I don't have any info on the LVS62, but we have been using the PS30 transducer for a couple of years in deep water. It works really good. We can see a 1 oz., 5" tube jig at 140' and see when fish react as well as watch them chase all the way up. The cone angle is wide enough that I can see 4 different jigs in a 19' boat and tell which jig the fish is after. It doesn't require a "black box", the processor is internal. I rigged a pole up last winter and used it icefishing for lakers on Fort Peck in I think it was 75'. With the 135° x 40° cone angle if guys were relatively close I could tell them when they had a fish looking, and they could reel away.
