. Tomorrow is the last day if you're interested. I believe the meetings are at 10am, 2pm and 5pm. Might better call and double check those times.
