Transducers

[Scotto]

Nice install Jim. Thru hull is the way to go just be sure to use the fast cure 5200 (which you can also get in white). The regular stuff can take a month to cure. My only question is why you did not use SS counter sunk bolts with SS fender washers and nylock nuts on top instead of screws? Not that I think you would have any issues with screws but curious what went into that decision. I have built and rigged many skiffs and was just wondering. My yak is old school with no FF since I don't use it very often.

Good 5200 story, I had to torch and sledge hammer out my last bronze transducer which I used 5200 to install (it failed) in my boat. I have drilled 7 thru holes in my boat and none leak. I once had to use a forklift to get an engine bracket off a boat that was adhered only with 5200 (bolts removed)!

I just purchased a new Garmin FF. Does anyone know if they or any dealer will exchange the transome mount ducer for a thru-hull type?

Com'on F/F is useless without one of these

[peguinpower]

Dang Iceman! Why'd you have to take it up a notch BAM! I want one.

Glad to see me and Jim are not the only ones that jumped off the thru hull cliff

Its not for everone, but I have not regretted it.

Not my ride Bing, customer wanted F/F moved up to the sail mast. Had to pull the Kayatank and saw the lil yellow box inside.

what is that yellow box and what does it do?

It reads and records barometric pressure. It actually does more then reads it but stores it in a 12 hour buffer allowing you to access current and past data to see if there have been pressure changes and what the trend is.

The higher the atmospheric pressure the more water it can hold in the air. So usually when you get a dramatic drop in atmospheric pressure your going to get rain. Cold fronts that produce rain are actually low pressure fronts.

Water is more dense then air and when the air pressure changes it creates micro changes in water density. For years and years people have said that fish bite on a falling barometer, but the question has always been why.

My take is that baitfish do to there small size have trouble dealing with changes of temperature PH or pressure. When you have a dramatic shift in barometric pressure, it can produce a small change in water pressure, which can sometimes disorient bait and make it easy prey.

This is the same reason offshore fish feed on temp breaks. Baitfish when they hit a break get disoriented as their bodies adapt to the temp change which makes then easy prey for larger fish that are not effected by the small changes due to their increased mass.

Whatever the reason fish tend to feed before storms, and they somehow have a way of sensing storms are coming. I'd say they have some kind of ability to sense the rapid drop in pressure which signals the storms are coming.

In a way that box just gives the angler the same ability.
