2008 rz4 triducer replace???

[tigerzcan]

On my 2008 rz4 it has a threw hall triducer, but my depth bounces around like crazy and never reads right, the temp. Is about 15 deg. Off. So I'm going to replace my airmar triducer. Does anyone know the part number?? Also on my little digital display in my dash it says calibrate, what does that calibrate?

I'm interested to know how this works out for you. My depth finder reads 949.9 ft after about 20 minutes on the water. Had the local Tige dealer look at it and they said it had to be replaced. Said the part was $600!!!! Seems extreme to me.
