This is a very capable frequency counter with a couple limitations:. It is not a reciprocal counter, so the resolution in the audio range and below is limited by the gate time. For low frequency measurements, the DC509 reciprocal counter may be a better option. It is not high precision due to the limitations of its internal time base. Accuracy better than 1ppm requires the option 01 OCXO, which provides 0.01ppm stability. An external frequency standard can be readily connected by using ratio A/B mode. Within these limitations, this is a very nice instrument.

These are a nice set of tires at a much cheaper cost than the local stores. I haven't installed them yet and haven't put them to use, but they are an exact match to the set already on my 1971 Gravely Brush hog.

At $170 it was expensive for an older bobblehead. The wing nut which secures the bobblehead under a foot was missing so I had to replace that at my cost. The bobblehead was dusty so it must have been sitting out and not in the packaging, which should have lowered the cost.

Not bad. I put on my Gravely super convertible L8. The tread is not as wide as original good years. Still works and is a close match to the good year tires.
