Golf Gadgets - Rangefinder/Techie recommendations?

[Hulatime]

Hi Golf Addicts! Am new to the sport and am smitten... so much so, I find myself shopping for golf-related items instead of watch stuff (for now)!

1. Am pretty certain I want to buy a Leupold GX-4i2 Rangefinder (mostly due to xlnt customer service reviews & the features) but is there another I should seriously consider?

2. Anyone use Ernest ES14 Golf Launch Monitor? Looks like it has could be fun/informative to use while I'm hitting balls. Anyone have experience with this or other similar device?

Thanks very much. If there's anything else I should look into, please advise. I did order a product from Arccos Golf. A set of sensors that go on each club & transmit info via bluetooth to an iPhone. It tracks a round of golf & gives immediate feedback for each club. Pretty cool but I'd like to use the rangefinder to see how accurate it is.

Anyway, great sport... lots of fun and super addicting. Thanks all.
