Look for old IC-4AT or similar handhelds at hamfests, and pair it with a controller such as the PICCON.
I have a number of IC-2ATs that I use on 2m in an ammo can with a battery and controller.  Don't
try to run them continuously at full power, of course - put them on low power or set the controller
to intermittent cycle.

In fact, one simple way for a club to get started is to purchase a controller of some sort and let each
hider build an adaptor cable for the radio(s) they want to use.

I agree a PICCON is the way to go with a super cheap thow-away Baofeng UV5R dual band ($39) you would be setup to hunt on two bands (you might be able to cross-band to torment the Hunters even more). But soon the Hunters will stress at the severe multi-path of 440. You may want to try 2m, the common T Hunt band - 146.565. 

Look around for some used 30/50cal ammo boxes to put your Fox into, they are WX/water proof. You can spray paint them cammy for additional concealment. I put a feed-thu BNC connector on the lid that can double as an antenna mount. I made brass rod 1/4wave BNC antennas for the Fox. I even cammy tape them too. If lost or bent it is nearly no cost loss.

Making the HOL type tape-measure beam is easy and cheap to do.

I have many info articles on my Yahoo Group 'USA-RDF' to view/use even a 460 RDF beam for FRS/GMRS use.

After first fox hunt I  I noticed I need protection for the fox so I last week decided to place in 50 cal ammo box.
Also did following upgrades:
- 10 db Attenuator installed in 1 db steps
- 7 amp hour battery to run Radio and Piccon
- Baofeng Battery eliminator to hook to battery in ammo box
- Can use rubber ducky antenna or I Can use magnetic and change polarity
- On/Off Switch turns everything on instantly and can DTMF enable the piccon remotely.
