Title: Marking schools of fish at speed?
Post by: Rotus623 on June 14, 2014, 05:44:45 PM: Hey guys just wondering if anyone has good experience with this. I have an 898 at the console and I am hunting for large schools of landlocked striped bass. My transducer is set very well, and I get minimal turbulence at high speeds. I can easily read the bottom very clearly at 30 MPH.

Cruising speed for me is 21 MPH. I would like to get an idea what the screen looks like over top of schools of fish (particularly striper, but any schooling fish would be great) at speed. These are some shots of feeding stripers at trolling speeds.

And here is just a great example of what striped bass look like on SI.

The unit will lose bottom at these speeds more than we realize...and a Max Depth setting much less than the factory default of 1500ft will make the unit perform better...
