i currently have 2 brass thru-hull transducers with the ends that would go into a fish finder, installed on my boat with no display units. i can't find any I.D. numbers on them at all. all i can find is the word AIRMAR. the issue i'm having is how the hell do i know what unit they will work on? from what i've seen in doing research (airmar web site) on transducers these are quite expensive so if i can find out what they are for i could buy a display unit to match and not have to buy a transducer. any ideas would be great!

check again (outside too) for p/n

Airmar supplies most, if not all of the transducers for just about every make.
Try giving Jim a call at BOE marine. He or another knowledgeable person there should be able to help you figure it out.

Oh, and one more thing. The numbers you're looking for, are usually printed on the cable itself.

thanks guys. i never checked the cables for numbers just the transducer bodies. the one display connector has 10 pins and the other has 7 or 8.

Good tip Jamie - I didn't remember Airmar's #s being on the cables, but I knew they had to be on there somewhere - they're very meticulous.

I guess the only danger is if you hook a high power (100W+ ) sonar to a smaller transducer and it burns it up ... otherwise let her fly.

Some are not 50/100, but you don't know for sure until you try. They do go bad so they may not work anyway, but who knows until you try?

right. all i can do is try! it would save me a few bucks if they worked but in the boating world what the hell is a few bucks?! that just made me think of a good boat name... BROKE BUT FLOATIN'.

Airmar is the transducer I just put in a couple weeks ago for my new Garmin. Garmins website has a diagram of the transducer ends that shows the diameter and how many pins for each unit.
