Si on a trolling motor is mostly useless. Every time you turn the screen blurs.
Si you sit at console and drop way points on rock piles weed edges , ledges so trolling with rods in holds
would work, you need to stay at 2 mph and drive strait or it blurs. Lake Ont useless.
Bacon has a pic of 360 much different than SI. It's like a radar circling your boat and takes some practise to intrepid.
Works well on trolling motor when fishing. Price $1500 for transducer , a 9-10 inch dictate unit to 360 and then you can network with other units. Price 4k.
Then we could talk about Garmin Panotics wick expensive.
