Type Key: D = Depth, S = Speed, ST = Speed/Temp, DST = Depth/Speed/Temp
Condition Key: "New" here refers to a transducer that has not been used and is still in its original packaging; in most cases the manufacture date was several years ago.

The buyer should be aware that the manufacturer's design life for a depth transducer is 9 years (including shelf life), and some of the transducers offered here are near or beyond this age. However, in our experience most depth transducers are able to actively function longer than 9 years, in some cases by a factor of 2 or more (there are exceptions). We've also not known a single case of a transducer in our stock failing during an extended shelf life.

If you are interested in a transducer whose status is indicated as "untested," you may request that we test it for a fee. If the transducer fails our operational tests, then the testing fee will be waived and the transducer removed from our offerings.
