First and foremost, like deer hunting, the wind can bust your efforts. I carry a wind powder in a small squeeze bottle and will check the wind at each of my moose bog setups and discuss strategy with my guides. I use some Dead Down Wind powder.
And I have 4 bottles of synthetic moose/cow-in-estrous urine and will use it as a cover scent and attractant. Reviews say the scent works and I will test it too.
I would have liked some bull moose urine too but could not locate any. If when hunting, I find a moose wallow, I will put some wallow urine on a rag and carry it for cover scent. Moose will not fully come-in if they suspect any human smells thus the scented rag trick can work with either estrous or bull scent.
If all is right, I think calling by mouth is a good initial strategy for me and listen for a bull to respond. I am pretty good at calling with my hands or a funnel type caller. Being able to make a long vibrato call for a cow mimic or a staccato-like grunt for a bull..
I just learned that moose talk, between moose is usually a “rrruh” sound that says “I am a moose”. Good to use if you are making noise getting to your stand to cover your mistakes
I like to mock-stage-a-fight, raking trees and making a racket with a moose scapula. It’s great fun too. I killed a New Hampshire bull with that tactic.
I sometimes use the tending grunt if a bull is located, where you grunt by pinching your nostrils and cone your hands and “softly” say mwahh and mwahh as if saying, me want, and the “t” is silent. This tending grunt indicates a bull is tending a nearby cow-in-heat. If the listening bull is in rut, he will likely challenge the tending bull and show himself.
Below is a great video on moose vocalizations and raking antlers and how moose talk to each other. A must see… But the video did not talk about moose wallows, where male urinate and roll in it like a cologne for the ladies.
If at a distance we will use a power electronic caller. If he is close we can try to mimic a bull and thrash and rake trees with my moose scapula. If all goes well this September we will have a 1000 lb moose to quarter and haul out. Once boned we will have roughly 300 pounds of delicious meat to freeze and eat. And maybe a large rack of antlers.
Below is my small racked bull taken in 2018. It does not look big in the photo but was 300 pounds of meat to take home.
I am hoping for a much bigger rack this trip.
Good Hunting!
As my readers know, Soon, I will be moose hunting in Newfoundland in September. You might be interested in my hunt gear below. 
My Browning X-Bolt Speed was checked by my son Jason with Nosler 175g ABLR bullets at his F-Class range at 300 and 600 yards. My scope is the famed Leupold VX-6 3×18 44mm on a 20 MOA Picatinny rail.
If you didn’t read my last article on this rifle, bullets, powder and primer. Here it is…
