I was out for 8 hours today using spot lock with no issues. Looks like I used about 255 battery which is normal for my 100ah relion lithium
I've used that same spot in the past for a heading sensor so I knew it would work. It does have interference when the trolling motor is stored, but I only use it when the motor is deployed. I have a second heading sensor puck on the rear of the boat that's used by the console unit
I finally got to test everything today and the ultrex worked flawlessly. It really is a great addition for the way I fish. Pairing of the puck was instant and I did the calibration, offset and boat offset settings without issue. I did have a cable issue so we may reroute everything when we install the new 360. I may even try running everything down the trolling motor cable and pray I don't have interference. The only thing I'd like to add to the motor is a tension adjustment. The pedal is a tad touchy especially in big waves and wakes. I'm sure I'll get used to it though.
