Garmin Rino 520 Handheld GPS Navigator and 2-Way Radio Review

Garmin Rino 520 Handheld GPS Navigator and 2-Way RadioFor the longest time, I resisted geting a GPS. Any soldier worth his stripes should be able to figure out his ground position to within 100m just by comparing the ground to his map, and maybe shooting a bearing with his compass.

But then I picked up a cheapie Garmin Etrex, and while it doesn't replace the map and terrain reading skills (by a long shot) the ability to generate an exact position fix at a moment's notice comes in very handy, especially when one is operating in an unfamilliar area. GPS may be a crutch, but it is an *effective* crutch.

There were a few small problems with the Etrex though. It was very sensitive to sky view, such that it often lost signal inside a vehicle unless it was on the dash. It didn't do mapping, and it would eat AA batteries at a ferocious rate. With the newer, fancier units on the market, I started thinking about upgrading.

Many of the troops in my unit have Rino 120 FRS/GPS units. It can be handy to have an additional means of communication other than the issue radios, and the position reporting function was interesting, so I bought a Rino 520 - specifically a 520 vice a 530 because of reports of better battery life, and the extra geegaws on the 530 didn't seem to have much practical purpose.

Wow!

1) The 520 has tons of memory, such that I could upload topo maps for every area I was likely to operate in and still have room to spare. The detail and accuracy has been outstanding, and having street names (which the issue 1:50k maps lack) has been a godsend.

2) It is much less sensitive to sky cover than the Etrex was. It'll still lose signal if (say) stuffed in a glovebox, but it'll work on your lap in a vehicle, where the Etrex would not.

3) The "breadcrumb" track mapping means I can record everywhere I go, and then download the tracks to my computer later via Mapsource - which can then be overlaid on satellite imagery via Google Earth (which has already proven useful in proving that I was at a certain place at a certain time)

4) The routing function and the turn-by-turn instructions were recently tested on a 900km road move, and worked - although the unit made a couple of odd suggestions, and I think it may have been hampered by not having detail maps loaded for the entire route.

5) It has a nifty "alarm clock" mode, where you set the alarm, and the unit shuts off - and then turns itself on and screeches at the appropriate time. Cool!

6) The data pages are customizable, meaning you can set up pages that contain just the info you need.

7) The radio and position location/transmit functions work exactly as advertised. I don't yet have a good feel for the max range of the radio (even in 5W mode) but it's not huge. The speaker gets all distorted at max volume, but when used with an earbud it is just fine. My gut tells me the radio is fair to good.

8) The only real concern I've had has been battery life and the fact that it uses a proprietary batty pack that must be recharged from wall current - which can be tough to find sometimes. But so far, battery life has been exceptional (a three day exercise with heavy radio use only dropped to 60%, and a 2-day road move with the radio turned off finished at 90% used) and an add-on pack that uses normal AA batteries (at the cost of dropping max transmit power to 2W) is availible.

Overall, this is a great unit, and highly recommended.
