I agree with Megabytes. TR-1 is an excellent system. If you stick with Furuno, you cannot go wrong with the RD30.
Was thinking of you today. Went fishing today off NJ and had 100+lb bluefins surfacing all day about 2 miles offshore. The fish were moving S. very fast and should be in your neck of the woods very soon. Unfortunetly, we could not troll any, conditions wer every nasty today and trolling would have been a mess. Ended up jigging Stripers even though we had the offshore gear onboard. Ended up giving my buddy some of my lures I rigged with your birds and Slammers after I showed him pics of the bluefins we crushed this season. Guess I'll be putting in another order shortly.
