APPENDIX 2 INSTALLATION OF TRANSDUCERS
AP-6
Avoid Overheating
Installation Supplement: CHIRP Transducers
17-573-01 rev. 05 04/01/14
CAUTION : Follow the instructions that came with your transducer. To install a
CHIRP transducer in a way other than intended by the manufacturer may lead
to the transducer overheating, resulting in transducer failure.
Due to the nature of CHIRP technology, CHIRP transducers generate more heat than traditional
tone-burst transducers operating at the same frequency. CHIRP transducers have heat sinks in
their construction to dissipate heat. Airmar’s CHIRP transducers have been designed to be
installed in specific ways according to the number and placement of these heat sinks.
External Thru-Hull Mount
Models: B265 LH/LM, B275LH-W, B765 LH/LM, R109 LH/LM, R109LH-W, R509 LH/LM,
R509LH-W
Transducer is installed entirely outside of the hull. A stem or stuffing tube hole is drilled through
the hull for the transducer cable. The active face and sides of the transducer are immersed in
seawater.
Tank Mount
Models: CM199 LH/LM, CM265 LH/LM, CM275LH-W, CM599 LH/LM, CM599LH-W
Transducer is installed within a seawater-filled tank outside of the hull. A stem or stuffing tube
hole is drilled through the hull for the transducer cable. The active face and sides of the
transducer are immersed in seawater.
