Equipment recomendations

[jdbravo]

I have a 32-foot sport fishing boat, currently equipped with a Humminbird Helix 9G3N GPS CHIRP MSI chartplotter. However, I would like to add radar functionality, primarily to detect birds and weather conditions.

Additionally, I need a fishfinder with a transducer that can be mounted on the transom.

What combination of chartplotter, radar, and transducer would you recommend?

Thank you!

What depths do you fish?

What depths do you fish?

I fish starting at 40 yards and reaching much greater depths in open waters.

What are the deepest depths you normally fish?

I bought the TM165HW and lost it within a week of use. So, I’ll look for a transducer that can work through the hull (without drilling) or, if strictly necessary, a thru-hull one.

The maximum fishing depth is 300 meters.

In-hull transducers lose a lot of signal into the hull and CHIRP doesn't work well through the hull typically. You might think about pocket mounting something at a good position on the hull.

I think I'll go with with the thru-hull option, which CHIRP transducer may you recommend me if I fish between 30-300 meters?

Because you want radar that can do bird detection, I would recommend the DRS4D-NXT radar with a TZT10X or TZT13X display with a B175M transducer. A value system would be the GP1971F with B175M and DRS4W. The 4W isn't setup for bird location and really wouldn't work for that part but it would offer radar to a lower cost system. This would be single freq CHIRP. If you want dual freq CHRIP, I would recommend the B265LH-12pin with the XL system.

Regarding the transducer, I have two potential mounting locations:
1. In the middle of the boat, under the cabin. However, the surface here has a 30-degree angle, and the B175M transducer has a maximum tilt of 24 degrees—am I correct?
2. Near the stern, approximately 50 inches from the rear of the boat. This spot offers a flat surface (0-degree tilt) but is located behind some water inlets, which could potentially cause interference.

Which one will work better ?

 

[Johnny Electron]

You don't want water inlets in front of a transducer, that is for sure.
The transducer should be level with the bottom and the faring block cut to the angle of the hull to ensure that the transducer is pointed down. Fairing blocks are used to push the transducer down in the water and to be used to fit it to the hull. It would be the fairing block that gets cut to the 30 degree angle.

 

[jdbravo]

Are we talking about the same transducer? The B175M is is a flush mounted tilted element, no fairing block

 

[Johnny Electron]

Sorry got my lines crossed. B285M.
