I have the 600L and used the brass through hull ducer with the speed and temp works great and I get readings going 35 MPH with no problem. If you want your 600L to do what it’s capabilities are go with the through hull ducer with the 50/200 khz cost is about $200. Most guys are intimated in putting a large hole in the bottom of their boats. But that’s the way to go to get your best results. I cut out a hole the size of the entire ducer (football shape) out of the center line of the bottom of the boat about 3 ‘ from the transom. I flush mounted the ducer and used fiberglass with epoxy to build up a frame on the inside of the hull to keep it in tack, solid, and dry I used 4200 to seat it. I don’t get any cavitations since it is flush with the hull and since it is on the center line it is reading directly down not on a 20 degree angle. What you need to do is go buy a double six pack of Budweiser drink a few and then start the job the buds will help in the fear factor of “CUTTING A BIG HOLE IN THE BOTTOM OF YOUR BOAT”.
