Velocitek Speedpuck option
I've been researching Velocitek's Speedpuck. In comparing it to the Garmin marine GPS handhelds it looks like the Garmin marine GPS handhelds have a lot more features than the Speedpuck for less money. But, I like the large display and simplicity of the Speedpuck. I have a small keelboat and do not like the idea of adding a throughhole impeller a real knotmeter. Too easy to damage with trailer and prone to clogging.
The Speedpuck seams like the perfect substitute for an impeller knotmeter for people in my situation. However, I am hung up on the price/feature ratio. I don't need all the other features of the handheld GPS. Has anyone tried the speedpuck as as substitute for an impeller knotmeter? Is the Speedpuck a good choice over the handheld GPS? Are there other similar products to the Speedpuck at a more reasonable price point?
