Ulterra Anchor Mode Question

[Specktackulure]

Trying to figure out what is going on with the Ulterra. Here is the scenario, 25 foot boat center console, Helix MEGA 10 at the console, Ulterra on the bow, transducer at the stern. Helix and Ulterra are connected. When in anchor mode with just me or another person anchor mode seems to work fine. The other day I had my brother and his 2 sons with us, we were from the center console to the rear of the boat fishing and the Ulterra seemed to have trouble keeping us in position. It would go into the fastest speed to get into position then pass up the mark the reverse back in the fastest speed and then pass up the mark, and then repeat the process over and over again. Now when I would walk forward it seemed to work normal and hold us in position in a more normal steady mode. What would cause this? I just cant imagine that the transducer being an inch deeper in the water would cause this issue, nor the bow of the boat rising an inch either. I am using an inch just as a metaphor. I have no idea if it rose or fell that much. Ideas? Thanks

The only time my Ulterra gen2 acted like that was when I first got it and I had not adjusted the Boat Scale for the size of my boat (+2,+1,0,-1,-2). Is it possible that your boat scale setting got accidentally changed? The only other thing I can think of involves the Heading Sensor. Where is your Ulterra's Heading Sensor puck located? I ask because mine is on the stern of my boat with my Ulterra on the bow. I suppose it might be possible to obstruct the signal between the puck and the Ulterra. Since the TM uses that signal to fine tune position if it were disrupted it might cause erratic behavior.

Depends on his Ulterra model the earlier non-Bluetooth models do not have boat scale adjustment. OP do you have the Bluetooth version?

When this happens, try lowering the Ulterra deeper into the water. If it stops, you will know that many people in the back of the boat raise the bow enough to prevent the motor from getting a good bite on the water and make it wander too much

If it is the newer Bluetooth version, one other thing to think about is with the more people on the boat adding additional weight. This could effect the boat scale setting. The boat scale setting for one person in the boat maybe different having more people= more weight.

Thanks for your responses, the Ulterra does have the bluetooth, will have to check on the scale issue, and then try adjusting the height while others are in the boat. Heading sensor is located on the center console. I do not think it was obstructed.

If the boat is loaded wrong(everybody in back or all to one side) that makes it very hard to make corrections. Bob
