those of you that have it is it worth it? has it helped you to stay located on offshore structure and cover?

Had it...used it...loved it! Yes it will help you stay on spot, but that said, It's not a Precision-9.

I also have the Lowrance OutboardPilot auto-steering unit. I switched from Point-1ap to the Precision-9 to help with the drifting of the AP while at speed. I have not been in the water since making this change so I have no update yet.

I have it, use it.  Gives me a common point of location for all my units since they are networked.  If you get it just relize when you mark a spot the waypoint will be where the point-1 is mounted.  I've seen some people use two (one for the bow and one for the console unit).  

yeah im thinking about just getting 1 mounting it by the console amd linking to both units. if i can get with 10 feet of it surely i can find what im trying to fish.

The Point-1 is no more accurate than the GPS sensor in the Gen 2 or 3 HDS. The main reason to use a Point-1 on a bass boat is for heading. This stops you maps from spinning when not moving when using heading up. It makes it much easier to stay on waypoints. Another benefit is being able to install it near the transom mounted transducer to give more accurate waypoints. You want the GPS sensor and the transducer to be at the same spot. There is no reason to install one at the bow because you already have a graph with its internal GPS right next to the transducer on the trolling motor. With a Point-1 on the transom, the bow graph uses its internal GPS and the heading from the Point-1. The console graph uses the GPS from the Point-1 as well as the heading from the Point-1.
