High-Def Sonar

August 17, 2011 by

Check out these screenshots from the new Simrad BSM-2 module and NSO Chartplotter. The BSM-2 uses advanced Digital Signal Processing to trasmit fish and bottom structure in incredible detail. These shots were taken by a Captain looking for swords in deep water off the Bahamas while running!

shot 11 640x480 High Def Sonar

Marking fish over 1420 feet while running at 18 mph.

shot 22 640x480 High Def Sonar

Clearly marking a nice bump with fish suspended using 6x zoom low band frequency in 1,279 feet.

shot 30 640x480 High Def Sonar

Even running at speeds of 25MPH BSM-2 easily shows substantial bumps on the bottom with fish life which were marked as waypoints while running using Simrad’s unique back track feature in depths of 2,448 feet

    This is very cool. Love to see it in action up here in our canyons.

    Pretty nice I’m using a low def lowrance and struggle to get that clarity with sun glare and clutter

    Hey Neal.
    I read with interest the January 2012 special edition article on the installation of the Simrad NSE System and wonder why you didnt go with the BSM2 and a CHIRP sounder.

    I’m in the market for a new system and cant decide whether to take the leap into CHIRP. NSS12, 3G radar, BSM1, LSS1, TM260 transducer.

    I mainly fish the western long island sound and the water off Rhode Island and Montauk during the summer.

    What are your thoughts on the BSM1 or the BSM2.

    BTW I dont have $$ to burn. Trying to keep the system to $5000 which is impossible with CHIRP.

      Hi Anthony – Thanks for checking in. The project boat in the January issue has been in the process of being refit for a couple of years now and that electronics package was actually purchased in August of 2010. The BSM-2 and CHIRP came out in the fall of 2010 and is a generation better than the BSM-1. Today technology is moving so fast that it’s tough to keep up. I love the BSM-1 but if you want the latest and greatest it would make sense to upgrade to the BSM-2. Look for us to cover the new CHIRP technology on the website and in upcoming issues of On The Water.

      Thanks again.

      Neal
