Charly,
Over the years the busiest booths I have seen include a couple of pretty blondes in it!
One year at SCI, the girls from the Rack Calendar were attracting so many people that they were blocking the aisles... :shocked:
I think standing apart from the rest of the booths is key to getting noticed, and in my opinion this can be achieved by using a dominant bold color throughout your booth, including your main display, table coverings... a bold color such as a rich red or blue, a color that stands out from the usual camo or hunting colors that you find at a show. You might find it to be a bit too much at first but once you have added all of the other elements of your booth you will quickly see it more tamed...
Another important aspect is name recognition, make sure that your logo/company name is prominent, well placed and readable from quite a distance. Also as most logo/company name do not tell the entire story, for me it is important to include a tag line defining what you do/specialize in so that visitors of the show know exactly what you do or what you are about without having to ask.
Your back display should have big (trophy) pictures on it to capture the attention of your potential clients, don't short yourself there, for me better 4 big impressive pictures than 8 or 16 smaller ones that no one can see... These pictures should also tell the story, by that I mean if you have a Bongo picture it immediately tell the visitor what you offer or specialize in these type of hunts...
The back display should also be used to display a great offer to drive potential clients to talk to you. I would choose only one SPECIAL to display, again, big and easy to read. Other offers can be on a flier displayed on your table.
In your case, the back display should also list the names of the countries where you are selling hunts to.
For me taxidermy mounts are not imperative, but if you choose to have one, keep it at one. Better have one that draws your attention to it than 3 that get lost in the environment or fill in the entire booth... Also a rare, unique or record trophy mount can draw lots of attention, sometimes exhibitors use one huge mount as their main focus point to attract people's attention. One big statement can make the difference.
Obviously having a table and chairs to do business at and a place to sit is beneficial as shows are tiring. The busier your booth is with people the more others will be interested, so invite friends and past clients to come and hang out... there is nothing worse than having an empty booth. People attract people.
TV's for me are more distracting than anything, and I do not care for them... but some people enjoy that.
I think another nice touch is to have a cooler with some water to offer someone you are talking to, it may be the difference between them sticking around a little bit longer and having the opportunity to talk to them a little bit longer.
Hope this help. I think that it would be great for others to offer what they think is appealing or "works" whether they are outfitters experienced in the show circuit or hunters who visited shows.
