Garmin TM270W Fishfinder Transducer TM270W-8G

The TM270W is a 1kW wide-beam transom-mount transducer with temperature sensor that gives four times the beamwidth at 200khz than other high-performance models. Since the beams are the same width at both high and low frequencies, you will see unparalleled detail throughout the water column and will be able to detect fish around the boat that would have gone unseen before. The TM270W’s included stainless-steel high-performance mounting bracket is easy to install and delivers high-speed performance up to 30 knots.

The TM270W is shipped as a generic 'Mix and Match' transducer plus a brand-specific adapter cable. If you change fishfinder brands in the future, you can continue to use the transducer with a new adapter cable.

This '-8G' version of the transducer is for Garmin sounders and fishfinders that use an 8-pin transducer connector (currently only the GSD 24).
