Title: Newbie Question about SS coverage
Post by: erniel29 on August 24, 2011, 06:07:39 PM

I'm waiting for my 1198 to arrive and I have a basic question. How wide a swath can I scan in 10 ft of water?

In a perfect scenario, you can scan up to 240' on each side at 455khz.  Less at 800khz.

Here are a few topics to read up on.

Thanks, 130 degrees @ 800 khz. Now if I could just figure out Pythagorean theory for a 10 ft depth :).

Well, good rule of thumb for 800khz is 3 to 4 times your depth.  So lets say a max of 40' at 800khz.

Use Sin/Cos to figure mathematically.

Thanks, thats what I figured on. To me.. sin is what a gang member flashes to another, cos is how the other gang member replies.
