I got out yesterday and played with the new toy. A few observations:
Keep it far enough below the waterline so as to not suck bubbles down across the sensor. I had the mounting bracket sticking up a bit above for the first couple hundred yards and moved it. Got lots quieter.
It does cause a small amount of drag and will pull the boat around like a rudder. If you are paddling any distance between put-in and fishing its best to remove it and save batteries.
If I rocked the boat just a bit I could ping the same fish multiple times. Also, paddle turbulence past the sensor showed up on the screen as a sudden up spike in depth.
My brand/model is a lot easier to "mount" in the boat than that shown recently in the Paddling News streamer. Just remember to tether it in case something like a big fish hits your boat and rolls you over.
I was paddling after lunch and the big fish were between 50' - 150' deep loafing around where it was cool. Not fly fishing stuff for sure.
