You don’t necessarily need a separate pole. I’ve seen some people mount them directly to their bow mount.
Obviously if you intend to use it for open water and ice fishing you’ll need a separate pole because I don’t think you’ll be lugging around a bow mount while ice fishing.
No ice around here. I’m thinking a separate pole since the bow mount trolling motor has spot lock so it will be adjusting its position on its own to hold the spot and might point the transducer away from what I want to see.
Yes it has to be aimed.
3 in 1 would be mounted on back of boat and plugged straight into head unit.I wouldn’t want active target as my only source of sonar I know that.
I already have a conventional fish finder on the boat’s console but I still might want the extra capability of that 3-in-1 especially since I can’t see the console-mounted one from the fishing position, just when I’m driving the boat. Still debating that with myself. I’m wondering if the 3-in-1 transducer cable will be long enough as it’s a large pontoon boat and the cable from the rear of the boat to the bow will be something like 20 feet minimum, probably a little more since I’m sure I won’t be able to run the cable in a straight line.
