Very nice Abra,

the first picture looks a bit brighter. I would turn down sensitivity a bit and see if they have the same brightness.

Keep us posted Abra!

Beautiful Abra!

Comparisons of this kind are the best foundations for learning more about our systems and on how they can be developed. The images give further support for our statement that long cables are possible to use. The question is, how long can we make them??

for 800 khz
my thirst towfish 6 m lengh cable[attachment=1]
my second 60 m[attachment=2]
the scale is not same but there's not lot of lose signal
now i'm sure than i can work with 60 m as good as 6 meter for transducer cable ;)
