"Trolling around" and constantly moving.... is why the heading sensor doesn't make much difference for you. As long as your moving enough for the units to detect your direction of travel, you won't have any issue with the map.

I'm not a trained expert with lots of technical training in gps, in fact you could say I'm pretty much a nobody and offer no credentials as to why anyone should listen to what I have to say. However, to say that people have been "sold a line of crap" about the Point 1 antenna, I would have to respectfully whole heartedly disagree with. I used my units for a time period with out the point 1 antenna. After adding the point 1 antenna, I instantly saw benefits in having the accessory, for the way I fish. Some people have it and don't set it up right to get the most out of it. Some have it and don't properly install it correctly and others read things such as you posted and believe it is a worthless piece of equipment and never experience the added benefits it can provide.

The most benefit can be gained for the guy that is not an expert and just wants to have things set up to make fishing offshore structure as easy as possible. It helps the guy that wants to pull up to a brushpile or multiple brushpiles and sit still and know exactly where they are located in relation to the direction your boat is pointed. It's awesome for someone targeting a waypoint that is casting distance away to know that you can be at any angle or direction from it and still look at your map and easily know you are pointed directly at it and hit the target much more consistently.

Everyone is entitled to their opinion of everything. I just hate it when someone's opinion of something can ruin it for someone else that could actually benefit from the equipment. However... I want everyone to realize.... I am obviously not an expert. Just someone trying to help based on my experiences.

Thank you for your service sir!!!
