Kayak Depth Finder DSI mounting

[TNriveriscrappie]

Hey there, I'm looking for some wisdom doing a Hull mount with duct seal putty for my Lowrance Mark 4 DSI . I currently have the transducer mounted with a Lowrance scupper mount on my Ascend FS-12T. The DF has to sit I the water at a slight angle based on the way the scupper holes are.

My thought was to do a Hull mount with duct seal ( as I've seen on several threads) . I've noticed it's common for people to mention Side Imaging not working properly doing a hull mount, but would down imaging be hindered as well? If there is interference with DI quality, are there ways to minimize it? Any knowledge would be appreciated!

I have read where one guy did the duct seal/plumbers putty with DI and he stated there was some degrading of the signal but DI was still functional. I don't remember him mentioning SI. I would guess it would depend on the install and if you got somewhat lucky on ducer placement over a "thin" spot in the hull which might help on the signal return. Take some screen shots before and after and post 'em.

This subject has been discussed much on the nucanoe forum.other than a degree or two variation in water temp reading,those who use the plumbers putty inside the haul have been pleased with the results.I myself built a dashboard that incorporates an adjustable transducer mount over the side of my nucanoe.
