A connector includes a first housing section having a plurality of electrically conductive contacts therein. The connector also includes a second housing section including a plurality of electrically conductive contacts that can form an electrical connection with the contacts of the first housing section. The first housing section and the second housing section are removably connectable and are capable of forming an explosion proof or flame proof housing when connected. The contacts of at least one of the second housing section and the first housing section are movable relative to their respective housing section to align the contacts of the second housing and the contacts of the first housing section during connection of the second housing section to the first housing section. Electrically conductive connection between the contacts of the first housing section and the contacts of the second housing section occurs during connection such that when connection between the contacts of the first housing section and the contacts of the second housing section occurs, the first housing section and the second housing section are in sufficient connection to form an explosion proof housing.

An instrument system includes an instrument assembly having at least one fitting projecting therefrom. The instrument system further includes at least a first housing member including at least one alignment member located therein. The alignment member preferably includes at least one sloped surface which slopes toward at least one seating adapted to seat the at least one fitting of the instrument assembly. The instrument system further includes a second housing member which forms an explosion-proof enclosure with the first housing member to enclose the instrument assembly. The second housing member preferably forms an explosion-proof enclosure with the first housing member via cooperating threading. The instrument assembly can, for example, include electrical components for a combustible gas sensor.

A sling seat is useful for enabling hunters to sit comfortably in trees. The sling seat comprises a tough flexible seat member having pairs of aligned and spaced slits therethrough. A long flexible strap passes through each pair of slits such that the strap underlies the seat member. The strap ends are buckled to any convenient tree limb for supporting the seat member in practically any desired location within the tree.
