Ok, seems it is the same.

|arf145||Sorry, don't know the transducer model--it's the dual frequency model that came with the unit. Made by Airmar, I believe.|

|csilva||Thanks. Do you know the model of your tranducer? Mine says it is a "transmon mount depth and temperature transducer, 50/200 kHz" and yes, I believe the hull is solid (I will double chack, though).|

|arf145||I've been using a shoot-thru transducer for my Garmin 545s for a couple of seasons now and sensitivity seems fine. I placed the ducer a few inches off the centerline but don't know the hull thickness of a Pearson 28-2 at that spot. I didn't give hull thickness a thought, but do make sure your hull is solid and not cored--that's a show stopper.|

GARMIN GPSMAP 421s
Has anyone experienced with a shoot-thru-hull transom transducer installation? Seems nice to avoid drilling a hole in the hull, but what happens to the sonar sensitivity? The installation instructions specify that hull can be no more than 5/8" (9.53 mm) thick; any idea on the thickness of a Tripp 33 hull?
