Today, it was windy as all get out, 34 degrees this morning when I launched after couple of days of storms,wind, cold, bright sun and fish on Lake Lemmon had lock jaw, but I did spend 7 hrs fishing caught 7 and only 2 were keepers with all released as I was also fishing muddy water after all the rain. Da ducer worked like a charm and very very happy with the 2 transducers on it. One the Hook 5, I ran sonar and chart, on the SI 7 ran the side scan and down scan and no interference from anything including trolling motor. If I ran sonar from the back of the boat as I have another 5 to drive with, the 2--5's had alittle interference with both set on 200..turn the back sonar off and none. Da Ducer Rocks!! Had the transducer and the trolling motor head about 18-20" deep in the water and no interference from either on front. And was fighting a 2' chop sometimes and da ducer took it like a champ. I like this setup for a Jon boat and really like the addition of Side Scan and picture I get on the lowrance SI 7. Was going to fish tomorrow, but they are calling for 10-15 mph winds gusting to 35 mph and don't think I want to fight it again. Will decide in the morning. Water temp started out at 55 this morning.
