The AT2 dual transducers only work on the HDS Pro, You can run 1 AT2 on a Live. Which has more range and distance and image clarity than the AT1 besides the shallow water performance of the Scout Wide Image of AT2. If you are trying to save money by running an AT2 transducer on your current AT1 module You will have about a 10% Image Degrade. Personally I would never do it. Sell the one to someone just getting into Live Sonar. The Dual transducers on the HDS Pro is one of the advantages of the Pro,
The 3100 Module is what is needed on Carbons, Lives and FS units to get the Chirp into the Megahertz Range adjustable from Low to high Chirp in Down Scan, Side Image and Sonar. The box has 2 1KW Sonar channels that support Airmar transducers and the new Lowrance 3-1HD Fish Reveal HW and Fish Reveal MH and HD 3-1 transducers. The box for fish Reveal is also needed on the HDS Pro for running Fish Reveal. if you don't want Fish Reveal the 3100 is not needed on the Pro. This box is basically a complete sonar unit without the screen. When you add this to a Live, Carbon or FS unit you get a lot of frequency and depth flexibility on your units depending on what transducers you choose. The down scan and the side image frequencies are independent so you can dial in ea screen with the freq that gives you the best image you seek, For a very low price to change your unit into a flexible range of frequencies from Low to High into the Megahz Range compared to the cost of buying a single unit to accomplish over the cost of the 3100 and Transducer. Choose wisely on the transducer selection for your type of fishing. if you don't understand get the facts before you buy. There are many more smaller upgrades that the new HDS Pro will do. There are also a lot more software upgrades for both AT2 and the 3100 and Ghost coming that have not even been talked about yet as they are a little behind on software with so many new products. But nonof this will stop you from using the newest Fishing Tech. If everyone remembers there were lots of new upgrades for the HDS Live over Time and they are not done yet. I don't remember this many new big products at one time I guess that is what happens in pandemic times. Enjoy
