Hi Fred,
I agree on the bow vs stern and turbulence points. I thought about that as
well. The thing is, I have no plans to use this while underway (The
charplotter itself will take care of the depths while underway) . In fact
there are a couple "More reasonable" bronze HD transducers in the 700.00
range I could install on the spot where my old depth transducer is, ahead
of the keel and neater install / more functional but I really don't want
the drag for racing
This would strictly be for picking an anchoring spot, do a couple slow
motoring flybys to scan the area and pick a spot where I wont snag a tree,
car, house, or something else stupid, then anchor. The lake is a submerged
valley complete with streets houses a gas station and other stuff..
I might use it to see if there are a few fishies we could snag for a fresh
dinner however..
You gave me an idea.. I might not mount it at all and just make some kind
of pole arrangement that could be hung from the bow or stern pulpit when
needed and stowed the rest of the time.
Thanks,
-Francois
Given that the bronze through-hull Structure Scan transducer is $1200+, I?m
not surprised that you would try the skimmer. Just remember that you?re
going to have to be sailing flat (or motoring) in order for it to work with
any degree of reliability, or even be underwater at all, given heeling; and
there may be enough turbulence off the transom that it won?t read well,
unless you?re just barely making way.
Also, at the transom, you?ll bee seeing what the bow already passed, rather
than what?s below it.
