It does appear to have an effect, the problem lies in the need to have a constant power supply which, if on a swinging mooring could present a problem---Roger---
Hi Norman
I bought the unit after reading the comments on this page. unfortunately I did something wrong as everytime I switch the unit on the fuse blows. Being 3-4 times over and over and cant find the mistake.Can you assist? Thanks
With a sounder as I understand it, the reason for maintaining the cable length is that the depth measurement requires accurate measurement of the time between the transmitted pulse and its reflection... For antifouling that obviously isn't relevant. Of course, I may be completely wrong....When we buy echo sounders we are told specifically NOT to vary the transducer cable length. I believe the reason for this is that it's capacitance forms part of the transmit tuned circuit*, so fiddling with it could reduce the output power.
Does anyone (possibly with an aft cabin) get disturbed by the noise?

Hi all,
We bought and put together FOUR of these kits just now and the fuse blows on all four of them!

Why don't you try a slightly larger fuse?
Electronic components does have some tolerances,
so maybe you are getting slightly more current flowing.
It won't hurt the electronics (my guess) even if it burns as well.
I remeber, on one of my kits, one fuse burned with apparently no reason.

Tried that, it just caused one of the mosfets to overheat and start smoking before it also blew. ...
