     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular to FIGS. 1 to 6 thereof, a new and improved pool thermometer apparatus embodying the principles and concepts of the present invention and generally designated by the reference numerals 10 and 10a will be described. 
     More specifically, the pool thermometer apparatus 10 of the instant invention essentially comprises a support housing 11 that includes a central cylindrical body 12 coaxially aligned with an upper cylindrical body 13, wherein the central cylindrical body 12 is defined by a first diameter and the upper cylindrical body 13 is defined by a second diameter greater than the first diameter. The central cylindrical body 12 includes a lower threaded housing end 14, with the upper cylindrical body 13 including an upper threaded housing end 15. A lower internally threaded cap 16 coopeartes with the lower threaded housing 14 and including a lower cap seal 17 interfitting between the lower threaded housing end 14 and lower internally threaded cap 16 to effect a fluid impermeable at a lower terminal end of the support housing 11. The upper threaded housing end 15 coopeartes with an upper internally threaded cap 18, including an upper cap seal 20 to effect a fluid-tight relationship between the cap 18 and the housing 11. The upper 18 includes a central opening 19 fixedly mounting a transparent lens 21 coxially aligned therewithin to overlie a printed circuit board 22. The printed circuit board 22 includes a light-emitting diode panel 24 that is operative through a temperature sensor 27 projecting through a temperature sensor sealed aperture 28 through the central cylindrical body 12 for providing detection of ambient water temperature. A battery 25 is mounted below the printed circuit board 22 coaxially aligned within the central cylindrical body 12 defining a center of gravity of the support housing. The elongated battery 25 is mounted by an alignment band 26 that complementarily receives the battery 25 and maintains alignment of the battery 25 by the alignment band 26, including an external diameter substantially equal to the first diameter. An on/off switch 29 is operative with an illumination bulb 41 to effect selective illumination of the bulb below the translucent printed circuit board 22 permitting saving of electrical potential within the battery 25 as required. 
     In this manner, the support housing 11 defines a fluid impermable cavity between the upper cap 18 and the lower cap 16, with the battery 25 contained within the central cylindrical body 12 to orient the organization in a vertical manner within an associated body of water. 
     A modification of the invention set forth as 10a as illustrated in FIG. 6 to include plural pairs of socket tubes 30 fixedly mounted on diametrically opposed sides of the upper cylindrical body 13. Socket tube 30 of each pair of socket tubes includes a respective first and second support rod 31 and 32 extending an opposing direction tangentially aligned with the upper cylindrical body 13, wherein a respective first and second support rod 31 and 32 arranged in a parallel relationship mount a respective first and second cup holder 33 and 34. The cup holders permit reception of various drinking containers therewithin. 
     Each cup holder includes a plural pair of support posts defined by first and second pairs of support posts 35 and 36 of the respective first and second cup holders 33 and 34. The support post 35 and 36 are othogonally oriented relative to the respective first and second support rods 31 and 32 that intersect the support posts, wherein each distal terminal end of each support post includes an anchor tether line 37 mounting an anchor weight 38, wherein the anchor weights at each distal end of each support post provides ballast and alignment of the support housing 11 and the first and second cup holders 33 and 34 within a body of water. Further, a respective first and second suction cup 39 and 40 is provided and mounted to an upper circumferential perimeter of each respective first and second cup holder to permit securement to an associated side wall of a swimming pool and the like for maintaining desired orientation of the structure during use as a cup holder apparatus. 
     As to the manner of usage and operation of the instant invention, the same should be apparent from the above disclosure, and accordingly no further discussion relative to the manner of usage and operation of the instant invention shall be provided. 
     With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention. 
     Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
