NASA Target2 Depth

[ssjpiv]

I recently purchased a second hand head unit to replace my old Seafarer 5 which was the size of a shoe box and difficlut to read with poor eyesight!

I have just wired the new one in this evening and am not utterly convinced by it.

It seem to intermitantley read OUT on the display.... I cant see in the manual I have what this means. (I only have the combined depth/log manual)

Also, I havent the exact measurement where my transducer is but knowing that I only draw a meter and knowing roughly where it was from anti fouling I have guessed at a keel ofset of 0.8m jut to be safe.

The only issue I have that I just sat having a drink on my boat as the tide came in and it only really ever got up to 0.3m, Which I think is wrong, we were sat in well over 1.3 m of water..... Am I missing something?

My mooring is a tidal muddy creek..... will this have some bearing?

Opinions/avice welcome.

Could it be a transducer problem? not sure if they are compatable.
I'm sure someone with more electrical knowledge will be along shortly and give you the A to Z on transducers / heads and how they work!

Nasa one is 150kHz so was the Seafarer 5

Nasa

I had trawled through the previous posts on the forum and the general opinion seemed to be that the NASA and seafarer transducer are compatable, both transmitting at 150...

the Nasa website tells you theirs is 150kHz Google finds a manual for the Seafarer 5.

Both 150kHz. Verifiable fact !

Gleaned from others, the intermittant fault is because there is not enough return through the hull and transducer is not adequate

Soloution

And the soloution being a new tranducer? Should this fault not have been present with my old unit if it is a transducer fault?
