question about transducers

bridgeman · #1 02-26-2009, 09:04 PM

I have a furuno fcv 620 and need to get a tranducer, not really wild about drilling any more holes than neccessary in the transome so I thought about getting a shoot thru hull design but when I researched it stated that it won't work on cored hulls (don't know if I have a cored hull) don't feel comfortable drilling a large hole in the bottom of the boat to install a thru-hull. Don't know what to do at this time and have to make a decision in the next few weeks, thinking maybe a transome mount on a mounting board sealed with 5200 is the way to go.

The SeaCraft hull is not cored so you could shoot-thru. I think I saw that Air-mar now makes angled transducers for this purpose. You will lose some of your depth range. Dave

I have the same unit I put on my boat last year and I installed an Airmar B60 600w tilted angle thru hull and it works awesome! You have to get a separate temp unit if you shoot thru and I don't think you will be happy with the performance of the transom mount while running. Mine reads great until the boat launches...don't miss out on all that unit can do by skimping on a transducer. Winching the boat up on a roller trailer will not harm the thru hull. Godd luck with whatever you decide!

I got a Furuno 585 last spring and installed Airmar tilted transducer- it's virtually flush on botton of hull. I too hated drilling a hole in the bottom of my boat,but did it anyway and performance is great. But, while shoot thru's supposedly lose some of their power and potential unless you fish very deep water it may not matter to you.
