depth
thoughts on "in hull depth sensor" or " transit mount sensor"

Just bought a Garmin 741xs with in hull transducer. Only problem I see is that it has a 22max angle, will have to glass in a ""pad" for it to rest on. We'll see if it accurately sounds thru the bottom of the hull...

There are transom mount, thru hull and transducers that do both. You need to check which one you have.
Thruhull works well if installed correctly (correct level, good epoxy, not near a chine that will interupt flow) and transom mount works the best if installed correctly (correct level, not near a chine or the drive which can interupt flow) The best thing you can do is install a gps unit that has a transducer as well as a good navionics card so you have 1. a point of reference for where you are "going" based on average water levels fluctuating based on tide 2. an actual depth reading as you are getting close. I think this was the first time that I had actual information for somone here instead of asking the question, cool!

Thru-Hull Transducers:
Advantages: No holes on the exterior of your hull to allow water to leach in and rot things out. Relatively easy to rig since everything is inside the hull. Disadvantages: Problematic readings with cored hulls. Difficult to mount the puck / transducer correctly. Tough to replace transducers. Transom Mount Transducers: Advantages: Easier to aim the transducer correctly. More adjustable. Disadvantages: Sealed incorrectly, goodbye transom. Ugly exposed external wiring. Silly little extra rooster tail. |
There was a spot between the engines on the centerline that appeared to be made just for the thru hull transducer. It appears to be a spot without any core material maybe 4"-6" square. I just glued it in with some resin and it has worked for 6 years with no problems.
