I have 2 boats and I'm looking to purchase a fish finder that I can swap back and forth. My first boat is a 24' pontoon and my other is a 14' Alum. I origanaly was looking at the Hummingbird Fishing Buddy but decided against that because it is only good for trolling speeds. So then I was looking at the portable models and I see that most come with a suction cup transducer. Again these are only good for trolling speeds. I'm also not sure if the transducers in the portable models are hard wired in or if they can be unplugged? Basically what I'm looking for is one fish finder unit and (2) fixed transducers so that I can use the fish finder at crusing speeds. Neither boat goes over 30 mph.
lol I'm looking to spend $150 - $300 for one. I'm really only interested in one that shows depth, bottom surface and fish. I'm not interested in one with a lot of bells and whisles. If anyone could suggest something that allows me to transfer between the two boats... allows me to plug into a fixed transducer... and is around this price I would greatly appreciate it. Any addition advice would be great.
thanks in advance.

thanks in advance.
