Is the rrampmeter one of the best ways to test track around a large outdoor layout, or are their other options For DCC?

Are you familiar with voltage drop testing? It is used a lot in auto repair circles to chase down wiring issues. All you need is a straight DC source to put across the rails, maybe the power supply for your central station (24v DC?), a couple of 12V automotive bulbs in series on alligator clips, or a single bulb if using a 12V supply and your VOM. Connect the bulb(s) across the rails at various locations and check the actual voltage across to the bulbs. Start at your feed connections to give you an idea of what a good (hopefully) voltage reading looks like. Keep a record of your readings and you should be able to track 
down where any problems such as bad joints exist. Bulbs are convenient but any load that will draw a few amps at your test voltage will do. Make sure your central station and boosters are disconnected when you do this testing otherwise they WILL BE DESTROYED!

A RRampmeter is a specific meter intended for use with model rail DC and DCC systems.

A RRampmeter is
IMO a RRampmeter is a great tool for any DC or DDC system as it conveniently combines a bunch of functions which would otherwise require several different devices. I have one which I bought initially for use with my DC trains and it is now starting to be equally useful with DCC.

Whoops! Basically a multi-meter for model railways then

I use the Massoth 1200Z DCC and it has a reading for Current on its LCD display.
I'm not familiar with other manufacturers kit.
For fault finding, I use a conventional Digital Multi-meter, but PhilP's light bulb method works just as well....

A multi-meter that correctly reads DCC volts and amps....
Question is about DCC... ordinary meter not accurate.
As per debugging, a proper meter AND proper debugging techniques are both needed.
The major thing people do wrong is not test under load.
I have a page dedicated to techniques on finding and debugging problems with track power, too much to retype here.

If you read the page I linked to, it's called the "clock problem"....
