Just thought I'd share a good experience I had with Marcum. I had a cut transducer cable (my own fault). A new one was at least $120. Marcum has a flat rate repair service. For my unit (showdown troller) the flat rate is $65 plus shipping (there and back). So for like $85 I sent it in thinking I'd save at least $25. Well, turns out they found things I didn't even know were bad. Here is what they sent on the work order for my unit: "Replaced ducer with new insulated cable. Replaced membrane overlay, adhesive failed and buttons corroded. Replaced cracked front plastic case." I seriously sent it in just to get the transducer cable fixed but got a bunch of other things I was unaware of taken care of too. Not only did I save the $25 off a new transducer, but after their inspection and repairs I am sure the unit will last me a lot longer! I sent it in over the holidays but it was still done in a couple of weeks- probably only a little over a week of actual business days. These days customer service is pretty poor so to find a company with such good customer service is refreshing!
