Was out yesterday with new HDS 7 Gen 2. I feel a little better about sonar settings, may need a little more OJT on colorline and sensitivity Having problems learning the GPS side. Map showed state of Virginia Called Lowrance and the lady told me to zoom in on map, This took care of my problem. Have heard alot about customer service at Lowrance. I have called several times. Those that I have talked to have been very helpful and patient. Maybe they just know that it takes us "old guys" a little more time to catch on. I am sure I went through the same learning curve with my old unit. Can't wait to get back to serious crappie fishing
