Hi Seafever. Narrower beam equals deeper penetration as you have the same power concentrated in a smaller area but.........
The "deep penetration" is primarily for water 1000 or more feet deep where Billfish tend to run at when they are not feeding - they come-up to investigate the noise of the boat, see the surface-trolled gear, & strike.
If your balls are within the cone angle of your transducer, you could probably see them with 5 Watts of power; they are hard & reflect the transmitted sonar pulse very well.
There is a Guy named Gil Travis who sells this stuff. He is a former military sonar expert. His handle on The Hull Truth is Semperfifishing & he can be reached via email at:
