by orlins on 1/31/2011 i nned to pay one deep vision course. You are welcome. How much. I have 2 deep side scan sonars
by u-11 on 10/20/2011 what would you prefere, 340 kHz sonar or 670 kHz? Why? May be you can show some differences on images... Thank you
by JimKennard on 10/20/2011 The DE340 (340 kHz) is used for deeper searches and has a towfish for deep towing and longer range over 250 meters. The Hull Mount (670 kHz) system is primarily used for higher resolution searches in depths up to 25 meters or so. I have actually used it in depths up to 60 meters. Hull mounted systems are more affected by every motion of the boat which causes image distortions in rough seas, whereas towed systems are not affected by the boat motion. Each system has its advantages, higher resolution and simple mounting with no towing, versus longer range and deep towing to be able to get under the thermocline layer and closer to the bottom. I have not imaged the same target with both systems but that is a good suggestion that I will do next season. Thanks for your inquiry. Jim

by Nauamchos on 2/6/2012 Hi,what is the depth of your image ? I'm looking for sonar able to work in the 100/150 mtrs range (bottom depth),similar to Yellowfin of Imagenex.
by JimKennard on 2/6/2012 Hi Nauamchos, The depth of sonar image of the Lake ontario schooner is in approximately 100 mtrs. Depth of the St Lawrence River sonar images vary from 20 to 70 mtrs. Hudson River images are 15 to 25 mtrs. The DeepVision DE340 should work very well for you in the 100 to 150 mtr depth range. Last year I found a steamer in a depth over 150 mtrs with the DE340. If you would like to discuss my experience with the DeepVision side scan sonar you can email me directly: kennard@shipwreckworld.com
