Title: simple sonar mount for Hobies
Post by: Thumper on August 03, 2010, 10:59:21 pm
I'm not sure if all kayak 'molded-in' rod holders are the same size, but all the Hobie ones seem to be a standard size. It just so happens that the very slightly tapered shape of a common 40 DR EZY DOSE prescription pill container - perfectly slides into their rod holder holes.
Rather than drill holes and/or permanently mount the sonar (or it's bracket) on the gunnel, I cut the pill container on an appropriate angle, hot-glued it to a plastic piece of old cheap Ikea kitchen-cutting board, and mounted the sonar to the cutting board.
This sonar is removable in an instant, and yet the pill container fits into the rod holder very snug & secure.
Bob's your uncle!

you also might note the small 'earth magnets' from Princess Auto I have glued in my cockpit area. These are great for temporarily holding hooks and pliers and such out of harms way while rebaiting, rerigging or whatever.

Hey that looks like the downrigger setup you were talking about, looks great.

Those magnets are slim and out of the way - they wouldn't catch on anything.

Sorry - I don't recall what kind of glue I used to attach the magnets .... probably the same marine silicone stuff I used to mount the transducer puck in the hull.

Marine Goop may be a good adhesive.
ive used it, and it works wonders.
$10bux at Canadian tire.

one more question about transducers...

does it matter which way the transducer is pointed?

I previously had it pointed towards the stern of my Kayak, but found that the fish were behind me (most of the time) ive now switched it to point towards the bow. (ive yet to take it out since ive made the change).

orrr, will it only show fish that are primarily below the boat?
my sonar has a 60 degree sonar...

sorry im a relitive newb to fish finders/sonars etc.  ive never used one b4.

It won't matter which way it's pointed unless you had side imaging. They are just taking snapshots within that cone so many times per minute. You shouldn't notice any difference.

so im seeing fish around/under me vs in front or behind then?

Yes, that's right - in the 60 degree cone in this case. That could be ahead, behind, or to the sides of the transducer. As the screen scrolls there is the perception of front and back and it will represent the bottom relative to what you have covered  just so long as you don't change direction. The 60 degree cone may give broader coverage, but it loses resolution because of that.

Take a look at this article if you want. It may shed some light on it. The thin side imaging beam must be great:
