This source claims that they have the best gamma probe value in the market like other websites claim their product is the best.
The company claims that the Dilon Navigator is
◙ Lightweight and compact
◙ ultimate in portability
◙ advanced battery technology
◙ the control unit in the OR without the limitation
This is supported by the website and source but this claim is an opinion cause while some people may believe this is the best product others might prefer other ones. With this being said other sources do claim that the Dilon is the best. As it states in the source FirstWorld HealthTech
"The advanced control system and the ergonomic stainless steel wireless probe provide the best value among all other gamma probes in the market."

At the end of the day Dilon could be the best gamma probe in some cases to some and others may not think in this way. One thing is for sure is that other people definitely do agree with this claim.
