Off looking at flashers and had pretty much made up my mind on a Marcum, but stopped by Throne Bros yesterday and they told me that the Marcum may interfere with other flashers in the area and the Hummingbird 35 (which has pretty much the same features) will not cause any interference????
Both seem like good units but I could see going to a 35 for this feature.
Anybody??
