Thread: ? for RICKY

No I sure don't Wilbur....

I would assume they are similar to the HB and, if so, the 455kHz would go all the way to the surface...

This would mean that you would get some blockage from the HDS 2d Xducer if they were mounted at the same height...

I've seen your posts at bbc and I can empathize with your situation having a tin boat and trying to find satisfactory mounting places for the Xducers....

My suggestion would be to experiment with the LSS Xducer first to get the SI images you want and then experiment with 2d Xducer to see how much "SI blockage" you can live with to get your high speed readings...

After all, if there is blockage and it shows up as a white line close to the center line of the SI image...it's very unlikely that fish or bait are going to be that high in the actual water column for this blockage to cover up the returns of the suspended fish and/or baitfish...

You might investigate the Alumaducer to replace your HDS 2d Xducer...
