I use marine electronics commercially, Garmin does have great customer service but sadly like some great warranty scope companies you will use it. Ive never dealt with Indian based customer service, its always been someone in Kansas.
I'm down to rhino radios on my boat, they've never finished a season even being babied, they have a reasonable warranty until they run out of parts. Furuno they aren't. But they are good enough if try a chronograph from them, although knowing full well they change model numbers so fast in 5 years they won't have parts.
In the market for a chronograph as well, used a Labradar last week... it was OK. Id still need another for my high speed varmint guns, so it would require 2x purchases.
