SI冰雕有用吗？

[Gorob]

往年冰雕找花，最烦就是打洞，请问一下老鸟们有没有用过探鱼器的si ？会不会一定要移动才行？

[莫德尔]

木用。除非你是开槽不是打洞。

用手慢速转呢？

没有用，si不是panoptix。

元帥只說了一半, 沒說的另一半是要造条track跟糟方向平衡, SI ff 放其上, 用人手以适当速度沿track 耒回把ff推动激活訊号, 应該可以 鵝是認真的

其实洞可以照打, 做个支架利手动将探头作耒回360*旋转也可以
Panoptix 能罩的角度好像还不到180*(110*? read that some how)....上校不正在啄磨着把Panoptix 探头旋呀旋的吗?

Lz 大可在家裡試試, 空中掛点实物, 手动探头, 了解一下屏幕的訊号....音速在水中是空气中的4.3倍, 所以屏幕顯示的尺度會是现实的4.3倍

估计实验不会成功，声纳探头发射的信号在空气中估计很难耦合到空气中，所以估计什么都看不到。
不过冰钓时应该可以使用si，只是如何解释屏幕信号而已。想象中，测量之后再转90度测试，然后应该可以估计出来吧。

"We used to "test" our ice fishing units by hanging the transducer off the edge of the table....like a plumb bob....it has to be in-line up and down(level) because air is not as dense as water (sound travels better in water)your mark or return signal is about 4 times the distance...off a standard height table around 30 " I get a signal at 10 '...so off your saw horses 4 times the distance you should get a blip....the only problem I can for see with this is if your transducer is not completely level you'll have to slowly rock it back and forth to "see" the blip.....start with your gain or sensitivity up to get a return...hope this helps"


This guy did exactly what I have done with my ff's many years ago
What the transducer gives out are sound signals, just like the way we talk & listen

有时间试一下。
